Ted Jeo and I have both written about the Rhineland Arms
.45 ACP conversion kits for the Enfield No. 4 rifle. Ted
wrote a great article on installing the kit and
I inadvertently wrote about how to blow one up. |

Before you go and start Googling the term Rhineland Arms
let me stop you right there...they do not make their kits
any longer.
Recently I received the following
email: |
|
|
Jamie,
I saw your article on the Rhineland .45
Enfield. I thought you might be interested to
know that our new upgraded version is now
available. We have made several improvements
over the Rhineland version.
More details on my site...

I emailed Richard and told him I had an idea for an
article. Shortly afterwards we spoke on the phone. I told him that I
could not install the kit on my own because I have
limited dexterity with my hands. I offered (since I live
in Sacramento) to drive up to Gardnerville and document
him installing his new kit for an article.
He agreed and I drove the two hours to where his
facility is located.
One note...if you ever have the chance to drive into
Gardnerville from Lake Tahoe, please do. Gardnerville
sits in the very flat Carson Valley. You are several thousand
feet above when you crest the mountain and look down at
Gardnerville. I have only to say the view is breathtaking. |

Now onward with the gun stuff. I searched through my
collection to see what I could convert and still
maintain a good conscious about afterward. One of my all time favorite
rifles is the
Enfield
No. 4. I have several pristine specimens that I
would rather open a vein in my wrist and let the life
drain from my body before I would tear down one of these
rifles for permanent modification. I did however find
what I believed at the time to be a perfect candidate
for this project. It was a No.4 that someone had
shortened to less than sixteen inches and then installed
an aftermarket
Enfield
No. 5 Conical Flash Hider on it to make it the
Federally required sixteen inches in length. It always
made me nervous as to whether it really met the
letter of the law, so it stayed locked up until someday I
would decide what to do with it. Heck, it did not even
have a bolt. I owe Richard a great deal of thanks for
being patient with me, as the missing bolt caused a
great many problems with the conversion, mainly in the
length of time it took to fit the parts. As much as the
later Enfields were manufactured using modern mass
manufacturing techniques; the spare parts do not always
fit properly without some modification. This was
the problem we found when trying to find a matching bolt
body and bolt head to go with my receiver.
DO NOT SEND A RIFLE TO SIA THAT DOES NOT
HAVE MATCHING PARTS! |
|
|
|
While Rhineland Arms was making kits SIA used them as
the basis for their suppressed .45 ACP Enfield carbines as
pictured below in figure 49. All the while Richard had
ideas about improving the function and quality of the
kits Rhineland Arms made. So when Rhineland Arms quit
making the kits he found himself with a large
number of unfilled orders for his suppressed carbines
and no parts available. He decided he had no choice but
to make his own improved kit.
The basic SIA kit includes the barrel, magazine
adaptor, magazine, and ejector assembly and looks like
the Rhineland Arms kits on first inspection. When you
start to look closely then you start to see the
differences.
- The ejector assembly is a spring loaded
precision unit instead of just a screw.
- The magazine adapter is a much more precision
made device that does not require you to modify the
rifle like the Rhineland kit did.
- The magazine ejector is also far superior to the
Rhineland kit.
If you are inclined to perform the modification
yourself, SIA will send you a kit in the "white" as
pictured below so you can apply your own finish to the
barrel such as DuraCoat, Hot Bluing, etc or you can
have the barrel Parkerized by SIA as I did. SIA also
offers a number of very reasonably priced conversion
services so you don't have to worry about removing your
old barrel, headspacing, parkerizing, or drilling & tapping
as these can be somewhat advanced tasks for the average garage
tinkerer.
For my conversion I opted for a complete
reparkerizing of all of the metal parts and an Glass Filled Nylon Black
Advanced Technology Inc (ATI) Enfield No. 4 Monte Carlo
rifle stock.
The following is a combination of SIA's instructions
and my photos of the process of conversion. |

Information |
- An ideal conversion for anyone desiring
a relatively quite gun that is inexpensive
to shoot, with minimum recoil.
- Good for target shooting, but still
powerful enough at ranges under 150 yards
for most small to medium game hunting or
self defense.
- An excellent choice for those who would
like to have a rifle in the same caliber as
their hand gun.
- A great gun for youth or ladies to step
up to from the .22 before graduating to high
power rifles.
- A superior platform for suppressor use
where legal.

The adaptor arrives
preassembled, except for adjusting the latch
piece (The tapered aluminum block with two
holes, at the rear of the adaptor), no
adjustments or disassembly should be required.
The inverted "L" shaped
stainless piece is the magazine release.
Once installed it is recommended
that you leave the adaptor in place unless it
must be removed for cleaning.
Reloading should be done by
removing only the 1911 type pistol magazine. |

How To Remove Your Old
Barrel |
-
It may help to soak the
action and chamber end of the barrel in
penetrating oil for a couple of days.
-
You will need a very
sturdily mounted bench vise.
-
You must support the
receiver in order to prevent warping it
while unscrewing the barrel.
-
Action wrenches are
available from gunsmith supply companies
such as Brownell's. $70-$120.
-
Alternately, if you are only
doing one conversion, you may be able to
make a receiver clamp from hard-wood or
aluminum.
-
You want to hold the
receiver tight without crushing it.
-
A pair of blocks cut with an
internal shape similar to the receiver
exterior should grip the area around the
barrel base.
-
Clamp the receiver in a
vise, grip the barrel with a barrel wrench,
or if you are not concerned with saving the
old barrel, a large pipe wrench may be used.
-
The barrel is a 1-14 right
hand thread, once you get it to budge it
usually comes off fairly easily.
-
It is better to spend a
few dollars as instructed here than to ruin
your receiver!
|
|
How do I get my old barrel
off when it's REALLY stuck! |
-
If you do not have access to
a lathe, a local machine shop or gunsmith
can handle this for you at a nominal cost.
-
Many Enfield barrels are
extremely hard to remove, they have been on
the gun for about fifty years! We find that
the easiest way to get them off the receiver
is as follows.
-
Strip the action out of the
stock, remove the rear sight, and all small
parts which might come loose while the
action is spinning in a lathe.
-
Strip the bolt assembly, you
will need a firing pin removal tool.
-
Insert the bolt body into
the barreled action.
-
Mount the barreled action in
a lathe with a "swing" of 9" or larger.
-
At the receiver end place
the firing pin hole of the bolt body on a
live center mounted in the tail stock.
-
Chuck the barrel in a self
centering three jaw chuck.
-
At very low speed turn off
the barrel shoulder (Chamber area just in
front of the receiver) to 1" diameter using
a thin blade parting tool. Wear safety
glasses!
-
This will relieve pressure
on the barrel shoulder and threads, the
barrel should now unscrew easily.
-
Since the barrel shoulder
has been machined back the barrel is now
scrap, this is not a problem, you are
fitting a New .45 barrel.

|
|
|
|
When Richard first attempted to remove my barrel from
the action with a receiver wrench, he almost snapped the
receiver in half because it required so much torque. He then
moved onto a more trustworthy way of permanently
removing the barrel. I say permanent because you install
the barreled action into a lathe and then remove some of
the barrel shoulder that rests against the face of the
receiver. You do this till the remaining material is about
one inch in diameter. This act will remove enough
pressure on the barrel shoulder and threads so the
barrel can be easily unscrewed. |

Enlarge the Barrel Channel
in the Stock |
|
The .45 bore is significantly
larger than the original .303. This requires
that the .45 barrel exterior must also be a
little larger, so it will be necessary to open
up the barrel channel in the stock. This can be
done with a hand grinding tool and burr, or
round wood rasp. Once the channel is close these
tools should be followed with coarse and fine
sand-paper wrapped around a suitable piece of
wood dowel rod. |

Drill and Tap Receiver for
the Ejector Stud. |
-
Use a sharp #29 drill and a
8-32 tap.
-
Locate the hole 1.25" back
from the square edge of the barrel trunnion,
and .788" from the bottom of the receiver.
-
You want the plunger to sit
in the middle of the bolt guide, about 1.25"
from the end of the barrel.
-
The inside and outside
surface of the receiver may be quite hard,
you must be careful not to break the tap!
-
This usually happens just as
the tap begins to show inside the receiver.
-
Screw the plunger in until
the threaded body just touches the bolt,
then back it off 1/8 of a turn.

The
MIT machinist reference describes tapping as: |
|
 |
A tap has cutting edges to cut
the threads and straight flutes to allow chips
to be expelled. The end of the tap is tapered
slightly to help the tap get started. Taps are
hard and brittle so you should be careful
working with them (try not to drop them or force
them into a hole when stuck). Be sure that the
hole you drilled is the correct size for the tap
you're using or it may break inside.
Put the tap in place and apply moderate pressure
as you turn the tap. It's good practice to back
the tap up a bit for every quarter turn of
thread you cut.

Modifications to Enfield
Bolt Head and Extractor |
|
Grind a small 45° angle on the
left side of the bolt head to depress the
ejector plunger when the bolt is pushed forward.
This also creates a space for the ejector pin to
get behind the cartridge case when the bolt is
pulled back.
Grind off just enough to depress
the plunger without blocking the bolt. Do not
force the bolt past the plunger, this can damage
the ejector pin.
Carefully grind the end of the extractor flat to
clear the end of the barrel. You want to end up
with just enough space to clear the end of the
barrel. This is usually about .055" from the
flat at the back of the extractor. You need to
relieve the underside of the extractor arm so
that it will put sufficient pressure on the case
rim. Grind it to .055" just where it contacts
the bolt head. |

Headspace the New Barrel |
-
Thoroughly clean the
receiver, particularly the threads where
your new barrel will screw in. If necessary
they can be "chased" with a 1-14 tap.
-
Remove the extractor from
the bolt head. You will have to modify it
later.
-
Replace the bolt head on the
bolt, put the bolt assembly back in the
receiver, and close it all the way.
-
Insert a dummy round or "GO"
gauge into the barrel chamber.
-
Screw the barrel and it's
lock ring into the receiver until it is
stopped by the bolt face.
-
Cycle the bolt to ensure
that the dummy round or gauge is fully
seated in the bolt face and chamber. If the
fit is now loose, tighten the barrel as
above and repeat the check.
-
Mark the barrel and receiver
with a "Witness mark" for reference.
-
Remove the dummy round or
"Go" gauge.
-
Unscrew the barrel 1/8 to
1/4 of a turn.
-
Insert a "No-Go" gauge into
the chamber and try to close the bolt.
A. If the bolt will not
quite close your headspace is OK. Make a new
witness mark for final assembly.
B. If the bolt does fully
close your headspace is too great, you need
to run the barrel into the action a little
more. Repeat steps 5-10 until headspace is
correct.
-
Once headspace is correct
remove the barrel and lock ring, add a drop
of "Blue" Lock-Tite® to the threads.
-
Using your witness marks,
screw the barrel into the receiver until it
has the same headspace as before. Quickly
check your headspace, before the Lock-Tite®
sets up.
-
Put a drop of "Blue" Lock-Tite®
on the thread; tighten the lock ring against
the receiver face with an AR-15 stock
wrench. If you are not satisfied with the
location of the lock ring's slot, you may
careful grind the back side down a little at
a time until the slot rotates below the line
of the stock. You should check these steps
before using Lock-Tite®. This is why trial
fitting of all components is a good idea.
-
Now you may assemble the
rest of the gun.

Finally Assembly |
-
Your barrel and headspace
should already have been set up, checked,
and finalized.
-
Your extractor and ejector
modifications and installation should
already be complete.
-
You may now put the action
back into the stock.
-
Loosen the two alien screw
that hold the magazine adaptor into the
magazine catch.
-
Push the .45 adaptor body
firmly into the Enfield receiver until it
stops. It should be resting against the flat
surfaces machined into the bottom of the
bolt guide.
-
Push the adaptor catch up
until the bottom edge passes the original
Enfield magazine catch.
-
Now push it down until it is
stopped by the original Enfield magazine
catch. Tighten the locking screws.
-
Remove the adaptor body,
push it back in like an original magazine.
If your adjustment is correct it will now be
a firm fit in the receiver.
-
Verify that the adaptor is
secured by the latch, it should not be able
to come out without pushing on the Enfield
magazine release lever.
-
Insert an empty Colt® 1911
type magazine into the adaptor. It should
fit and latch with a firm upward push.
-
You should not need to
modify your stock or trigger guard. If you
have an exceptionally tight trigger guard it
may prevent the latch from moving enough to
release the magazine. The catch is stainless
steel, you may grind a little metal away
from the outside top edge to gain more
movement. When properly fitted the magazine
should be a "Drop-Free" fit when the lower
end of the lever is pushed in.
-
Do not force the magazine
into place, the first few times the magazine
is inserted it may be necessary to slightly
release the catch. Once the parts have been
operated a few times the magazine should
automatically push the catch out until it
latches in the magazine retaining notch.

Range Report |
|
Lately it is like I have been living during the time of
Noah and the great flood. It rains for weeks on end and
this is usually accompanied by wind that peeks between
65 mph and 85 mph. Every time I would get ready to go to
the range this is the weather I faced. Then once the
weather cleared up it would take days for the ground to
dry out just enough so my dainty size fourteen clod
hoppers did not sink several feet into the mud traps as
I tried to walk back and fourth to my targets. Finally
it dried out enough for a visit to the range. I was
starting to get withdrawal symptoms.
I had installed an
Advanced Technology Inc. (ATI) Enfield No. 4 Scope
Mount before heading out. A couple of comments on this
mount: It is made of aluminum and it is very easy to
strip out the threads while inserting the supplied locking
screws. That being said...if you are careful it can be
installed and is a very serviceable scope mount. It is a
weaver style rail. This means some Picatinny style
scope rings may not fit properly. My EOTech 512 fit just
fine as pictured in figure 38 below. I found though that
Richard was correct when he commented that the EOTech
looked pretty high for a proper cheek weld. I have a big
ol' head, but not even my big head could frame a good
enough sight
picture. I went to my backup scope, an AimPoint CompML2
as pictured in figure 39. The CompML2 mount did not fit
the weaver style mount so I had to enlarge the rail
slots in the mount. This was easily accomplished by
filing a little bit at a time until the mount fit
snuggly and locked into place. |

Operation |
-
Depress the stainless right
side lever to remove the 1911 magazine from
the Enfield adaptor.
-
While the lever is
depressed, pull the magazine down until it
is clear of the adaptor.
-
Push rounds into the 1911
magazine from the front edge and downward at
the same time until full. Many magazines
work best with one round less than full
capacity.
-
Insert the loaded magazine
into the bottom of the adaptor, push up
until it latches in place.
-
Push the bolt smartly
forward in a single motion; push the handle
down to lock the action.
-
The action is now cocked and
ready to fire. If you do not intend to shoot
immediately, engage the safety by rotating

Barrel Break-in, Hints for
Accuracy |
Your Enfield .45 kit comes with an air-gauged
match grade Montana Rifleman® precision barrel.
In order to get the best accuracy and longest
life from it we recommend that you "Season" the
barrel before extensive shooting. This is really
an easy task, it just takes a little patience.
After the gun is fully assembled and all
functions have been double checked:
- Load the magazine with ONE round.
- Chamber and fire ONE round, extract the
spent case, remove the magazine, and clean
the bore.
- Examine the primer of the first couple
of rounds to verify that the firing pin does
not protrude excessively.
- Repeat firing single rounds at least
five times.
- Load the magazine with FIVE rounds, fire
and extract them, remove the magazine and
clean the bore.
- Repeat at least three times.
- Your barrel is now "seasoned" and ready
to use normally. It is a precision
instrument, cleaning after every shooting
session, or occasionally while shooting if
you shoot a lot, will help to maintain it's
accuracy for many years.

Maintenance |
- Your Enfield .45 kit was manufactured
using the best possible quality
materials and components.
- Your completed gun is a precision
instrument.
- Please follow standard cleaning
practices after each session of shooting.
- The .45 barrel is carbon steel, it is
rifled to air gauged match quality.
- The exterior is a black parkerized
finish unless you have applied an alternate
finish. It should be lightly oiled after
cleaning.
- Cleaning from the breech end will
protect the muzzle crown.
- The magazine adaptor is hard coat
anodized aluminum; it is scratch resistant,
but not scratch proof. It may be cleaned
with normal gun cleaning solvents, or mild
soap and water, then dried with a soft
cloth.
- The magazine catch is stainless steel;
it is rust resistant but not rust proof. A
light coat of gun oil is recommended.
- The small coil spring under the magazine
latch should be treated to an occasional
drop of oil.
- The magazine catch should not normally
be removed for any reason, it can be
replaced if necessary by driving out the
stainless 1/16" roll pin.
- The basic Enfield action and bore should
be cleaned in the same manner as any other
bolt action rifle.
- Most Enfields have a black parkerized
finish, some may have all or part of the
action overlaid with a coat of black paint.
- Parkerized surfaces should be treated
with a light coat of gun oil after cleaning.

I loaded up with a couple boxes of CCI
Blazer .45 (ACP) Auto 230 Grain FMJ ammo. I like this ammo
because it keeps the cheap and lazy side of me happy.
This is the side the usually wins out because I usually
am too busy and do not
feel like going into the garage and ramping up to
reload. It only runs about $10 to $12 per fifty
cartridge box and it is actually pretty accurate for
inexpensive target or
plinking ammo. I used a chrono because I wanted to see
what feet per second (fps) the rounds were coming out of
a 16.5 inch length barrel. CCI gives 845
fps at the muzzle of a 5 inch barrel (1911 Auto) for
this ammo. |

The recoil with the SIA carbine is almost non-existent,
it's like shooting a .22 rifle. You can hear the .45
slug whine as it arcs its way to the target, then makes
a loud thwapping sound as it breaks the paper. Overall I shot
about seventy cartridges down range with pretty
consistent accuracy. Using an optic sight was a huge
improvement over my Rhineland Arms carbine with open
iron sights. The greatest improvement I found was that
the supplied 1911 magazine slid in and locked in place
every single time. You did not have to feed the magazine
in and then pull it back until it locked into place.
Feeding was always positive and functioned without flaw
as compared to my experience with the Rhineland Arms
model. Extraction was good with a few cases not ejecting
fully but overall a huge improvement over the prior
model.
The SIA .45 ACP carbine is lightweight, accurate and
an attention getter at the range. A real unique little
firearm that would make a great addition to anyone's
collection.
Prices, services, and product availability can be

Note: You may have noticed we have stopped
doing two things lately on Surplusrifle.com. We have
stopped listing prices and giving direct links to the
products on a vendor's web site. The reason for this is
that we publish articles that stay up forever. We have
found two constants in the world of the Firearms on the
Internet:
Prices always change and web links are also
always changing.
Because of this we are constantly getting email from
either vendors that have been contacted by a reader
complaining about a lower price listed on
Surplusrifle.com then what they currently have listed on
their web site or we get emails about links being broken
to products on vendor's websites. I am sorry for this
change but since we now have over 5k pages on
Surplusrifle.com of information it would be a full time
job for us to constantly be retracing our steps and
testing all pricing and web links. Now we just list the
main link to the vendor's web site and no price. |
