If the upper band is stuck in place use a
wooden dowel to tap it forward. Otherwise
slide the upper band forward.
Note: We do not cover the removal of
either the front or rear sight assemblies so
you will not be able to remove the upper or
lower band from the rifle's barrel on the
1903, 1903A1, and the 03A3.
|
 |
7)
On 1903 rifles (1903 and 1903A1) you can
loosen and remove the rear lower band screw
and lower band swivel. 03A3 and
03A4 rifles have a tapered rear lower band
screw that should not be removed, but only
loosened.
|
 |
8)
Depress lower band spring and slide the
lower band forward. |
 |
9)
Slide the hand guard forward and off of the
barrel. If there are clip springs on
the bottom of the hand guard, do not attempt
to remove them.

removable hand guard ring that can be slide
forward as well. |

stamped metal trigger guard (with
non-removable floor plate) being removed
from the rifle. |
 |
20) Figure 19 shows the 03A3 and 03A4
magazine spring and follower being removed
from the rifle. Note that the magazine
spring just rests against the bottom of the
trigger guard/floor plate and is not
attached. The 1903 and 1903A1 instructions
above for disassembling the follower and
magazine spring are the same with the 03A3
and 03A4 rifles. |
 |
21) Separate the barrel and receiver from
the stock. |
 |
22) Loosen the cut-off screw until it
disengages the spindle. |

and pull the cut-off spindle out. |

 |
33) Separate the sear and trigger. |
 |
34) Drive out the ejector pin from the top
side. It has a slot cut into it giving the
impression it is a slotted screw. It is not,
you can turn it all day long and it will not
unscrew. |
 |
35) Remove the ejector pin. |
 |
36) Remove the ejector.
|
|
Not pictured: The bolt stop assembly is
located at that bottom of the receiver at
the front of where the sear spring meets the
bottom of the receiver. We really do
not recommend removing the bolt stop and
bolt stop spring. The pin and spring are a
single assembly. They can be removed if
necessary by inserting a small punch in the
hole in the spring and drawing it out. Note
that some 1903 and 190A1 rifles do not have
a bolt stop. |
