I have an M1 carbine that has the rear sight adjustment moving under recoil is there a way to tighten it up to set the elevation and have it stay in that setting. I have this rear sight:

The adjustable Carbine sights were permanently assembled and there was no repair method. Defective sights were simply replaced. Original milled or stamped adjustable sights are still available, so just cut to the chase and buy a new one. To install without a sight pusher, carefully use a heavy brass drift placed on the actual dovetail part of the sight, NOT on the upper part. Originally the new sight was cranked over to the left and a rounded center punch was used to move some metal to secure it. The idea is to move a little divot of metal, not to put in a punch mark. The receiver usually has a small cut to move metal into. These days a simpler and less chancy method is to degrease the sight dovetail and the receiver dovetail and use Loctite. When staking Carbine sights there's a risk of chipping or even cracking the receive. |

It is possible but difficult to remove the aperture on the TII Carbine rear sight. It has been a while, but I believe the aperture has a spring and a bearing in the bottom to engage with the cuts in the base. That can be gunked up. IIRC, it comes out the front and you run the risk of breaking the base removing it. It'd be ugly, but you may also be able to deepen the detents in the sight base as well. |
