Not sure if I should post this here or elsewhere. I recently acquired a Plainfield Machinery M1 Carbine. The previous owner had removed the rear sight assembly to install a scope mount. I purchased a adjustable rear sight assembly off the EE and have found that the sight just slides into the rear dovetail with no resistance at all. I have read about “peening” the top of the dovetail on the receiver but I’m a tad nervous about doing that as it looks like some small chips of metal are already missing from the top of the dovetail. Is there any other way to affix the rear sight into the dovetail? Loctite? Epoxy? Anything that could be reversed if I ever needed/wanted to remove the rear sight?
