Customer Ratings & Reviews
I bought this side mount to fit to a Universal made M1 Carbine with a factory drilled and tapped receiver, the same one Universal supplied a black plastic cover for. I have not been able to thread the supplied Weaver base screws, probably 8-40. I since tried every combination of screw I could get: 6 32, 6 40, 6 48, 8 32, 8 36, 8 40. many 6s thread in but are too loose to grip. Some 8s start to thread by about 1/8 truns then bind. 8 48? The threads don't look that fine. The thread feeler gage can grab about 3 threads from the outside and seems to prefer 32. I thought 8 32 would be it , but no. Unless someone can suggest something else, I am about to make thread castings to find what will work. Other than the thread issue Im having, the base holes are perfectly spaced and the part quality is very good. If the mount were steel, it could be tack welded.

Couldn't ask for better quality, fit, shipping or price. Definitely worth every penny. The M1 Carbine Scope Mount was a very easy to install. Everything lined up perfectly.

Perfect fit for Universal M1 carbine
Not just for carbines
Used for mounting a scope on a Martini Artillery carbine that's now in .22 Hornet. Perfect base for the job.
