I want to put a scope on my M1A, but, I cant seem to find any good info on who makes a good mount for one. Ive narrowed down three models. First is the mount made by Springfield. They call it their Third generation mount. Second Ive found the Smith Enterprises mount, which is a copy of the old Brookfield Precision mount, and the Etreprise Arms mount which is also identical to the Smith mount. I dont know which one of these mounts are the best. Id appreciate any info any of you may have. Thank you in advance.
