Just picked up a M1a socom 16 for Christmas. Lightly used. Looking for suggestions on a red dot optic to install using the stock rail. I’ve been looking at the Aimpoint Pro Patrol and the Holosun 507c. I have the Holosun on a Glock 19x and the Aimpoint on an Ak47. Both work well for their applications. Any new ideas that will work but not break the bank?
