Looking for an budget minded mount for an Aimpoint that will let it co-witness with the irons but won't rattle loose or lose its zero . I know Larue makes one and I am sure I could figure out a dozen other ways to spend 100 bucks or more on this but being unemployed at present I am just trying to figure out something that won't break the bank . I have a flat top AR with standard fron sight and a clamp on A2 style rear sight without carry handle .
