Bad production lot! - Mission First Tactical 10 RD Extreme Duty Polymer 7.62 x 51 NATO .308 Winchester AR10 SR25/M110 Magazine

I bought 2 of these mags in brown so i could easily identify my 22-250 ammo. Well as the saying goes, "you get what you pay for". The lock up indent is not in the correct spot on the mag! its off a slight amount so they dont lock up in the rifle. I tried on other ARs and the same problem exist. Rather than send back, I got out my exacto knife and my dremmel tool and got to work. I removed my lockup bar from my AR and saw how far off the indent was on the mags. With some careful work I was able to save the 2 mags from a return. What a pain in the a** it was. OPTICS PLANNET NEEDS TO PULL THE MAGS AND RETURN THEM TO MANUFACTURER.
