Thread: 308 AR magazine help?

Cheers Mark, Obviously gotta keep it legal haha but for elimination's sake I just took it out and tried with dummies, same problem:/ there's a lot of brass on the inside of the ribbed indent groove things that run up the height of the mag, could they be too tight or something, every time I cycle the bolt the rim of the cartridge being stripped catches on them, shedding brass as it goes past each, which requires a great deal of force. It's super hard to unload a mag by hand, without taking the floor plate out haha. Frustrating and baffling to the point of checking to be sure I actually had the right ammo. Dunno what else I can try
