Great magazine - Magpul Industries PMAG 7.62 AC - AICS Short Action Magazine, 5 Rounds, 7.62X51mm NATO

Bought these for a Bergara Ridgeback as it came with a 5rd Magpul AICS already. It's definitely tighter in the chamber, and the bolt rides the mag lips more than the 5rd mag it came with, but I'm guessing that may be due to how they were fabricated. This was on all 3 10rd mags. I plan to sand down the lips very slightly in order to facilitate smoother action movement, but we'll see how that goes. I'll come back and update this post if that fixes it, but I'm obviously not advocating modification of your equipment. Other than that, they're great.
