These mags work perfectly. Based on MagPul products, which I’ve used in the past, I expected they would be fine. They were shipped quickly and well packed. The modification keeps them within my state limits. Thank you1

Bought 15rd 300BLK and 15rd 5.56 mags. Perfect for my needs.Enough adhesive to retain the bottom plate – but no excess either externally or internally. Good stuff.

These are a lot more versatile than the 15/30 magazines. They’re shorter, so much easier to shoot prone or off the bench with a bipod or bags. Build quality is typical Magpul (excellent). Definitely recommend.

I used these 15/20 mags at the range recently. They are perfect! I have no complaints as everything worked perfectly. No wobble, no jams, only holes in paper. If you live in Colorado, this is the max number of rounds allowed in the most compact Pmag possible. Shipping didn’t take too long at all. I’m definitely ordering more soon. Also, the 20-round mag looks sweet in an AR, it makes it look like a .308 Marksman Rifle.
