For: MagPul PTS 120rd M4/M16 Mid Capacity AEG Magazine (P-Mag/M-Version/BLK)Product Information:
This mag is incredible, the thing just won't break. I've had 2 of them for almost 2 years now, I've left the spring compressed for a month or so, still feeds fine (my Scar fires almost 20bps), slammed it around, no marks, I even lost a small part that helps keep the bottom plate in place, still rock solid. The build quality is incredible as you would expect from a company that makes actual firearms. My only problem is the price but, with how good these things are it is worth it, you just can't go wrong with this mag. Also, other companies sell p-mags and are significantly more expensive, why not just get one from the people who actually make the real deal.
fit (nice and tight but always slides in easily)
it could go on and on
the price, but like i said, it doesn't really matter with a product this good
