Amend2 polymer 6.5 grendel mags

[PNW_Grendel]

I have about 50 of the AR mags, and about 20 glock mags that I use in uspsa and other competitive shooting sports, and never have I had a single issue, except for sticky follower on one glock mag when it got dirty. Not sure what the heck you are doing to break them, but they are a good mag. They do offer lifetime warrenty and will replace them if you break them.

I also have a bunch of these mags, 15 of them, all have been reliable as well. I run my stuff pretty hard as well, plenty of training and drills, never had an issue. Can't wait till they release the grendel mags.
