Quality product.

I purchased this so I could shoot from a bench on bags, the 30 round would not work. Made very well and functions great.

Good fit. Good quality.

I bought these for my AR build in 204 Ruger. I have seen others comment that have had problems with the 204 feeding. If you compare these mags with mil spec steel you will see the difference in the front. I filed some material on the pmag to match the metal ones. Had no feed problems in 223 AR before the modification and none in my 204 afterwords.

Magpul Gen M3 10 rd. magazine

I purchased several of the 10 rd. Magpul gen. M3 magazines for bench rest target shooting. I've used them on three outings so far and have noticed if I load 10 rds. the 1st rd. has a tendency to jam (not load into battery). If I load 9 rds. there are no issues what so ever. I'm hoping the spring / magazine just has to break in a little more. I like the magazine for it's size to suit my bench rest style of shooting.

Required tweaking the follower

Ordered two of these 10 rounders for use in my Daniel Defense 300 Blackout. Neither mag would lock the bolt back when empty. Called Brownells and they were able to duplicate the problem. Seems there is a lateral mold line on the back of the follower that keeps the rear of the follower from returning to the full upright position. Two minutes smoothing out the mold line with a needle file and now everything works as it should. Thanks to Keith of Brownells for the fix!
