One Outstanding Magazine!

by -

They They fed 5.56 and 300 Blk without issue. I have used polymer mags for the past ten years. At this point, I'm going back to what works. Metal mags from now on. I was very pleased with the quality and construction of these mags. They were also lighter that I expected. I will be purchasing more in the future. Just a quick shout out... PA is my favorite company in this industry!

Magpul Has Nothing On These Magazine's!!!

by -

Is the best magazine I have used yet. ZERO issue's, feeds everytime, and the anti tilt flowers are the real ones. Not the so called anti tilt ones. The mag is a tad heavier then aluminum but that is to be expected being stainless steel. The weld points are welded on phenomenal well. I have bought 30 of these mags so far. And the reason is upon my 1st purchase I really abused the mag. Actually at one point throwing it into a concrete floor trying to break it. And it is still going strong. Inserts no problem, ejects no problem, feeds no problem. I sold all my magpul mags after this test. I would highly recommend stocking up on these mags!!! PA (Primary Arms) is always my 1st stop to shop!! ALWAYS!!

Hands down these are the best mags out there. I would trust my life with them. These steel mags are built like a tank. I use these for my duty rifles.
