DURAMAG Stainless Steel 5-Round AR-15 Magazine - 6.5 Grendel - Blue Follower

I received this magazine and without closely inspecting it I test fit it in my receiver where it promptly became stuck. I had to disassemble the magazine and rifle to remove it. Once out it was obviously and horribly out of spec. I've done business with Primary Arms for years and love giving my money to local businesses, but this time they told me to get bent because it wasn't their problem. Fine. BTW, E-Landers from LaRue work just fine.

I bought 2 of these magazines, and they have worked flawlessly. The other reviewer stated the mags got stuck in his magwell. Well, they did in mine too, but that was not the magazines fault. My magwell was not cut properly, sent it back to MFG, and the replaced my lower, no problem ever since. Mags slide right in and out freely.

The caveat is this: my mags only held 4 rounds. This was super easy to fix, by taking the spring out and using a dremel to cut 2 spring loops off the compressed spring area. Now I can fit 5, perfectly.

fits well dosn't miss a beat
