Re: Surefire AR mags
I work for the company but I do have a lot of experience with them. Like anything we make we are constantly making improvements. My test magazine that I have been running since before we started shipping them has around 3,500 rounds through it with 1 malfunction other than locking the bolt to the rear. On my SBR's suppressed sometimes it will not lock the bolt to the rear but in all honesty my pmags will not lock the bolt to the rear all the time suppressed either.
I prefer the 60 over the 100 because of size and weight. I run a 60 all the time and it works like a charm. It is short enought that unless you are very short you can get in the prone with it and also it gives you a stable platform for shooting magazine prone. I put magpul 7.62 pull tabs on mine just to act as a buffer for when they get dropped on the ground.
You can pm me if you have any other questions.
