USA – -(Ammoland.com)- What would a trip to the range or idle chat at the local gun store be without talking about the best magazine for your AR-15?
Name brands get tossed around worse than a Ford vs. Chevy argument, almost with the mysterious faith of the Glock vs. 1911 debate. During the Obama years, it seemed like there was a new manufacturer every month.
Times were easy then, everyone was afraid that fresh 30-rounder they saw on the shelf might be the last mag they’d ever see on a shelf and we gobbled them up. Now we all have dozens. Some of AR magazines work, others not so well. One AR rifle magazine that seems to work in one rifle doesn’t so work so well in another. I decided to take a look at the why without worrying about the springs or followers which are easily replaced.
While serving in the Army, one of the significant concerns were the feed lips on our aluminum magazines. Over-insertion, dropping them, shoving into a ruck or pouch, and even just time seemed to change the angle of the feed lips, and thereby the way rounds would strip. The now-lost art involved using a stripper-clip guide to bend them back into place carefully.
Who’s AR Magazines?
AR Magazines by the Numbers
The first measurements made were in the mag catch area. I argue that these measures can influence the seated height and angle of the magazine, depending on your magazine catch. One would expect that these numbers would all be similar, but they weren’t. I can’t say which is best for your rifle, and in fact, they may all work, but it was an interesting finding.
With the statics out of the way, I wanted to know how much these AR rifle magazines flexed when loaded. As mentioned earlier feed-lip width can influence a lot, so what happens to that measurement between empty and 50% load? What about 24 hours later, 48 hours later, and one week later? Can we store AR magazine loaded without effecting performance? This is where differences began to show. As a precursor, I measured feed-lip width before loading and immediately after a 50% load. Some of the changes were unexpected.
So what Magzine won? That depends on what you’re looking for. From this simple experiment, it appears that Mission First Tactical, Daniel Defense, 3rd Generation PMAG, and American Tactical are sure bets for maintaining geometry when stored loaded with ammo. All of these magazines have run well in my rifles except for the Master Molder and Daniel Defense.
Once again this is a sample size of one and is intended to serve as an informative study, not a definitive judgment.
