Is there a proper procedure for testing magazines?

If not, then what am I supposed to do?  Just load them up and shoot?

Good read.

Why would you only test 4 rounds at a time?

 IMHO that's a lousy way to test out a mag.  You need to know how it performs at full capacity all the way through the last round.

Eric, I certainly would agree with you. If that was the case, only 4 rounds, the 7.62x39 magazines we had would have passed that test with flying colors!!

  • Inspect the body for obvious cracks, bulges, bends, misformed parts, defective welds.  


  • Insert the mag into the mag well.  Ensure that it does not bind and that it drops free.


  • With the empty mag inserted, pull the charging handle all the way back to ensure the bolt lock is engaged by the follower.  


  • Test fire with fully loaded mag.  Repeat several times.

Armalite are pros at reliability tests though

Repeat with every mag in each rifle. I have 10 ARs so it take 280 Rnds to test one new mag.

Time consuming but the only way to make sure they will work when needed.

Take to the range and use them

if mag gives me  trouble I throw it away

NEVER had any trouble with the OLD COLT 20 rounders

I visually inspect and mark my mags to differentiate them from each other and use them to capacity several times at the range.  Mags that prove reliable at the range are marked for defensive use.  Mags that aren't completely reliable or have some sort of physical flaw get used only at the range or 3 gun matches.

I wouldn't just shoot rounds to test magazines.  What a waste of money and ammo!

Just test mags while you're having fun at the range.

I run at least 2 full loads through each mag. NO failures are tolerated; if a mag hiccups, it gets marked and I try it again with a full load. If it fails again, in the recycle bin it goes.

This in addition to the visual inspection of course.

I wouldn't necessarily disqualify a mag because of the physical condition.  I have one that has a bulged feed lip & has fed around 1000 rounds with zero problems.  Granted, some of my other mags are the defensive ones, but in a pinch I have no doubt the messed up one would function fine.

Believe it or not, there is logic behind this method.....not all encompassing, but a decent quick test.

The procedure is 4 rounds each loading and 10 cycles, which equals 40 rounds. If you buy 25 magazines, that is 1000 rounds total.

Now, if you want to go to 20 rounds or 30 rounds per each loading for testing then that equals 20 x 10 = 200 or 30 x 10 = 300.  So, if you buy 25 magazines, that is 5000 to 7500 rounds total required.   Reliability testing that way gets expensive.

Armalite's procedure should not be overlooked.
