I see in a lot of AR images that people are numbering their mags. Why is this? To keep them in a rotation so that they wear consistently?

Yes and to identify them from one another.  Sometimes certain mags can work best in some rifles.  Also may use even/odd mags for certain loads, etc.  Just another quirk for the OCD with BRD.

 My AR rifles come in two caliber, 5.56mm and 6.8mm.  The former uses Magpul and Lancer mags exclusively.  They are bulletproof and are unlikely to ever wear out, so no need to number them.

My 6.8 mags are all steel, with lips tweaked so the bullet tips point slightly upward at the top position.  5 of these are identical ASC 15 rounders.  I numbered them with paint on the right side so if one of them starts to malfunction, I will be able to keep track of it while I diagnose and fix the problem, or scrap it.  - CW

Tons of reasons including all the above. Guys who shoot comps or take courses can't account for mags when changing them, so after the course of fire you know who's is who's. If you're having a odd feeding issue you can track mags to help in the process of elimination. Leave one at your local range and next time you see your mark on it, kindly ask for it back.

And because operator bro.

To keep track of them

When im at the range and I do drills I have 4 mags, 1 in rifle 3 on check. As I move I will drop mags, its nice to identify which are yours and be able to put them right back in place.

I do it because if one fucks up, I want to know which one it is.

This. I know which one is having issues.  I also will put an ID on mine so I know which one is mine if I'm in a class or lots of mags hit the ground from multiple shooters.

Also to get my own worn out trash back when shooting matches, and drills.

Interestingly, my M1A has numerous mags it prefers just in the accuracy dept.

Those mags will consistently shoot smaller groups over others.

That is the reason I do it. If you find a bad one, weak springs.

For the same reason I number my arrows.

and shit can it after it has been identified.  I have zero issue buying another $12 pmag that I will trust with my life.....

All good reasons.  One mentioned but perhaps deserving of expanding upon is different loads.

Your rifle is going to be sighted in for a particular load.  If that is a long range load, like a 77 grain SMK, or 70 grain Berger VLD, you don't want to shove in a mag full of 55 grain M193 that would be terribly inaccurate at long range.  Nor would you want to put the 77 SMK load magazine into the rifle in place of your 64 grain Gold Dots or 62 grain Barnes TSX loads that you depend upon for home defense.  At home defense distances the difference is zero would be irrelevant, but ammo choice highly relevant.

Numbering the mags in a manner that makes sense to you prevents this.  The ammo is going to be all loaded to close to the same over all cartridge length, so visually, it would be hard to separate out the loads.

Other benefits are well-identified above.

Thats fine and dandy when AR mags are $8-12, but for all my more expensive pistol mags I will usually try to see whats wrong and fix it instead of tossing it. Often times its just new springs or something minor, anything major like a bent feedlip and its scrap.

I use a paint pen and write my initials in a unique format to identify as mine. I don't number. If one messes up, put tape on it or put a spent case in backwards for later.

Too much work to number them and use certain ones at certain times.

This, this right here.




I had a buddy who ran a match with me that didn't have his mags marked. He had issues with one pmag, and couldn't identify the particular one because it was not numbered/labeled (the mag caused problems twice, during two different strings of fire). He had all the same color (tan) pmags. Luckily, after the second time, he tossed me the mag and I segregated it for him.

i dont number mine but i do have a set of dedicated range mags that have colored tape around the bottom. over the course of 25 years of constant use, loading, shooting, being dropped, reloaded and stored loaded, i am down to about 15 now.

most of my attrition was due to broken welds and cracked feed-lips. seems like once the back of the mag starts to spread apart, feeding issue ensure. i've also had widened feed lips cause rounds to jump out upon insertion with an open bolt.

I know we have done beat the horse to death & buried it talking about if you should keep them
loaded or not for long periods of time,,,,, BUT it also helps me keep up with which ones I need to shoot next.
I use all P-Mags for everything except for 3 metal ones so I don't worry about it but I do rotate
them out just because I am DUMB!! lol Take care & have a great night, Mark
