If I can rate more stars I would.

Don't even bother modifying a normal pmag, these are worth the price for its specific caliber. Looks and feels different. If you're OCD like I am you'll end up getting these just because they say 300 blackout.
Great product...now I just wish they would make a 20rd version.

Had feeding issue with an AR of mine using 220gr Subsonic loads. Using Lancer and standard 5.56 Magpul mags I could only load about 3 in the mag, any more and I would have feeding issues. I tried one of these mags out of curiosity...compared to a standard 5.56 Pmag there doesn't appear to be much difference...a small follower change that to the eye did not appear to change the bullets' orientation. Well, I loaded up more than 10 in the magazine and tried it...seems to work perfectly now. Maybe the small changes Magpul made did the trick.

Never really had a lot of problems with 223 mags. Some small problems like feeding to mag capacity. I like the ease of loading and unloading. Magpul does it again, too bad they don’t make 7.62. I am sure they would work as well as RZE and be lighter on the wallet...

I was using standard 55.6/223 AR mags in my 300 BLKOUT but recently switched out my mags to these 300 Blackout mags. I still use the standard AR mags in my 55.6/223, but I now only use the 300 mags in my BLKOUT. And it does make a difference.
It’s a PMag. It works.

A must-have for long, round-nose, subsonic projectiles (like the Noveske/Nosler 220 grain offerings) that can cause binding in standard GI/PMags. Works perfectly. Tactile distinction from standard PMags an added bonus.
Easy to tell the difference.

Another great magazine by Magpul. The only difference between this magazine and the standard P mag is the texture on the outside. It was added to be able to tell the difference between a magazine loaded with 5.56/.223 and one loaded with 300 blackout. are used to put green electrical tape around the magazines loaded with 300 blackout. I no longer have to do that.
