PMAG® GEN M3, 300 BLK PMAGS

**hdrolling** · 06-09-17, 10:32

Just bought my first 300 blk, BCM 9", and I was looking for a mag that would stand out a little so there is less chance to get confused with the 5.56 mags.

I see Magpul has their new PMAG® GEN M3 coming out this summer made just for 300 BLK and was wondering if anyone thought this would be enough or if there is a more preferred technique?

I was going to just use a silver marker and clearly label a normal gen II Pmag with the 300 BLK markings.

Whats is everyone using for their 300 blk, marker, tape, rubber bands, different colored mag, nothing?

I used a silver Sharpie to write 300 on mine. They also have either SUB or SUPR on them according to what ammo they're loaded with.

I use FDE mags exclusively, or FDE pulls on USGI mags. Keeps things easy.

The pmag .300 blk will be identical to 5.56 mags except for markings, yes?

• Dedicated, purpose-designed magazine for rifles chambered in 300 Blackout
• Optimized internal geometry accommodates the wide variety of bullet profiles used in 300 Blackout cartridges
• Distinct rib design provides the shooter a visual & tactile difference from any other pmag to mitigate dangerous cross-loading

I'm using a silver sharpie also. However, I'm only hunting with my 300blk and I have to use 10 round mags for that purpose. That makes it a bit easier. In the future if I change it's purpose may get the dedicated PMAG's. Even then I'll mark them somehow.
