The PMAG 20 300 B GEN M3 AR-15 Magazine is a dedicated for rifles chambered in 300 Blackout. Optimized for 300 AAC Blackout, the PMAG 20 300 B features a distinct rib design and smoother upper texture to set them apart from other PMAGs for quick visual and tactile identification. This AR mag is easy to disassemble and clean for regular maintenance and won't fail you in the field. While standard AR-15 magazines may be used for this cartridge, the potential danger exists to chamber and fire a 300 Blackout round in a 5.56 NATO chamber with catastrophic results.

Features:
  • 20 Rounds
  • Dedicated 300 Blackout magazine
  • Impact and crush resistant polymer construction
  • Optimized internal geometry for 300 BLK
  • Anti-tilt, self-lubricating follower
  • Long life USGI-SPEC stainless steel spring
  • Over-travel insertion stop
  • Distinct rib design and smoother upper texture for easy identification
  • Aggressive front and rear texture

Love the dedicated 300 BLK Mag

by -

I have 2 and find they are easier to load than my 5.56 mag's. Not a huge deal but worth the small investment.

great mags

by

I bought these to replace my 30 rounders. I found these are a better balance of weight and size.

great magazines

by

these 20 round 300BO mags work for supersonic and subsonics. These are the perfect balance of weight for a pistol or sbr.

nice mags

by

great size and weight for a pistol. I use these at the range and personal carry. shot everything from 110gr to 220gr ammo without a hang up

good product

by -

I am well pleased with these 20rd. mags I wish these were available when I bought the 30 rounders. Salesperson was most helpful on my purchase.

good product

by -

I like the 20rd mags better than 30's I have both. Magpul makes good products.

Works nice

by -

Works great in the 300Blk. Yes you can use the 5.56mm mags in the 300, however I prefer to use these, that are designed for the 300. I wished they had the windows, due time.

Works with heavy supers

by -

My 223/556 mags worked fine with light 300blackout supers but didn't feed the 210gr and 220gr worth crap. These 300blackout mags feed the heavy subs 100% reliably so far.

Only run Magpul PMAG

by -

Easy to load rounds. No problems with cycling. Follower holds bolt open when empty. High quality, great workmanship. Stock up!

Love the 20 Pmag

by

Excellent product. Picked up 4 more today to add to my bullpen. The 300 20 mags are the perfect size for on the move, plinking at the range & harvesting protein. I have shot both subs & supers with no issues. Highly recommend.
