Magpul PMAG 20 Gen M3 300 Blackout AR-15 Magazine - 20 Round

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.

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

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

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

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.

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

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.

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.

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

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.
