Most Helpful Positive Review Perfect magazine for 300 Blackout SUBSONIC ammo
I bought the different brand if magazines before this one and they all didn't feed the 220 grain subsonic ammo for my 300 BO. This magazine not only feeds the ammo but it was also very easy to load by hand. Great quality and solved my misfeeding issue that I was experiencing with other brands and ev...

Excellent 300 blk mags

by Alex, Verified Owner from TX, United States Written on October 4, 2025
Very good sturdy constriction. Cycling is great, not even a single issue. Lightweight, you can clearly see rounds. The top part is made of steel. I am not sure if it is entirely friendly with aluminum in the lower receiver (much softer material) but I have not noticed any issues…Five stars at this point
Best Used for:

Best magazines on the market.

by Ratrod79, Verified Owner from TX, United States Written on September 7, 2025
These are the best mags out there, with the metal jaws, you don’t have to worry about leaving them in a hot vehicle or any deformation. I never had a failure with them, they are my go to mags, better the the P mags in my opinion.

Only 29 usable rounds YMMV

by Lucky, Verified Owner from FL, United States Written on April 1, 2025
I bought 3 of these mags specifically for use with subsonic rounds and overall I feel they are good quality build and materials. In both my Sugar Weasel and Palmetto State 300blk rifles none of them lock when loaded with 30 rounds, but they do lock with 29 rounds. I tried PMAG 300 Gen 2 and it also had the same issue. A PMAG 556 mag locked fine with 30 super rounds. I won’t ding the brand as the issue seems to be caused by the larger size of dedicated 300blk mags.
Pros:
  • Feels Solid and good translunceny
Cons:
  • Can not lock with 30 rounds
Best Used for:
  • 300 Subsonic
Would recommend: Yes
