.300 Blackout vs. 5.56 NATO Disclaimer
While .300 AAC Blackout (also known as 300 BLK) and 5.56 NATO cartridges are designed for use in AR-style rifles, they are not interchangeable and must never be confused or cross-loaded. Firing a .300 Blackout round in a 5.56 NATO chamber can result in catastrophic failure, as the larger diameter of the .300 BLK bullet may not fit properly in the 5.56 barrel—leading to a barrel obstruction and potentially serious injury or damage.
Though both cartridges can be used with similar bolt carrier groups and magazines, it is critical that shooters take extreme care when switching between calibers, especially when using rifles with interchangeable uppers or multi-caliber setups.
Always verify the ammunition you are loading matches the markings on your barrel and upper receiver. Mixing up .300 Blackout and 5.56 NATO can lead to dangerous malfunctions, injury, or death. When in doubt, double-check.

30 RD exd 5.56 mag
I've never used this brand before. The mag seems well built. I havearound 200 rds through it so far with no issues at all. I will be buying more in the future.

Solid Mag
Have 8 of these, been using them for over a year now in a Ruger AR556 with zero issue. Seat firm every time, no loose spring noises or rattles. Rugged, I dropped a few empties on the ground at the run n gun range and reload with nothing worse than just a couple light scuffs, no big deal. I personally like the smooth finish with just a few finger bumps, just looks slick to me. Never had any grip issues. One thing to note: Although they will HOLD 31 rounds, they will not LOAD 31 rounds. You have to load 30 to get it to seat.

great, durable mags
These are really stiff and have worked well. I like these much better than the 1st Gen Mission First magazines.

Respect!!
I purchased 3 MFT standard mags a little less than a year ago. I recently checked my B.O.B. and found all 3 were spitting rounds due to a bad batch of mags. I emailed MFT letting them know and within a week they replaced them with extreme duty mags!! I will always buy from MFT from now on!!

YOU GUYS ROCK!
I have a private range and am able to shoot A LOT. I have several standard mags and several extreme duty mags. No failures, no issues, complete confidence in my magazines. Had a QUESTION ( not a FAILURE ) for MFT and their Customer Service was outstanding. Highly recommended

Better than magpul easily.
Absolutely the best magazines I've used. Extremely solid, no spreading feed lips. Easiest to actually load 30 rounds and insert on a closed bolt. It feels like it's downloaded to 28. Drops free smoothly. Zero complaints, and M.F.T has the best customer service experience I've ever felt with. Magpul magazines don't even exist anymore in my opinion.

Better than PMAG? Absolutely!
Tested 3 of these mags throughout a 2-day rifle certification course. 1000+ rounds in extreme heat without a snag or misfeed. I intentionally left them in direct sunlight to see if I could soften them up, but they held up like a champ. These fit my rifles better than the Gen3 PMAGs.

Awesome mags and even better customer service!
Hands down our favorite polymer mag on the team. Super durable with excellent feeding. They have now been carried by 3x of our guys on SOF deployments with no issues whatsoever. They are so sexy that Kuwaiti customs confiscated two as I passed through on a flight. Upon hearing this, the MFT team sent me 3 more.
