Great buy!

by Chris, Verified Owner from KS, United States Written on October 18, 2025
This mag is a great buy. It's a Pmag, so you know its going to work and not have problems with the follower or spring. I got a couple of these because i wanted to double them up and use it with a super safety. I figured two of these coupled together will have less malfunctions than a drum magazine.

If you don't happen to live in a crappy commie state, buy'm up when the go on sale.
Pros:
  • reliable
  • High capacity
  • It's a Pmag
Cons:
  • None

Great addition

by Johnny, Verified Owner from KY, United States Written on February 24, 2025
Magpul has never failed me. This is a must have for doing range time in the prone position. Allows you to practice more without having to strain to see the optic while prone.

40 rnd AR mag by magpul

by Jamie, Verified Owner from PA, United States Written on September 13, 2024
None better. 10, 20,30,40 Hands down the best magazines made. I had mags that had been loaded for over a year with green tip garbage because that was all I could get during the pandemic. While changing out the rounds by firing or manually stripping them out the Magpul magazines were the only ones to perform flawlessly. Don’t put your butt on the line with cheapo ammo or mags. Buy Magpul everytime.
