Mag purchase

by Warpaint33, Verified Owner from KS, United States Written on November 1, 2025
I purchased 3 of these mags to tryout with my service issued rifle. One out of the 3 would not load more than 28 rounds with a maximum 30 rd capacity. I attempted to fix the issue by disabling the mag to check for issues or broken parts but none were found so I reassembled the mag to find it still only excepted 28.

Worked fine, fed everything, and gives visual feedback. No complaints.

by TswissT, Verified Owner from LA, United States Written on May 21, 2025
The FAB Defense Ultimag 30R ran flawlessly in my AR — no feeding issues, no fitment problems, just clean, consistent function. The polymer body feels solid but light, and the transparent window is a nice touch for quickly checking round count.

It locked in tight, dropped free easily, and cycled both supersonic and subsonic .300 Blackout without complaint.
