Most Helpful Positive Review FAB Defense 10 round mag
Was a bit disappointed with the mag. The mag did not want to seat properly without really putting a lot of force on it. Needed to modify it a bit to fix the problem. The quality of the mag is good. Doesn't feel cheap and flimsy like some I have. Would be five stars if it wasn't for the issue with not wanting to seat properly.

Hard to engage

by JS, Verified Owner from TX, United States Written on January 22, 2025
Purchased for using a short 10rnd mag while bench resting / sighting in new scope on Radical 300BLK.
While no chambering or stove-piping issues thru initial use, this mag was hard to get to engage the catch when inserted into the well. Further, the last-round hold open doesn't occur. Last, it rattles more than the Lancer 20rnd mags also used.
Pros:
  • ammo cycles as expected
Cons:
  • last-round hold open doesnt occur
Would recommend: No

Takes a bit of a slap to engage.

I found it to take a bit more slap to seat than my metal mags or Pmags

pew pew all day long

by Rocklau, Verified Owner from CA, United States Written on September 27, 2024
I live in a state where I needed these, and the cost was crazy good, so I took the shot (literally and figuratively) at these mags and wasn't disappointed. Hard cased and fed nicely.
