  1. Does what it says! 4 Star Review

    Posted by on 5th Sep 2019

    Very nice construction does exactly what it says. The only reason, I did not give the item 5 stars is because getting the last two round in the mag seems to be close to breaking my Hulu due the pressure of the spring. {But I guess this is kind of expected) Also I did have to modify the adapter a bit to get it to fee a full magazine.

  2. Purchased 3 of these, none of them work reliably. 1 Star Review

    Purchased 3 of these mag extensions for PCC outlaw matches and USPSA. Unfortunately, I simply cannot get any of the three mag extensions to work. They will not feed reliably. They keep jamming/failure to feed. It might be a spring issue. I’ve tested them in 4 different PCC’s that take glock mags (all over mags I’ve run in them feed just fine) and none of the MBX mega’s will feed. Attached them to OEM factory glock mags. Very frustrating.
