      +7 mag extension

      Posted by Brett on Feb 4th 2024

      It was a flawless fit. However some small packs of temporary loctite would be nice. Also a video that shows the breakdown of the PSA mag prior to installation would also help tremendously.. however now I figured it out it's awesome. Good job guys. Maybe offer new colors either vinyl or anonizing seeing how not everybody's Rock is black.

      Install was a breeze. Out only took a couple of minutes. After install it fits all 30rds and it looks/feels amazing!

      Overall product review

      Posted by QuinBodis on Dec 29th 2023

      I didn’t expect for this mag extension to be as perfect as it is! Even though I was only able to fit an extra 6 rounds in my PSA 5.7 Rock mag, I have no complaints.

      bought a bunch

      Posted by DT on Dec 7th 2023

      PSA rock is a nice gun. this lets you add more to a nice gun. Win/Win build quality looks good.. so far function has been good... i can't speak to longevity of the mag extensions or the rock. as i havent owned either for a very longtime. would buy again.. but at this point i got all my mags covered and i have plenty of mags.
