      Excellent product

      Posted by william on Mar 15th 2024

      Fit and finish is solid, easy to install, seems well made. Would be nice if it came with a small amount of thread locker and disassembly directions. Tip: push down on psa logo on your factory mag plate to remove it.

      This is a 3 minute upgrade that is totally worth it. I now am sporting 30 rounds. In a pistol. God Bless America!

      +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.

      Overall product review

      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.
