Rock mag extension
Pretty awesome. Love it

Excellent product
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.

+7 mag extension
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.
