      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.

      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.

      Rock 5.7 mag extension

      Posted by Chris D on Nov 1st 2023

      This is a quality item. Fits around the frame and fits the magazine nicely. Quick and easy to install. I was able to easily get all 30 rounds in the magazine. I would definitely recommend this mag extension and the company. Super fast shipping also. My only complaint is that it's a little on the expense side as far as extensions go, but after seeing the quality of the extension I can see why it's priced that way.

      The product is very well made; good quality and fits perfectly; easy to install. A youtube video on how to installed should be made.
