      Outstanding quality

      Posted by Kevin K on Feb 23rd 2025

      I have tried several other extensions for other guns and they are plastic crap...this not only works well, but actually makes the gun look cooler, like it is a factory fit.

      +7 PSA rock extension

      Posted by Paul on Nov 10th 2024

      Works perfect. Definitely not made cheap. For those who said they dont give instructions on how to assemble…. Its on the back of the tag. Only tip i have is do not install this plate on a new mag. The spring will get caught everytime in the bottom leaving your bullets loose in the mag. Use a mag that has been broken in for best results. Switched plates onto older mag ran like a charm everytime.

      +7 mag extension. 7 more pews per mag!

      Posted by Jason W on Sep 30th 2024

      I have not gone to the range, but I love the extra pew-pews! It is perfect when you have them at the range or in home defense. Really can't use them for EDC. I bought 10 mags from PSA. I have 2 right now, and I have been thinking about getting 2 more of them. Good quality product.
