This is definitely worth it. I got this along with the Kriss mags that have the upgraded springs, and I have officially put 1000 rounds through it without a single hiccup. Well done, guys. If you’re on the fence, don’t be. Invest in this and you’ll spare yourself the pain and agony while spending your time focusing on having fun and training.

This is a great upper. I am very happy with it. It performs perfectly. These are the guys that Know .22LR. I have put over 1000 rounds through it. Everything I have bought from BoreBuddy has been worth it.
