    I wouldn’t recommend this. Receive my item and it was all scratched up. The scratches didn’t affect the item function but you would think if you were getting a new item that it wouldn’t be all beat up and scratched up.

    Honestly, I was super hesitant about buying into the hype of these. But, it has completely changed how the gun shoots. I put this on a Glock 19 gen5 and it’s one of the softest, flattest shooting guns I own now. I’ll add that I hated shooting Glock until I installed this. I’ve worked with several suppressor and firearms companies in the past and shot every kind of guy imaginable. This little comp is a game-changer. I had a couple of hiccups, stovepipes, but it may need a little wearing in. The gun is brand new. But, it’s one of the best purchases I’ve made in a long time.

    I wavered between 4 and 5 stars only because the installation process is a bit involved, but this is spelled out in the instructional video, so 5 out of 5.
    Once correct spacer stack is established and the unit has Loctite applied it is solid. I did some research prior to purchase and this was one of the better reviewed comps.
    I did have a small amount of finish chip off at the top of the comp but some aluminum black and it is GTG.

    Excellent fit and finish. The compensator works excellent.
