great product, does what it claims

by Pauly2Tusks, Verified Owner from MT, United States Written on December 31, 2023
The elimination of the crush washer is why I went with this brand over others. Wish the timing nut was longer and eliminated the washer placeholder for the front sight. Spendy but less than half the price of the Hellfire.
Would recommend: Yes

Best Compensator

by Nico, from NY, United States Written on April 2, 2019
Eliminates all if any recoil especially on a .223/5.56 smith & wesson sport II. It's very easy to install without any crush washers. A must get and you will def thank me later. I would include a photo of my setup if it was possible.
