X1 is a tunable, high-performance compensator like no other. It combines a highly efficient asymmetrical port design along with two adjustable ports to create a compensator that will provide optimal performance based on the individual shooter. The adjustable ports counteract for the different variables that cause muzzle movement like shooting style, shooters physical stature, gun weight, barrel length and ammunition to name a few. The only way to have perfect muzzle control is to have a tunable compensator. The X1 makes this process easy with its Adjustable Port Door System which changes compensation on both the x and y axis to enable optimal muzzle control for every shooter no matter the variables. Since there are separate left-hand and right-hand models, and the ports are asymmetrical, the redirected gas path is optimized to give the shooter the maximum amount of performance and recoil reduction with less perceived blast.  Like all Ultradyne muzzle devices, a timing nut is included for easy installation.
