The Tyrant Designs Universal Fit Compensator 9mm, or the "Uni-Comp, has a unique, two piece, design that installs securely without the need for set screws or any attachment methods. The walls within the compensator help to break the flow of gasses which are then re-directed to two chambers located at the bottom of the compensator. This entire process will reduce muzzle rise and recoil. This compensator is compatible with ½-28 threaded barrels. It works with a variety of brands such as Glock, Sig Sauer, CZ, Walther, and more!
