Compatible with Marui / WE / KJ G17 (Gen 3) series and Umarex G17 (Gen 4).
This is a compensator that is installed using the underrail of the frame, and the actual product allows some of the projectile gas to escape from the top of the block, which has the effect of suppressing muzzle jump. It is also used to prevent the slide from being pushed back and being unable to fire when the muzzle hits an obstacle or target.
The kit has an underrail at the bottom, so you can also attach a flashlight!
