What does a compensator on its own accomplish on an air gun?
There are a few different types of air gun compensators, but they all serve the same purpose: to help keep the muzzle stable and reduce muzzle rise. Most air guns have some form of compensator built into the design to counteract the recoil from firing.
The compensator is usually a plastic or metal device that sticks out from the end of the barrel and has one or more holes in it. The holes allow air to escape from the barrel as the bullet leaves, which helps to stabilize the muzzle and reduce muzzle rise. Some compensators also have ports on the top that help vent gases upward, which further helps reduce felt recoil and muzzle rise. compensated guns can be extremely effective for target shooting and plinking, as well as for hunting small game.
