Things I liked: Just got this for my Hammerli 850 Air Magnum. It seems a lot of people thought this was some sort of suppressor but that is not what it is for. It is a compensator. The part near the barrel has a cone shaped device known as an air stripper. This redirects the air behind the projectile away and lets projectile leave the rifle without turbulent air behind it to send it off course. It enhances accuracy, it does not reduce sound unless you wrap it and cover the holes. But that will defeat its main purpose as a compensator, muzzle brake, etc.

Things I would have changed: I do feel it is a bit pricey for what it is.

What others should know: It is not a suppressor or silencer. Have seen many people say it is just for looks. It is not, it does what it was designed to do.

Things I liked: Easy placement of Compensator on barrel. All I had to do is remove screw from front sight and move sight to the rear and retighten... attach compensator to barrel and tighten the two screws that come with the compensator. All information needed comes in the compensator package.

Things I would have changed: Nothing.

    Hello Friends, my question is if this suppressor can be used in a Walther Terrus air rifle .22. or what other options do you recommend

    • Tyler from USA:

      No, you would want something threaded 1/2"x20

  • Michael from USA asked:

    What material is it made from?
