Things I liked:

This works great on my 850. I used electrician's tape to cover the holes and the noise is really reduced. My next door neighbors told me that they can't even hear it from their decks. Oh, I'm using it on the .22 caliber 850. It fits just fine and hasn't affected accuracy at all.

Things I liked:

My mistake, I ordered wrong product for my Umarex EBOS

Things I would have changed:

PA, please warn customers about this compensator not to use for EBOS.

What others should know:

I purchase this compensator for my Umarex EBOS. It fits well but it turned out to be dysfunctional. I contacted PA representative and they explained to me that this reticular compensator is not made /design for EBOS bb gun. I believe that it works well for pellet guns design for it.

    Things I liked:

    On the correct rifle, I guess it would be fine. But it does not fit on the Hammerli 850 with the threaded barrel. TKO Air offers this, and I highly recommend it. Makes 850 backyard quiet.

    Things I would have changed:

    Make sure you list that it DOES NOT fit on a threaded barrel.

    What others should know:

    Pyramyd air recommend TKO Air for suppressor I needed. Great company.

    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.

    Things I liked:

    Fits perfectly on my 15mm QB78D barrel. Uses 2 grub screws for secure attachment and uses metal construction at attachment point. Lightweight and well made.

    Things I would have changed:

    Perhaps have the main portion made of metal,but for my purposes its fine as is.

    What others should know:

    As stated in previous reviews,covering the holes with tape or other material (I used a carbon fiber look vinyl tape) DRAMATICALLY reduces the rifles report! I'm using it on a modified QB78D thats averaging 680fps with JSB18.1's and the report is Red Ryder quiet! Very Happy with this unit!

    Things I liked:

    It fits my Hammerli 850 perfectly. I used black electrical tape as suggested by other people and it suppresses the rifle great.

    Things I would have changed:

    Should come already insulated for this price. Wish you could install it using the front open sights mounts (they leave holes once you take it off).

    Looks are great and fits great on my hammerli 850 .22 cal.

    Things I would have changed:

    PRICE!

    What others should know:

    Doesn't really tone the sound down unless you cover up 75% or more of the holes and if you cover all of them up its as quiet as the umarex fusion! Other words super quiet!

    Things I liked:

    Fits the 850 like a glove! Does not add a noticable amount of weight once fitted. Looks very cool too.

    Things I would have changed:

    Have more than 1 set screw around to secure it to the barrel or have a better friction fit. A grove to allow the open sights would be nice to have also.

    What others should know:

    To give that tactical look or just add a different touch to your rifles this is a great option.

    Things I liked:

    Makes the look of the gun a whole lot better.

    Things I would have changed:

    I would have liked it to be made out of metal, something like aluminum maybe. I would also like a tube running all the way through the muzzle so that your ammo wouldn't get stuck inside the muzzle, especially BB's.

    What others should know:

    This is only for looks, If you want your gun to shoot better, invest your money into pellets.

    Things I liked:

    look, fit on barrel.

    Things I would have changed:

    Make it out of metal and widen the exit hole or make it a full barrel extension.

    What others should know:

    Made out of plastic and bb's sometimes hit the area around the exit hole and get stuck in the compensator. IMO the best souloutin is to drill it out, insert a K&S 7/8 brass tube and make it into a barrel extension

    Things I liked:

    This is the second one I have purchased in the last year. Both work great on my QB79s. A little electrical tape over the holes and you have a very effective moderator. They work on most all airguns with a 15mm barrel. Excellent.

    Things I would have changed:

    Nothing.

    Things I liked:

    Not much...

    Things I would have changed:

    It is too large in diameter, in person it looks something like a black wiffle ball. Expensive, too.

    What others should know:

    Does not affect sound very much.

    Things I liked:

    When combined with an outer covering of shrink tubing, it makes the Hammerli 850 unbelievably quiet. If quiet is important to you, then I highly recommend this.

    Things I would have changed:

    Bulky - makes the gun not fit into most gun cases. Overpriced for what it is.

    Things I liked:

    Nicely built, fits great on a 15mm barrel. Looks great on the the S200AA.

    Things I would have changed:

    Nothing.

    What others should know:

    I use it on a S200AA seems to change the sound when rifle is fired. I have tried it at the target range to check for accuracy changes, but with a windy day I had to dope for the wind, next time I will try in doors to see if there is a change when on.
