Modify for Suppressed Sound
December 11, 2013
This thing is easy to install and will suppress sound if modified. I wrapped it in Scotch Professional Grade Super 33 vinyl electrical tape and then covered that with standard electrical tape to clean up the appearance. It will eliminate all sound except for the click of the trigger.
easy to install well built

Quiet City :) BAD TO THE BONE :)

Got it for my Hammerli 850 77 cal. Wrapped electrical tape around it finely back to front. Looks great sounds sound ....I mean..... hammer and hit are all you hear. Gun rated 3 but I would say 1 with this. Amazing Brake how sweet the no sound :):):) I don't know what it's made of and do not care. It does it's job and looks BAD TO THE BONE!!!!!
Makes gun sound invisible. Airgun Depot has great prices!!!

Mostly For Looks
May 6, 2013
Main reason for buying was mostly for the finishing looks for my rifle. It has given my RWS 850 that flash it needed. Like wearing a expensive suit and the Compensator being the high class tie.
I like the looks, the built quality seems to be good the packaging was very good the price was a little steep for what it is. I did not notice any difference in sound when shooting but that's fine with me as I shoot inside my 2 1/2 car garage with both doors down. I didn't want to put tape or any other item on the compensator that to me is not why I bought it for. I mostly wanted to finish off the looks and it has done that for me. So why ruin the looks by tapping it all up I understand that some will be shooting this outside for hunting and will need to do what ever to make there rifle a little less noisier. I'm shooting this on my RWS 850 for target shooting only.
Price seems a little high but then again people spend tons of money on car rims to get that special look. So spending what I did seems to be a good buy in my book.

Silent sniper

I love this compensator. all you have to do is cover the holes with electrical tape and you have a really quiet suppressor. I Owen a hamerlie 850 airmagnum. I use this gun for varmint control. My neighbors don't even notice!! I usually do my shooting at midnight. My YouTube Chanel 6854155 have a videos using this compensator.
Easy installation, and provides the Allen tool for the two screws.
Price, but I got it for $15 using my rewards points :) Best program from AGD.

Compensator for Beretta CX4 Storm, RWS 850, Umarex EBOS and Walther Dominator
July 8, 2012
Cool little item. I am using it on my Umarex EBOS. A little expensive for what it is, I made some mods to it so it works more efficiently. I had to drill out the exit hole to a larger size because the bb's were contacting the edge of the hole. I added some expanding foam to the ports on the muzzle side to quiet it down and covered the ports on the exit end with black duct tape. This make the EBOS a much more quiet gun. Plus it LOOKS really cool.
Good looks
A little pricey.

Compensator for my RWS 850
December 4, 2011
This is apparently the same piece that (sans holes) is marketed as a silencer overseas. It bolted onto my .22 RWS 850 air rifle(great plinking gun, btw).

Good product

If you slip a piece of tubing over the outside it makes a fantastic suppressor. Check laws in your area.

Very Good
October 26, 2008
This compensator is very good, works very well with the RWS/Hammerli 850. designed for heavy gauge barrels (0.60" inner diameter of the compensator), before buy verify the diameter of your barrel, just to be safe. Deflect CO2 gases excellent, very easy to install. Very Recommended!!

What is this primarily used for? Its just for looks thats way overpriced for a aluminum cylinder. Why not just use a tin can and put holes then theyd be twins.
By Staff on March 14, 2012

It is mostly for looks though it can dampen noise a small amount.

Will this work with the px4 storm?
By Staff on April 11, 2012

No it will not fit that gun.

By ralph from adams, TN on November 17, 2011
