Choosing A Moderator

Airguns on the whole are fairly quiet when compared to shotguns and centerfire rifles.

But any lessening of the ‘crack’ that comes from your barrel will ultimately help you whilst out hunting. For target work or back garden plinking it’s not necessary but if you want to improve your hunting success, a moderator will help.

There are plenty of moderators to choose from. Some are just a chamber where the air behind the pellet is allowed to expand before exiting the muzzle, thus reducing the crack. More effective ones use a series of baffles, which can be purpose-shaped metal, and plastic.

Whatever type and size of silencer you use make sure its a perfect fit over the muzzle and is in perfect alignment with the bore of the barrel. If the muzzle of your airgun is not already threaded, a screw on silencer is best fitted by a gunsmith, but simpler sleeve-fit designs can just slide on to the barrel and be fixed in place by tightening a grub screw. Its always best to fit a silencer before you go to the trouble of zeroing your rifle because the moderator can have a very slight effect on velocity and also trajectory of your pellet, which can push your zero out.

Silencers are also called moderators. This is because the cylindrical device that many airgunners fit to their rifle barrels moderates the sound, rather than totally silencing it. Its true to say that some moderators do a better job than others.

For example, pre charged airguns can be more effectively moderated than spring- powered airguns. That’s because most of the power developed by the action on a PCP is a small tink of the valve opening and closing. The noisy part comes when the compressed air leaves the barrel, but its relatively easy to damp this down.

A spring gun has all the commotion of the spring expanding and crashing into the end wall of the compression chamber. You can lessen this noise if you take your springer to a skilled gunsmith who will polish and tweak the internals to make them smoother; or buy a springer with synthetic bearings like the Air Arms Pro-Sport.

    Hi, I’m just about to purchase an Air Arms S200 Target rifle & was wondering if it was possible to fit a silencer to it? I was hoping to be able to use it both as a Target rifle with the dioptre sights fitted & then be able to change over to a scope & silencer for field work.
    Is this possible?

      Yes, you can fit a moderator to the S200 target but as I am sure you are aware you will not be able to fit an open sight to this.

      No, the TX585 is not calibre specific and will work on both calibres

    Hi I have recently bought a AA TDR and I am very pleased with it. Does it come with a q tec silencer? Would it be even quieter if I fitted one?

    Mant thx

      There is a Q-Tech moderator available for the TDR and we believe it to reduce muzzle sound even further.

      Hi Tony, There are two moderators available in the UK. Your local Ar Arms stockist will be able to supply either the standard moderator, or the Qtek moderator.

    I’m looking for a moderator for my Air Arms S410-SL XTRA FAC. Just plinking in the back yard and would like to make it quieter. Thanks !

      If the barrel is threaded then you should be able to purchase a moderator through your local RFD. The part code is TX585.

    Will the Qtech fit my Tx200hc?

    • Team Air Arms

      November 21, 2016 at 11:51 am

      Yes, it is calibre specific, and you would need to order either part code S710-M-UNF-.22 or S710-M-UNF-177.

    Please advise suitable moderator to fit the pro sport that’s not had the barrel screwcut.

      Hi Robert, Air Arms do not manufacture a moderator suitable for the Pro Sport rifle.
