Not every air rifle or air pistol comes from the factory with a silencer thread – and even shooters who already own a silencer often want to use it on more than one gun. That's exactly what these adapters, extenders and spare parts are for. One thing to watch when buying: adapters are usually model- or thread-specific, so check your weapon model or existing thread carefully before ordering.

Model-Specific Silencer Adapters

For guns without their own silencer thread, we stock purpose-fit adapters with a 1/2"x20 UNF outer thread: for the Anschütz 9015, the Air Arms S300/S400/S410 with a 10mm muzzle and the Air Arms S510 TR Tactical (BEST Fittings), for the German version of the AEA HPMax MK1 and MK2 (DonnyFL, M18x1 thread), for the Huben GK1/GK1 Mini Pro and the Huben K1 A9 (not for 1st-gen K1), for the Evanix MP30 and Evanix Viper Cal. 30, for the Weihrauch HW 44, and a universal 1/2" UNF adapter for the Steyr Challenge Hunting, Challenge HFT Hunting, ProX and Hunting 5 Automatic.

Slide-On Adapters for Smooth Barrels

If your air rifle has no silencer thread at all, the DonnyFL slide-on adapters with a 1/2"x20 UNF outlet help out: available in 14mm and 16mm barrel diameter, for .177/.25 caliber, including an M4 set screw for fixing.

DonnyFL QD Conversion and Barrel Adapters

To make a DonnyFL silencer instantly detachable, there are QD connection adapters for the Sumo/Tatsu/Shogun, Ronin/Emperor/Fatboy and KOI/Tanto model lines, screwed onto the rear of the silencer. The matching counterpart for your barrel are the QD barrel adapters in M1/2x20, M14x1.25, M18x1 and M20x1, which are fitted to the barrel once and then allow a quick twist-lock swap afterward.

Extenders for More Sound Suppression

If your 10.5-inch DonnyFL Emperor v3 or your Ronin still isn't quiet enough, the 6.26-inch extenders (available in 1/2"x20 and M18x1) increase the internal air volume for extra sound reduction. For the Fatboy 2.0 there's a matching extension tube. Note: the extenders aren't compatible with the DonnyFL QD barrel adapter, and the front cap has to be removed before fitting.

EDgun Leshiy 2 – DonnyFL Shrouds

Built specifically for the EDgun Leshiy 2, we offer DonnyFL shrouds in 250mm and 350mm, both hollow for maximum air expansion, made from black-anodized 6061-T6 aluminum with a 1/2"x20 outer thread. Fully folding the stock also requires the extended pin from Edgun West.

DonnyFL Yokozuna Replacement Chambers

For the DonnyFL Yokozuna silencer we offer individual replacement or extension chambers in the .22 (5.5mm), .25 (6.35mm), .30 (7.62mm) and .357 (9mm) caliber versions – letting you adjust the silencer's length individually or swap out a damaged segment. The manufacturer recommends extending the standard build by no more than two additional chambers.

Frequently Asked Questions About Silencer Accessories and Adapters

My air rifle has no silencer thread – what now?

If your barrel is smooth with no internal thread, a slide-on adapter such as the DonnyFL models in 14mm or 16mm barrel diameter helps – it slides over the barrel, gets fixed with a set screw, and provides a 1/2"x20 UNF thread for your silencer.

What's the benefit of a QD adapter?

With a QD barrel adapter (fitted to the barrel once) and the matching QD connection on the silencer, you can quickly screw the silencer on and off going forward without re-threading each time – handy if you take it off regularly or use it across multiple guns.

Can I increase my silencer's sound suppression after the fact?

With some DonnyFL models like the Emperor v3, Ronin or Fatboy 2.0 that's possible: a matching extender increases the internal air volume, further reducing the report.

Does every adapter fit every gun?

No, most adapters in this category are built for a specific weapon model or thread size – always check exactly which model or thread size the adapter fits before ordering.
