Whisper 180 Silencer

Whisper 180 Silencer

Plus, looks alone can do it for many of us, and there’s no doubt that a flashy ‘moddy’ up front can transform many a gun’s profile; but of course quietening the shot blast remains the main advantage to be gained.

Okay, where a spring powered rifle is concerned, the difference in muzzle report is rarely dramatic, given the inherent noise from the mechanical action; and this can be difficult to overcome. Yet fit that same moderator to a pneumatic, be that single stroke, or PCP, and you’ll be amazed. Rapidly expanding air from the muzzle can make a real crack, and it’s this that can be tamed significantly by the addition of a silencer.

Long Version

On test here is the long version Whisper 180 from Deben Group, and it comes well-appointed. The main aluminium anodised body is 8-inches long and comes fitted with a full-length grey rubber shroud, which not only looks sleek, but also offers a non-reflective surface; super practical where hunting is concerned.

Supplied packed with four different adaptors, this model is ready to fit a variety of barrel dimensions. 1⁄2-inch UNF male, 1⁄2-inch UNF female, one slide-on 11mm (Air Arms), and a slide-on 16mm (bull barrel) all come as part of the pack. I decided the silencer was to be tested on my main competition rifle, an Air Arms S400, so the first job was to unscrew the ready fitted adapter from the rear of the silencer body, and screw in the dedicated slide-on 11mm adapter (specified as Air Arms incidentally). This then simply slides onto the end of the barrel and needs a gentle nip up with an Allen key. Weight and dimensions are very similar to the factory Air Arms model that I normally use, but the slide-on adapter supplied, whilst a good fit, just wasn’t quite such an ultra-snug fit as the factory spec.

story continues below...

That said, once tightened in place, all felt reassuring, and an all-important zero check at 30 yards revealed that this particular gun’s blistering accuracy was totally unaffected and still on song- proof of the pudding with the application of any moderator at the end of the day.

Report Card

As for muzzle report, I don’t possess a decibel meter to run a test as a technicality. What I can report, however, is that despite my own factory Air Arms model being highly effective as a sound suppresser, this Whisper 180 is just that bit better, detectable by ear! Expansion chambers are the name of the game, along with a series of strategically placed internal baffles and felt wads – all used to great effect. Add in a high-standard of manufacture, the versatility of those adapters, and great looks, and these silencers have to come highly recommended.

PRICE: £47.95 (6-inch model: £39.95)
