Designed and made right here in Christchurch New Zealand, Gun City has been making silencers since the mid 1980’s. With over 25 years up our sleeve, we feel we have the best range of silencers available in the world! Using the latest machines and the strongest lightest materials our silencers will ensure the following results.


  • Lightweight design - an alloy body machined out of one solid alloy bar (the dense alloy material is also better for sound reduction than stainless steel).
  • Strong one-piece mono baffle system - with all four chambers machined from one piece we ensure maximum strength to handle all rimfire loads.
  • Overbarrel isolating tube - our clever muzzle brakes force most of the gases back into an isolated tube over your barrel. Having this part of the silencer come back over your barrel means it is a lot better balanced than a traditional muzzle forward silencer which does not have as much volume as the over-barrel system.
  • Maximum gas capture, along with our large chambers we have also shaped tapered slots into each chamber to ensure maximum gas disruption resulting in a quieter silencer
  • Maximum noise reduction for its size (we guarantee no silencer the same size or smaller to be quieter).


  • Weight: 360g
  • Length: 310mm
  • Diameter Outside: 40mm
  • Length (Over Barrel): 150mm
  • Diameter (Barrel It Will Fit): 19mm
  • Calibre: 22, 30 and 9mm

This silencer will fit any centrefire rifle with 17cm of exposed barrel and a diameter smaller than 19mm. Helps protect your ears from permanent hearing loss. This silencer's super strong tooling grade alloy construction is designed to withstand bursts of full auto fire, making it virtually indestructible on a hunting rifle and keeping the weight down to just 370 grams.

As a lot of customers want to fit one silencer to more than one calibre we have come up with a design that will fit more than one rifle. This is achieved by a simple barrel bush in the back of the suppressor, comes with one bush and extras are available at $20 extra.

  • 22Cal- (8.5mm Hole) will do any .22/5.5mm calibres like 222, 223, 223WSSM, 220, 22-250 etc.
  • 30Cal- (10mm Hole) will do any non Magnum calibres 6mm through to 8mm. Like 243, 6.5x55, 270, 7mm-08, 308, 8mm.
  • 9MM- (9mm Hole)

We can fit these to your rifle for $100 or point you to a gunsmith in your area that can.
