Magnum Over Barrel Centrefire Silencer

The Greystone Guns Magnum model silencer is our most popular silencer giving great decibel reduction from the smallest 17 cal right up to 300 Win Mag and impressive recoil reduction as well.

  • Overall length 350mm
  • 150mm forward of muzzle / 200mm rearward of muzzle
  • 38mm outside diameter tube
  • Weight: Approx 500 grams

Greystone Guns Over Barrel Centrefire Silencer

The Hunter the Magnum and the Magnum XL model over barrel centrefire silencers are available to suit three different size projectile groups for centrefire rifles up to powder capacity of 300 Win Mag.

  • .17 to .224 projectiles
  • .243 to .260 projectiles
  • .270 to .308 projectiles

This means you can effectively use the same silencer for any calibre within the projectile size bracketing. You can also use projectiles smaller but they will not get quite the same decibel reduction as they would if they were in their designated bracketed area. The silencers have a removable Acetal Plastic rear bush which needs machining out to the barrel diameter.

Spare bushes are available for $30 so you can easily use the same silencer on different calibres within the projectile size grouping and with different diameter barrels, however the thread size/type must be the same on all barrels though.
