Gunworks currently leads the centrefire rifle sound suppressor market, introducing the overbarrel suppressor concept in the early 1990’s.
Suppressors are made from a combination of stainless steel internals and aluminium body to reduce weight. Life expectancy of the unit is in excess of 16000 rounds from the ones we have checked when changing barrels.
Fitting time is 3-4 working days. We recommend that users consider shortening their barrels slightly when the suppressor is fitted to reduce the overall length of the equipment, for example, a .223 with a factory standard 23 inch barrel would probably be bought back to 20 inches without any noticeable decrease in performance.
These suppressors are a 2 point mount and are impossible to knock out of alignment (as may happen with muzzle forward cans). All suppressors incorporate a barrel isolator tube which prevents carbon and gas sticking to the outside of the barrel under the suppressor.
Sound signature of a high velocity round for any caliber, ie .222 Rem to 7mm mag, is similar to a stock whip cracking (or a 22 magnum thereabouts), that is the noise of the projectile breaking the speed of sound. When used on game, the animal only notices the “stock whip” like crack originating above them. The position of the firer is undeterminable. This often leaves the animals milling and unsure of where to run, particularly at night under a spotlight.
- Trapping: The suppressor's baffles create a series of chambers that trap the expanding gases.
- Cooling: The trapped gases are allowed to slowly cool down.
- Reduced speed: The gases exit the suppressor at a much slower speed than they would without the suppressor.
- Reduced noise: The reduced speed and cooling of the gases produces less noise.

Reasons for suppressor ownership:
- Reduces hearing damage
- Reduces fright to other game animals
- Reduces damage to the hearing of hunting dogs
- Reduces concern among other outdoor users
- No reduction in accuracy or hitting power.
The main difference between the 35mm and the 41mm suppressor (other than diameter) is the length forward of the muzzle. The 35mm is 5" foward and the 41mm can be 4" forward.

35mm dia 13.5" Stacker (Modular) duralium suppressor (comes with 2 stacker baffles) - Reduces recoil by half and removes 2/3rds noise
Suitable for 22 Hornet, 204, 222, 223, 22-250, 243, 260, 270, 280, 308, 7.62x39, 30-06 etc (not magnums or PRC calibers)
The Stacker Suppressor is sold as a 13.5" (335mm) long unit. By removing the baffles you can reduce the total length to 11.5" (285mm), weight will reduce to 301grams however best performance of noise reduction will also reduce. We have found the "sweetspot" for overall performance is using 2 or 3 stacker baffles.
Weight — 301grams - 353grams (alu internal muzzlebrake 5-6,000 rnds) and the weight depends on how many stacker baffles you use, bearing in mind you get your noise reduction from your forwardness so the less forward you are the less noise reduction you acheive.

41mm dia 9" Hybrid "Cleanable" Spartan Duralium Suppressor - Reduces recoil by half and removes 2/3rds noise
We have two multi calibre suppressors available in the hybrid model and this is possible because the hybrid baffle system has tight tolerances allowing the small ranges of calibre. The hybrid baffle system also lowers the risk of stray bullets and bullet strike.
The first is suitable for 22 Hornet through to 243 including, 222, 223, 22-250, 243.
The second suppressor is suitable for 6.5 through to 30-06 including 6.5 prc 270, 7mm-08, 284, 280, 308, 7.62x39 etc (not including 300 PRC or belted magnums).

These are our first "cleanable" suppressors – the “Hybrid” design was a pull apart suppressor that Robbie had begun creating prior to his death in 2018. In 2022, our gunsmiths took Robbie’s vision and made it a reality.
The 41mm 9" suppressor is most suited for those who like to clean their suppressor. Its great for those who need a light suppressor and prefer to be 4" forward of the muzzle rather than 5" forward of the muzzle.
These two videos show the suppressor in action on a 223
This next video is of Sean cleaning Gunworks new Hybrid "cleanable" suppressor after 500 rounds (don't use brake clean like Sean though!!)
50mm DIA MAXIMUS SUPPRESSOR - Reduces recoil by half and removes 2/3rds noise
Dimensions: 50mm outside dia. The muzzle forward portion of the suppressor can be anywhere from 75mm to 125mm. The longer it is the better the suppression but some users want to keep the length down.
All applications when a big suppressor is desired, ideal for bull barrel rifles, heavys, subsonic, wildcats.
