Silencer NZ

Gunworks NZ designed the first overbarrel silencer and revolutionised the noise reduction technology. The details of our range of silencers are given below:

 

 Key points for Gunworks Suppressors:

  • Sound signature of a high velocity round for any calibre, i.e. .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. Our silencer quality ensures that 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.
  • Fitting time is 7 – 10 working days. We recommend that users of our silencers 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.

1. Lightweight suppressors

Light weight over barrel suppressor:

silencer nz

The light weight is 5″ forward of the muzzle and 7″ back.

Weight: Stainless steel internal muzzle brake approx 380-400grams 20,000 rounds Aluminium internal muzzle brake approx 330-350grams 5,000-6,000 rounds

All Lightweight custom made suppressors are made to suit one calibre and one rifle only.   The lightweight suppressor can be made for calibreswith less than 30gns powder capacity such as .223, 7.62 Russian, 30 Whisper etc. One suppressor is not suitable to be put on any calibre, it is made caliber specific.  Please note, custom made lightweight

suppressors cannot interchange between all calibres and rifles, they are made for one rifle and one caliber only.  Reduces noise by 2/3rds and removes half recoil. 

 Reduces noise by 2/3rds and removes half recoil.

PRICE: $460 incl GST          

Price incl: Custom built rifle sound suppressor, threading, custom built thread protector cap, suppressor bag

FREIGHT:

$15 Return freight of rifle

 

2. Standard Weight Suppressor

Standard weight Overbarrel Suppressors:

Standard weight extends to 5″ forward of the muzzle and 8″ back.

Weight: Stainless steel internal muzzle brake approx 480-500grams 20,000 rounds Aluminium internal muzzle brake approx 430-450grams 5-6,000 rounds

 

All Standard custom made suppressors are made to suit one calibre and one rifle only.   The standard suppressor can be made for calibres 22-250, .243, 7mm-08, 270, 308 or 30-06 etc. One suppressor is not suitable to be put on any calibre, it is made caliber specific.  Please note, custom made standard suppressors cannot interchange between all calibres and rifles, they are made for one rifle and one caliber only.  Reduces noise by 2/3rds and removes half recoil. 

The key difference (other than price) between a standard suppressor (suitable for calibres 22-250, .243, .308, .270, 30-06, 7mm-08 etc) and a duralium suppressor (suitable for calibres 22-250, .243, .308, .270, 30-06, 7mm-08 etc) is weight, so, if weight is not an issue for you we suggest you consider the standard suppressor $460 incl GST weighs 480-500 grams. If weight is an issue for you, we suggest you consider the duralium suppressor.

PRICE: $460 incl GST

Price incl: Custom built rifle sound suppressor, threading, custom built thread protector cap, suppressor bag

$15 Return freight of rifle

 

3. Duralium Overbarrel Suppressors

Duralium Lightweight Alpine rifle sound suppressor:

Duralium suppressor extends to 5″ forward of the muzzle and 8″ back.

Weight: Stainless steel internal muzzle brake approx 370-390grams 20,000 rounds Aluminium internal muzzle brake approx 340-360grams 5-6,000 rounds

All Duralium custom made suppressors are made to suit one calibre and one rifle only.   The duralium suppressor can be made for calibres 22-250, .243, 7mm-08, 270, 308 or 30-06 etc. One suppressor is not suitable to be put on any calibre, it is made caliber specific.  Please note, custom made duralium suppressors cannot interchange between all calibres and rifles, they are made for one rifle and one caliber only.  Reduces noise by 2/3rds and removes half recoil. 

 

Reduces noise by 2/3rds and removes half recoil. It is not available on magnums or 270′s with a barrel length under 19″

The key difference (other than price) between a standard suppressor (suitable for calibres 22-250, .243, .308, .270, 30-06, 7mm-08 etc) and a duralium suppressor (suitable for calibres 22-250, .243, .308, .270, 30-06, 7mm-08 etc) is weight, so, if weight is not an issue for you we suggest you consider the standard suppressor $400 + GST weighs 480-500 grams. If weight is an issue for you, we suggest you consider the duralium suppressor.

After years of extensive testing we are offering our Light Alpine duralium sound suppressor for cartridges up to 65gn powder capacity, ie 243, 308, 270, 30-06 etc. Weight is 370-390gms or 13 oz which is exceptionally light for an overbarrel suppressor capable of containing that powder charge.

We are air freighting wpn grade Duralium from California for this project, as we can’t source what we require locally.

We have always wanted to create a true light weight suppressor for South Island alpine conditions, where weight really is a serious consideration, but have not been happy with the usual grades of aluminuim for this task, early experiments showed the problem of stretching and bulging over would occur after a number of rounds.

Duralium gives the tube a similar strength to mild steel but without the weight, titanium is also an option, but too heavy for us, being half way between steel and aluminium.

Additional tweaking of the internals are also required to achieve our weight limit and to provide the legendary GUNWORKS sound reduction.

PRICE: $517.50 incl GST

Price incl: Custom built rifle sound suppressor, threading, custom built thread protector cap, suppressor bag

4. Maximus Overbarrel Suppressor

The 50mm dia Maximus suppressor is suitable for the following: All applications when a big suppressor is desired, ideal for bull barrel rifles, heavy caliber, subsonic, wildcats, AR’s with large diametre floater tubes.

 

Remington 788 .45 ACP is fitted with a Maximus suppressor 10″ forward which covers the whole barrel. The weight of the suppressor is 1197 grams.

 

North eastern arms AR15 .223 is fitted with a 6.5″ Maximus suppressor which sits 4″ forward and 2.5″ back which makes it 1mm off the hand guard. The weight of the suppressor is 433 grams.

 

AR15 .223 is fitted with a 10″ Maximus suppressor and sits 4″ forward and 6″ back.

 

 

Tikka T3 303win is fitted with a Maximus suppressor which sits 5” forward and 5” back. The barrel length was shortened 14”.

   

Remington 700 .223 has been fitted with a 18” Maximus suppressor body which sits 4” forward and 14” back to the stock. The barrel is not shortened.

Rock River Arms Lar-9, 9mm is fitted with a 10” Maximus suppressor, sits 1mm of hand guard.

Howa .308 is fitted with a 10″ Maximus suppressor the barrel is heavy fluted with square flutes & the length of the barrel is 22”.

Rossi Wizard .223 fitted with a 10” Maximus suppressor, 4” forward & 6” back.

Rock River Arms .308 fitted with a Maximus Suppressor which sits 3″ forward and 4″ back from the front sight.

50mm outside diameter 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. The maximus lets us hold the large volume forward of the muzzle and is remarkably effective, even in short form. The rear of the suppressor from the muzzle towards the stock can be the customer’s choice, we recommend probably no more than 8” back, due to the weight increasing the more the suppressor is increased in size. Again the design is such that the customer can configure it however they want and we will build it to that specification.

PRICE: $460 incl GST

Price incl: Custom built rifle sound suppressor, threading, custom built thread protector cap, suppressor bag

Available with our stainless steel internal muzzlebrake, or available with our high tensile aluminium muzzlebrake.

22-250 – .30cal

 

Available with our stainless steel internal muzzlebrake – 20,000 approx rounds suppressor life. Also available with our high tensile aluminum muzzlebrake – 5,000-6,000 approx rounds suppressor life.

The main objective behind universal suppressors is so that you can use the one suppressor on more than one rifle/caliber or to fit yourself. Please note not all calibres can be interchanged as they are too far apart and the smaller caliber can be less effective with noise reduction, because of this we don’t recommend putting a 30cal on a 22-250 or .223 etc but on a 7mm or 270 is fine. To get the most sound reduction out of your universal suppressor we have put together a guide so you can see what calibres work best together for this type of suppressor.
