What are the difference between T42 and T50 models compared to the T42 II and T50 II?


1. All TRITON II have a new rounded front design.

2. All TRITON II have an internal upgrade to decrease the effect called "First Round Pop".

3. The new T42S II have is just adding 128mm. but has the same noise reduction as the origin.

4. The T56S II is also reffered to gen II due to the same change as the other TRITON silencers.



How much do the TRITON silencers add to my barrel length?


Maintenance, how do I clean my TRITON?


The TRITON silencers are all designed to be as maintenance-free as possible. There are, however, a few things that are important to remember:

Burning powder leaves residues, among those water that reacts and creates ammonium. Therefore – always remove the silencer after being in the field and keep it warm and dry so any humidity dries out. Also unscrew the front part just to make sure the silencer threads are greased with thread paste so it does not get stuck. After this - ensure that the threads and the shoulder surface behind the threads on the rifle are clean and when this is done put on some thread paste.

Never use thread paste that contains metal. (Copper paste etc)

Cleaning as outlined above is all what is required.


How do I know which thread to cut on my barrel?


Measure the diameter of the barrel where the thread is to be cut. Remember that the diameter normally increases backwards – good to know if you are planning on cutting the barrel before making the thread.

A rule of thumb is that there shall be an edge (shoulder) of 1.0mm at the end of the thread. This acts as a stop and it is also this edge that aligns the silencer with the barrel. Consult your gunsmith – he will know which thread to recommend on your rifle!

Some examples:


A barrel with the diameter of 16mm is normally threaded M14x1 (by far the most common thread)

A barrel with the diameter of 17mm is normally threaded M15x1 (for example Blaser rifles)

A sporter/varmint barrel with a diameter of approx. 22mm normally is threaded with M18x1 but if you want to use the same silencer on other rifles M15x1 is a good alternative.


What kind of threads exists?


Metric threads with the rise of 1 mm/round are the most common.

Some time ago a 1.5mm rise was commonly used but the thread with the 1.0mm rise increase the contact surface as well as does not cut so deep as the 1.5mm.


Imperial threads

UNF (fine) correspond to the metric 1.5mm rise (1.27mm)

UNEF (Extra Fine) correspond to the metric 1mm rise (0.907mm)

Rifles with thin barrels can use 13x1 or ½x28 UNEF


The length of the thread is normally 15mm and shall be equipped with a groove closest to the edge (shoulder).

The thread shall also be beveled at the front so that the entry of the thread is protected.


How much can I shorten the barrel?


Cartridges like .308Win, 8x57, 9.3x57 (also 9.3x62), 45-70, 30.06 can be shortened more or less. Of course there are other calibres that “accept” a shorter barrel without losing too much speed, but a basic rule is to never shorten the barrel on a Magnum calibre or on a rifle where you demand the highest possible speed!

Different countries have different rules in how short a rifle barrel can be to still be legal. It is always smart if cutting a barrel to not cut it more than to a level where you still have “one more go” before reaching the minimum length – a good insurance if the thread has to be re-cut if the first is damaged.


How is the speed of the bullet affected by the silencer?


The speed of the bullet is normally increased by 5-10m/s depending on silencer, calibre, barrel length and the load.


Can I use I TRITON on a semi-automatic rifle?


Yes, but it requires that your rifle can adjust the re-loading gas pressure.

All semi-autos can be “re-built” to work with silencers but it is important to remember that the warranty of the rifle can be void if the rifle has been manipulated or that components have been used in the weapon which are not approved by the manufacturer!


Will the point of impact be changed with a silencer fitted to the rifle?


Yes, it is unusual to get the same point of impact with, and without a silencer. In a “perfect world” with a silencer the point of impact would be slightly lower but also with an improved grouping i.e. with increased accuracy. The explanation is that the silencer reduce the barrel-rise (recoil) and also the barrel vibrations thanks to the extra weight placed on the barrel. Reduced barrel-rise=lower point of impact and smaller vibration of the barrel =better grouping.

The effect with silencer and the improved grouping is most obvious on light-weight rifles and/or on rifles with thin barrels. Other that affects the point of impact is the centering of the barrel thread and tolerances in the manufacturing of the silencer. All deviations will influence the point of impact and therefore it is not unusual that the point of impact sometimes is moved slightly sideways.

The most common experience however is that shooting with a silencer improves the grouping and creates a more relaxed shooting!


Can a TRITON be used on stainless steel barrels?


Yes, the thread in the TRITON is made of stainless steel and can be used on stainless steel barrels, but there are some important notes to pay attention to!

If you want to attach the TRITON to a stainless steel barrel and you sense a resistance when screwing it – STOP immediately!

Never force two stainless steel threads together as the metal will “weld them together” and cannot after this be separated.

If you sense this resistance – ask your gunsmith to “clean” the thread that does not fulfill the 6h/6H standard.


How is noise reduction measured?


The normal standard used when measuring impulse noise is called MIL-STD-1474D.

The measurement is done with the microphone placed 160cm above ground and at a distance of 1.0m at a 90 degree angle from the barrel muzzle. A .308Win without a silencer is normally measured at 168dB (Peak SPL). A silencer is only reducing the noise from the exploding gases by reducing the pressure sequentially through expansion in a number of chambers.

A bullet in supersonic speed creates a supersonic “bang” at approx. 140dB on 1 meter distance throughout the whole trajectory. This supersonic “bang” cannot be reduced!


The working environmental law limits stated by the EU has a peak noise level of impulse noise of 137dB which is not supposed to create permanent hearing damage. Measurement shall be done at the shooters left ear for a right hand shooter.

Example of how you can re-calculate to MIL-STD-1474D when measuring at the shooters left ear:

The noise level is approx. 8dB lower at the shooters ear when firing thanks to the shooter being behind the rifle. For a .308Win this means 160dB non-reduced at ear (168dB – 8dB) and if we reduce the noise on that .308Win with a TRITON 50II we will measure 132dB at the ear. This gives us a noise reduction of approx. 28dB (168dB – 8dB – 132dB).
