Maintenance back to top


Our silencers do not need much maintenance under normal conditions and will last for a long time with the recommended maintenance.

Dry the silencer as soon as possible after use.


After shooting, a silencer will be humid on the inside and it can take some days for it to dry if it is not opened. During this drying time the internal components can corrode. This is why we have designed our suppressors to be opened easily. This also allows the suppressors to be oiled on the inside before shooting and thereby eliminate the so called “first round pop”. 


Please note that putting too much oil inside will increase the amount of smoke (vapour) that comes out in the first shot. A dry, oiled suppressor can be stored mounted on the firearm.


Optimally maintenance should be done after each shooting session. Unscrew the front. For the featherweight models you should also take out the inner tube. This will allow the internal components to dry immediately. If for some reason it is not possible to open the suppressor, spray some gun oil inside and let it dry.


Do not put the silencer into the dishwasher or use detergents for cleaning. This may damage the silencer. Oil works best for dissolving powder residue.

The featherweight line and the Freyr 280 Titanium have a slightly different construction, but even so they have the same maintenance procedure.


uts series

Our UTS line is not designed to be opened. Apart from not being able to open, the UTS line have the same maintenance procedure as the featherweight line and the Freyr 280 Titanium. Dry the silencer as soon as possible after use. Store in a dry place. 



Procedure featherweight line and 280 titanium

1.Open the suppressor, spray plain gun oil on to the inside parts and into the rear chamber. 


2. Oil lightly and wipe the powder residues. When it comes to the Featherweight line you should pay special attention to the contact area between the inner tube and the baffle stack. If this is not done the inner tube will eventually stick to the baffle stack. It is recommended to put grease on the sides of the bafflestack before putting the inner tube on this will make later disassembly easier.

3. Grease the threads before assembly. It is not necessary to clean the silencer completely.
4. Use silicon based o-ring grease for the o-ring at the front. “Molycote 111 for example”

With use of the silencer there will be a buildup of powder residue on its inside. It should though be noted that if water enters a heavily fouled silencer the powder residues will absorb water and form crystals. This should be kept in mind when hunting in rainy weather. A more thorough cleaning is then recommended beforehand. The silencer should be disassembled for cleaning and inspection. Follow the guide above. If the suppressor is regularly maintained and threads lubricated this can be done without tools. It can then be cleaned by spraying the baffle stack and the inside of the outer casing with gun oil and wipe the dissolved powder residue off.  Then oil the internal parts lightly and lubricate the threads before assembling. Verify that the O-ring is intact.

 A qualified gunsmith shall always fit the suppressor to the firearm. The suppressor must be suited for the caliber of the firearm. Caliber and thread are indicated at the front of the suppressor. The center hole of the silencer must be concentric with the bore of the firearm. This must be verified before using the firearm.

The rifle has to be zeroed after mounting the silencer. It is not recommended to shoot series longer than 20 shots without allowing the silencer to cool down. The silencers are intended for civilian use only. Always ensure that the silencer is in good condition and without damage and properly mounted before use. When using insulating covers, the cover should be removed between series to let the silencer cool down. Improper use may result in injury and damage to equipment. Always use protective eyewear and ear-protection when operating a gun, even with a silencer on. The silencer should be removed from the firearm after use and stored in a dry place in such a way that air can flow through the suppressor. After shooting at the range it is recommended to have the rifle standing with an open breech to let air pass through and dry the silencer.
