RAT Works Airgun Shroud Backflow Air Stripper - Standard

Most airgun shrouds have a shroud support fitted to the end of the barrel, this is often simply a bush used to support the shroud body and does not help reduce the muzzle report of the rifle. 

This ½” UNF threaded bush attaches to the threads on your barrel and strips the air off and ‘backflows’ the blast of air upon firing, using the internal volume of the existing shroud over your barrel to improve the moderation of your muzzle report. The largest part of the air stripper has a 28mm OD. 

This item is threaded 1/2” UNF to fit most airgun barrels on air rifle brands such as BSA, Gamo, Hatsan & FX. Please check before ordering that your barrel is threaded to a ½” UNF specification such as AGT barrels. These are also calibre specific to help maximise efficiency and designed to be fitted inside an existing shroud of up to 28mm Internal Diameter, down to 22mm.  


This item can be used to create your own shroud/moderator or can be used in an existing shroud/ moderator.


Please note, not all bores are true to the threads, this is especially apparent on hammer forged barrels such as BSA and HW barrels but can also be found on the button drawn barrels too. If the bore of the barrel is considerably ‘out’ compared to your threads, choose the next calibre up to avoid the chance of damage when firing.

In general, a bush for a 4.5mm bore will be supplied at 5.5mm in the stripper to give some tolerance. When fitting the bush for the first time we recommend removing the barrel for a visual inspection down the bore (once the stripper is fitted) to check that no clipping will take place in the pellet path. Fire a lead pellet to check for any damage to the stripper before reassembly of your shroud components.
