Silencer adaptor for Air Arms S510 with 21mm lead in thread

You will need to remove and measure the thread on your original Air Arms silencer and make sure it is approximately 21mm

Some rifles have a shorter thread and will not be compatible.

Terminating with a 1/2″ 20 UNF Male Thread, this adaptor allows the use of any silencer or bespoke muzzle brake with 1/2″ 20 UNF Female Thread (Standard UK Airgun Fitment).

Matt Black Anodised Aluminium.

Comes complete with a knurled thread protector end cap for when no silencer is installed.

Screw in fitting.
