The quietest airgun silencer BRK has ever built – that’s our new MF 1/2″ UNF Moderated Frequency ‘MF’ Airgun Silencer! Available in Short (MF121) or Long (MF170) format. Each version is 40mm (1 9/16″) in diameter for maximum sound suppression. Plus, they are deliberately made caliber-specific for either .177 / 4.5mm and .22 / 5.5mm airguns. Our tests have shown that it will eclipse the performance of many of the more expensive custom brands! 1/2″ UNF Thread.

Both the MF121 and MF170 models are female threaded to fit barrels or adapters with a male 1/2″ UNF thread. This is the industry standard thread size for muzzle attachments. Therefore the BRK MF Air Gun Silencer will fit many makes and models of airgun, not just BRK-Brocock PCPs. They are machined using CNC manufacturing processes to ensure perfect bore alignment and ensure there is no loss of accuracy when fitted to the gun. Ideally suited for use with PCP (precharged pneumatic) airguns, they will also work well when fitted to spring-powered or CO2 airguns (with the correct muzzle thread or adapter). Lightweight and Practical

The BRK MF Air Gun Silencer will not upset the balance of your rifle. The MF121 Short model weighs just 151g / 5.32oz. The MF170 Long model weighs just 195g / 6.87oz. Both are finished in an anti-reflective matt black, so besides looking cool, they are more practical for field shooters wanting to stay hidden from quarry eyes.
