This pistol suppressor booster housing assembly is the same assembly utilized by the Resistance® 9 & 45, Revolution 9 & 45, & Optimus 9 suppressors. 

The booster housing itself is manufactured from solid, high temperature corrosion resistant 17-4 Stainless Steel, and then H900 heat treated to maximize service life and has a lustrous black nitride finish.  The outer thread pitch of the housing itself is 1.2875x24, an industry standard for 1.4" tube body suppressors. Our booster piston springs (replacements available separately), manufactured from 17-7 stainless steel wire, offer excellent resistance to corrosion, superior fatigue properties, and exceptional rigidity and durability. The booster housing piston retainer nut is constructed from 6061 T6 aluminum, with type 3 mil-spec hardcoat anodizing.  The thread pitch of the booster housing piston retainer nut is 1.125x28, this is the same booster housing piston retainer nut utilized by the Bushwhacker 46 booster housing assembly. 

This booster housing (available for purchase by itself) is a great option for customers who would like to keep a 3 lug interface assembled in a booster housing and would like to simply swap booster housings when changing between fixed barrel and tilt barrel applications. This is also a great option for form 1 builders who are in need of a booster assembly to make their firearm reliably cycle when suppressed.

    Booster Housing Repalcement

    Published by Tom Demaree on 2nd May 2024

    Ah, a factory original replacement! It replaced the housing I damaged when I didn't make sure the piston was all the way down in the housing before I tightened the retainer nut, and then tried to attach the suppressor to the adapter--will I never learn how to reassemble the housing after cleaning it? Arrgh!

    Replacement Booster Assembly for Resistance 45

    Published by Bill on 19th Feb 2022

    Bought a Resistance 45 can and a Cam-Lok Piston from Silencer Shop and just rcvd the tax stamp and can. When installing the piston into the booster assembly, the fit was so tight I had to force the piston in. Contacted Griffin and spoke to Richard. He asked that I send a short video. I emailed the video and Richard contacted me within minutes to tell me they were sending me a new booster assembly and cam-lok piston. Shipped all the way from WI to PA and rcvd replacement in 2 days! I’m a retired Marine Sergeant Major, and don’t throw around gratuitous accolades; Griffin customer service is superb and the best I think I ever had in my life!! Semper Fi Griffin team….you have a loyal customer for life!

    Handy option

    Published by Joe on 7th Oct 2021

    Had inquired about these months ago and were not an option so glad to see them now available. Ordered the housing to swap back and forth between 3 lug and booster piston more easily and works as expected.
