This booster housing assembly is the same assembly utilized by the Bushwhacker® suppressors. This can also be used with the EXPLORR® utility mount series. 

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 1.375x24, a common industry standard for many 1.5" tube body suppressors. This thread pitch is also known as HUB, universal, and others. 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 Pistol suppressor 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.

    Great product - Hub mount

    Published by James Moses on 27th Mar 2024

    Great product that I used to mount EZ-LOK QD to my Deadair Primal. Worked perfectly. So happy to switch between my Glock 17 and my FN 545. So easy to switch between calibers. I also had to get the Griffin Armaments piston but it was well worth it.

    I initially ordered the wrong size but Griffin was excellent in helping me correct the issue. This works flawlessly with my new build. Will definitely buy again.
