Description Aim7 1.375X24 (1 3/8X24) BOOSTER HOUSING 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 1.375×24, 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 hard coat anodizing. The thread pitch of the booster housing piston retainer nut is 1.125×28, 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 need a booster assembly to make their firearm reliably cycle when suppressed.
