Description

These booster assemblies install in your 1.375-24 Bravo (HUB) threaded suppressor to allow the use of CGS pattern 12-tooth booster pistons.  They are NOT compatible with 10-tooth BPISTIN pistons.

They are also female threaded for Alpha pattern accessories, including Griffin Cam Lok 1.125-28 Direct Thread adapter, Griffin Plan A Alpha, SilencerCo AC2447 & AC2448 3 lug adapters, SilencerCo ASR Alpha, SilencerCo (Alpha) Harvester 300 Direct thread adapters, Q Plan B Alpha and others.

The housings are made from 17-4 H900 stainless steel, the retainer caps are 6Al-4V Gr. 5 titanium. Piston weights vary, but total weight with piston & spring installed will be ~3.3-3.8 ounces (D-Cell assembly is 4.5-4.8, depending on piston).

These assemblies include booster housing, retainer with O-ring, and spring. They DO NOT include a piston, but you can add a piston in the drop down here: https://www.eccomachine.net/product/booster-pistons/
