Banish 45 booster specs:

Overall length w/cap: 2.16″

Flange length: 1.5″

Flange diameter: 1.37″

Thread tenon length: .53″

Weight W/O piston: 4.2 oz.

Distance from flange shoulder to front of booster: .53″

Due to the external design of the Banish suppressor, the piston indexing notches for BPISTIN pattern pistons have to be drilled just ahead of the mating flange but behind the threads.   A 1-1/16 x 1/16 or 27 x 1.5mm Silicon O ring in a shallow groove is used to seal this connection, but the indexing notch holes will still vent into the threads, so judicious application of a synthetic lubricant like thick silicon grease is recommended to suspend the carbon and prevent difficulty removing the booster assembly.

 

Piston shank protrusion behind cap (all boosters): 1/4″ with standard 2″ long piston.

 

Though we sometimes have SOCOM black assemblies on hand, expect color options to add 5-10 business days to ship time.

 

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/
