Description
These 17-4 H900 booster pistons are in the pattern we have coined as BPISTIN, a homophonic acronym which stands for:
Booster Piston, Industry Standard Ten Index Notch
They will fit:
-All ECCO Machine booster assemblies and pistol suppressors
-All SilencerCo booster assemblies and pistol suppressors
-Rugged Obsidian 9 & 45
-Dead Air Odessa
-OSS Rad 9 & 45
-Current YHM booster assembly
Though nearly identical and able to install in Griffin boosters, Griffin pistons have a slightly larger flange, so the BPISTIN pattern will be sloppy in them and may cause detrimental misalignment.
1/2-28 and 5/8-24 pistons are through-threaded, all others have a muzzle register at a depth of .43″/11mm.
