Plan B Flash Comp 1/2–28
1/2–28 Plan B flash comp. Mounts a Plan B suppressor without timing. 4150 CMV steel, QPQ nitride, made in America.
Part no. PB-FC-1228
A flash comp cut for a 1/2–28 right-hand barrel thread, machined from 4150 CMV steel and QPQ nitrided to 68 RC. It does the flash-hiding job on its own and doubles as the mounting interface for a Plan B suppressor mount.
Timing is not required. There is no shoulder to index and no peel washer stack to build — thread it on and torque it.
Verify every interface before you buy. Thread pitch, muzzle-device geometry, suppressor bore and mount depth all have to agree. "HUB compatible" is not blanket approval — confirm the exact suppressor model against its manufacturer's current drawings. Installed, fired or modified products cannot be returned.
