CMT Plan B Flash Comp 5/8-24
5/8–24 Plan B flash comp. Mounts a Plan B suppressor without timing. 4150 CMV steel, QPQ nitride, made in America.
A flash comp cut for a 5/8–24 right-hand barrel thread — the common .30-calibre thread — machined from 4150 CMV steel and QPQ nitrided to 68 RC. It hides flash on its own and serves as the Plan B suppressor mounting interface.
Timing is not required. No shoulder to index, no washer stack.
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.
