FPM SSPL-556-58X24-SS-BLKDLC SPLEEN 556 5/8X24

Description

The FUQUA PRECISION MACHINING FPM Spleen 556 is a muzzle brake, threaded 5/8X24.

A muzzle brake redirects escaping gas sideways and rearwards to push back against recoil and muzzle rise. The gas it redirects has to go somewhere, so a brake makes the rifle louder and sharper for anyone standing beside it.

This part is threaded 5/8X24, which is the usual thread on .30 calibre barrels. Thread pitch has to match exactly – a near miss either will not start or will cross-thread, and a damaged barrel thread is a gunsmithing job.

A muzzle device fitted to bring a short barrel up to the legal 16 inches only counts if it is permanently attached – pinned and welded, or silver-soldered. Simply screwing one on does not change the barrel's measured length.

This is a part, not a regulated item. Mounts, pistons, caps and muzzle devices are not NFA-controlled and ship directly to your address – the suppressor itself is the registered item.
