FN 14.5" SOCOM Barrel w/ FSB — CAGE Code Stamped, Pinned and Welded
This is the real deal: a genuine FN Herstal 14.5" SOCOM profile barrel assembly with factory F-marked FSB (Front Sight Base), cold hammer-forged from chrome-moly-vanadium steel, chrome-lined bore and chamber, and stamped with a CAGE code — the NATO Commercial and Government Entity marker that confirms its provenance as a mil-spec contract barrel.
Charlie's has pinned and welded an A2 extended flash hider to bring the overall barrel length to 16.1", making this a rifle-legal configuration for the civilian M4A1 clone builder who refuses to compromise on provenance. This matches the barrel assembly specification installed on M4A1 Block II rifles fielded by USSOCOM and conventional forces from the early 2000s forward.
Specs: 1:7 twist, 5.56 NATO chamber, M4 feed ramps, carbine-length gas system, .750 gas journal, F-marked FSB with taper pins, and factory M4 barrel extension. Hard-use chrome lining delivers the service life and corrosion resistance expected of a GI-issued barrel.
Supply of CAGE-marked FN barrels is finite — once these are gone, the clone community will be left with commercial substitutes.
