PSA "Sabre" FN CHF CL 13.7" Mid-Length 1:7 5.56 Nato Barrel
The PSA Sabre FN CHF CL 13.7" mid-length barrel is built around the modern pin-and-weld carbine formula: a shorter-than-14.5" barrel length, mid-length gas, and a chrome-lined cold hammer forged bore. PSA lists the barrel as FN cold hammer forged chrome-moly-vanadium steel with a 5.56 NATO chamber, 1:7 twist, chrome lining, and MPI testing.
The 13.7" length is intended for builders planning a permanently attached muzzle device to reach legal rifle length, or for SBR and pistol configurations. Compared with a 16" value barrel, this is the more compact Sabre/FN CHF route with a stronger durability story and a higher parts cost.
