Centurion 14" C4 Midlength Front Sight Pocket Rail Handguard - 0609-14P

Upgrade your AR platform with the Centurion C4 14.25″ Free-Float Rail — a patented, two-piece rail engineered for maximum rigidity and minimal weight. Machined from 6061-T6 aircraft-grade aluminum and finished with Type III hard-coat anodizing, the C4 system clamps to a standard barrel nut to create a continuous 12 o’clock Picatinny (1913) rail without removing the front sight or permanently attached muzzle devices. Its precision design delivers an exceptionally stiff mounting surface for optics and accessories while keeping overall weight low, making it an ideal choice for duty, competition, or precision AR builds.

The C4 installs on MIL-SPEC uppers; some billet uppers may require modification to accept the alignment tabs (modifications void returns). The rail’s internal pocket accommodates a mid-length front sight post, and the system ships with Grade 8 fasteners for secure, repeatable lockup. For reliable results and to protect your warranty, gunsmith installation is recommended.
