The Timber Creek Outdoors Enforcer 13 M-LOK Handguard is a slim-profile, high-quality rail system designed for AR-15 rifle platforms. Precision-machined from aluminum and finished in Olive Drab (OD) Green, it features a full-length Mil-Spec 1913 Picatinny top rail and M-LOK attachment points at the 3, 6, and 9 o'clock positions. The system includes a proprietary barrel nut designed for a simplified installation that requires no timing or shims. Due to its slim 1.3 inner diameter, this handguard requires a low-profile gas block for proper barrel and gas system clearance. Note: This 13 handguard includes integrated QD (Quick Detach) sling swivel ports for streamlined sling mounting.
