The ZeroLok 15/15 is the longest handguard in the ZeroLok AR-15 lineup—engineered for shooters who demand maximum rail space, unmatched rigidity, and absolute control. Designed to pair with 16″ and 18″ barrels, this 15″ handguard gives you the space to run a full mission-ready setup without limits.

It features two Picatinny top rail sections for optic and accessory placement, along with an integrated offset red dot mounting platform—purpose-built for use with the 51Fifty Red Dot Riser. Full-length M-LOK slots and dual QD sling cups give you total modularity, while the patented ZeroLok ARCA interface anchors it all with rock-solid precision and zero movement under pressure.

For SPRs, full-length builds, and duty rifles that do it all—the ZeroLok 15/15 is the control hub your rifle deserves.

Command every inch. Zero flex. Zero shift. ZeroLok.
