The ZeroLok 10/19 is the ultimate ARCA handguard for AR-10 platforms—measuring a massive 19 inches, it’s the longest available and built for those who demand total dominance over their rifle’s front end. Designed for 20″+ barrels and extreme long-range setups, the 10/19 offers unmatched real estate for mounting optics, bipods, night vision, and every tool in your arsenal.

With a full-length Picatinny top rail, M-LOK slots from end to end, and dual QD sling cups per side, the 10/19 delivers limitless versatility in a rigid, lightweight chassis. At its core is the patented ZeroLok ARCA system—ensuring zero flex, zero shift, and rock-solid consistency under the punishing recoil of full-power rounds.

For the shooter who refuses compromise and demands the absolute best—this is your foundation.
