The heart of the rifle is the L89 Drivelock handguard, which uses a titanium barrel nut and a specialized locking system to ensure that rail-mounted aiming lasers and optics maintain a perfect zero even under heavy abuse. Outfitted with the A5 Buffer System, a Liberty Fighting Trigger, and premium B5 Systems furniture, this rifle is built to exceed professional requirements for accuracy and long-term durability.
