Ballistic Advantage AR-15 Logic Series M-LOK Rail Features The Ballistic Advantage Logic Series handguard is built around a full top Picatinny rail for mounting optics sights or other accessories along the entire top of the receiver and barrel. Seven sides of functional M-LOK slots give builders near total freedom to attach lights grips bipods and other accessories wherever they are needed on the handguard.

Quick disconnect sling sockets positioned at the 3 6 and 9 o clock locations give shooters multiple sling mounting options without needing to add aftermarket sling adapters. The handguard is compatible with low profile gas blocks and features a 1.381 inch inside diameter with a 1.53 inch outside diameter keeping the overall profile slim for a comfortable grip. Fitting standard AR-15 platforms at 15 inches in length this handguard gives builders ample real estate for lights optics and other accessories on a carbine or mid length build.
