Knights Armament Rifle Lowers for Sale

Knight's Armament Company of the United States made its rifle lowers a signature element in 2011 with the debut of integral ambidextrous controls on SR-15/SR-16 E3 rifles, and by 2013 it was selling SR-15 lower-receiver assemblies on the commercial market while continuing to refine the design across SR-15/SR-16, SR-25, and KS-series lines. KAC rifle lowers are distinguished by fully mirrored ambidextrous controls that include a bilateral bolt catch/release alongside ambidextrous magazine release and selector, with complete lowers typically configured as duty-grade assemblies featuring a two-stage trigger and QD end plate to emphasize ergonomic manipulation and professional-use reliability.
