The Phase 5 Sloped Quick Disconnect End Plate (SQD-EP) was designed to replace the standard AR15/M4 carbine end plate. While still meeting the requirements of the original design the SQD-EP is lighter and QD Swivel compatible. It accepts all push button QD swivels and QD slings. The end plate mounts at a 30 Degree angle from the lower receiver to allow a 360 Degree rotation for ambidextrous use. The Sloped Quick Disconnect End Plate is constructed of billet 7075-T6 aluminum. Made in the USA.
