Phase 5 Sloped Quick Disconnect End Plate (SQD-EP)

It’s hard to get excited about an AR-15 end plate. But as QD attachments became increasingly popular, it was clear that the standard end plate would need to be redesigned to include a QD Mount option.  When Phase 5 Weapon Systems Inc introduced the Sloped Quick Disconnect End Plate (SQD-EP) a while back, it instantly rectified the design flaw that the first round of industry QD Mount End Plates had – users found that the location of the mount limited the rotation of the sling attachment, causing the rifle to hang at an uncomfortable angle.

By angling the QD Mount out and away from the rifle, the sling attachment no longer interfered with the buffer tube.  Since the QD mount is at a 30 Degree angle from the lower receiver, it allows a 360 Degree rotation for true ambidextrous use.
