Who This Is For
The Phase 5 SQD-EP is ideal for AR-15 builders and owners who want to add a reliable quick-disconnect sling attachment point without drilling, welding, or modifying their lower receiver. Whether you run a two-point sling for precision shooting or a single-point for close-quarters work, this end plate gives you a low-profile, rock-solid QD socket at the perfect ergonomic angle for right- or left-handed shooters.

Frequently Asked Questions
Will the Phase 5 SQD-EP fit my mil-spec AR-15 lower receiver?
Yes. The Phase 5 Sloped QD End Plate is designed as a direct, drop-in replacement for the standard AR-15/M4 end plate and is compatible with any mil-spec buffer tube and lower receiver. No drilling, tapping, or permanent modifications are required — simply swap out your existing end plate during assembly or a standard buffer tube installation.
What type of QD sling swivel is compatible with this end plate?
The SQD-EP accepts any standard quick-disconnect (QD) sling swivel that uses the industry-standard push-button QD socket format — the same type found on most modern two-point and single-point slings from brands like Magpul, Blue Force Gear, and Viking Tactics. The 360-degree rotating socket ensures you can position your sling for a comfortable, snag-free carry regardless of shooting hand preference.
Do I need a special castle nut to use this end plate?
No special castle nut is required. The Phase 5 SQD-EP works with standard mil-spec castle nuts. When installing, torque the castle nut to the recommended specification (40–80 ft-lbs) and stake it in place to prevent loosening under recoil, just as you would with any standard AR-15 end plate installation.
