AR-15 End Plates – QD, Ambidextrous & Mil-Spec Options
AR-15 End Plates – QD, Ambidextrous & Sling Mount Options
When you're building or upgrading an AR-15, don’t overlook the end plate—it plays a crucial role in both function and sling compatibility. The end plate secures your buffer tube to the lower receiver and often doubles as a sling attachment point, giving you stability and flexibility in one small but vital part.
At Mounts Plus, we offer a complete selection of AR-15 end plates, including QD sling mount plates, ambidextrous designs, and standard mil-spec options. Whether you're a tactical shooter, home defender, or competitive builder, we’ve got the right upgrade for your rifle.
Why Upgrade Your AR-15 End Plate?
Most factory ARs come with a basic end plate that gets the job done—but it’s not built for modern sling setups or demanding use. Upgrading can give you:
- More sling mounting options: QD (quick-detach) or loop-style
- Improved weapon control: Especially for ambidextrous or dynamic shooting
- Better fit and finish: Cleaner installation, fewer rattles
- Stronger retention: Prevents buffer tube rotation and wear

Frequently Asked Questions (FAQ)
Q: What does an AR-15 end plate do?
A: It holds the buffer tube and receiver together and often adds sling mounting points.
Q: Do I need a QD sling mount plate?
A: If you use a quick-detach sling, yes. QD plates make transitions faster and cleaner.

A: Some will, but not all. Billet lowers often require specially shaped end plates—check your lower's specs.
Q: Are these compatible with any AR-15 buffer tube?
A: Yes, most of our end plates fit standard mil-spec tubes. Always double-check if using commercial-spec parts.
