Midwest Industries Heavy Duty Quick Detach End Plate, Black Finish MI-HDEP
The Midwest Industries Heavy Duty Quick Detach End Plate is a robust AR-15 buffer tube end plate built for shooters who demand reliability under hard use. Unlike stamped or cast alternatives, this QD end plate is billet-machined from 4140 alloy steel—a material choice that delivers superior strength and durability. If you're running a suppressor, running a sling, or simply want a bulletproof mounting point for your rear-mounted accessories, this is the no-nonsense choice.
The anti-rotation QD socket keeps your quick-detach systems locked in place without the frustration of loose bushings or creep. Weighing just 0.7 oz, it adds negligible mass while replacing the factory end plate. Midwest Industries machines every unit in the USA, and backs the design with a lifetime warranty—confidence you can count on whether you're at the range, in the field, or training hard.
Drop this end plate into your AR-15 build or retrofit, and forget about it. Heavy duty doesn't have to be heavy, and it doesn't have to be complicated. This is the kind of part that earns its place on a rifle through quiet reliability.
