About Robinson Arms XCR Compatible Accessories

The Robinson Armament XCR has a dedicated following, and A3's HDA3 line fits it directly: the hybrid polymer stock, the hybrid polymer brace, and the HDA3 adapter that mounts either one to the XCR receiver.

Every XCR product is fit-checked against the XCR interface. The firearm-adapter variant on modular products locks that interface at checkout so the correct hardware ships in the box.
