The Midwest Industries Alpha M4 Beam transforms standard carbine stocks into folding configurations without compromising structural integrity. This steel folding adapter maintains proper cheek weld positioning while providing compact storage and transport options for tactical applications.
What Makes This Different
Unlike basic hinge adapters that create wobble and misalignment, the Alpha M4 Beam utilizes a precision-machined steel construction with tight tolerances. The dual-locking mechanism prevents lateral movement during firing cycles, maintaining consistent point of impact. This adapter integrates seamlessly with existing mil-spec buffer systems without requiring permanent modifications to the host firearm.Key Features
