Description
AMD-65 extended muzzle brake in 4140 steel, threaded 14×1 mm LH, overall length 4.3″, weight 7.1 oz, with a .417″ opening. Built to bring an AMD-65 barrel to 16″ when configured appropriately. Made in USA and counts as a 922(r) compliant part.
- Thread: 14×1 mm LH
- Length: 4.3″
- Weight: 7.1 oz
- Opening (Aperture): .417″
- Material: 4140 steel
- Design heritage: Based on Hungarian two-piece pattern (body + threaded insert); machining gap at the cone is correct to originals
- Compliance: US-made; counts toward 922(r). To reach a legal 16″ barrel length, permanent attachment may be required where applicable—verify local, state, and federal laws.
Manufacturing notes: Bodies and inserts are CNC-machined; like originals, the threaded insert creates the internal chamber for proper braking action. The visible gap at the cone matches original AMD-65 brakes.
