M4SD-K AM Silencer

Description

The M4SD-K™ AM Silencer is a compact, highly durable, low backpressure 5.56mm suppressor constructed from Griffin’s proprietary Nickel 625X™ powder alloy utilizing state-of-the-art DMLS additive manufacturing technology. These K suppressors were adapted from Griffin’s aggressive R&D project to develop the full-size M4SD-3™ AM. Left handed shooters will benefit from the very low backpressure stack as well as right handed shooters. The M4SD-K™ AM is an ideal suppressor for end users desiring an extremely low backpressure suppressor in a minimal form factor thanks to its 5.22″ overall length.

These silencers are built on Griffin’s highly-versatile GATE-LOK® QD mounting system which is designed to interface with Griffin’s GATE-LOK® muzzle devices, as well as Colt-pattern milspec A2 birdcages. This extremely rapid mount locks into place on teh BFA groove of these types of muzzle devices, and is compatible with many AR-15’s equipped with A2 muzzle devices on the market today. Each GATE-LOK® silencer ships with a GATE-LOK® muzzle device in the event your A2 device is out of spec from the original Colt print. We cannot guarantee fitment with other manufacturer’s muzzle devices due to the wide range of tolerances accepted as “milspec”.

The proprietary, patent-pending Nickel 625X™ alloy showed in testing a ~68% increase in yield and tensile strength over additively manufactured INCONEL® 625 at 1200°F.  INCONEL® 625 is a commonly used suppressor alloy in current next generation military suppressors.  Additively manufactured Nickel 625X™ is stronger at 1472°F than INCONEL® 625 cold formed sheet material at room temperature.  INCONEL® 625 cold formed material provided adequate service in the last several decades of military suppressors.
