M4SD II 5.56 NATO SILENCER

Forged in the fires of Mount Doom, the new M4SD II (Mod 4) begins life as over ten inches of 17-4 stainless, tool steel, bar stock. We have found 17-4 to provide markedly superior wear resistance, as compared to softer high nickel alloys of good reputation in industry. The heart of the M4SD II suppressor is a billet machined "chassis" (tube body), with integrated muzzle device bearing surfaces, which houses the internal components. The "chassis" provides a housing substantially stronger than the strongest tube materials currently available. Through extensive, costly and time intensive machining of the "chassis", a tube structure of superior geometry is derived. The chassis is encompassed by a series of flutes surrounded by supporting structures affording enhanced strength to weight ratio- coupled with a 40% increase of surface area for unparalleled cooling. The M4SD II has surface area comparable to 7.62mm suppressors on the market.
