Forward Controls Design 6315KM-S Keymo Micro Mount - 1/2x36

6315KM-S, 9mm is a short Key Micro muzzle device for Dead Air Silencers 9mm sound suppressors. At 2.063" long, it's tiny compared to the 6315KM (2.4"). Like 6315 on which it's based, 6315KM-S 9mm has asymmetric ports to optimize muzzle rise compensation without creating obnoxious concussion and noise, its 3 and 9 o'clock ports are slightly smaller and shorter, the design forces more gas to be vented through the 3 upward facing ports. Compatible with Dead Air Silencers Key Micro 9mm sound suppressors. Specifications: Length: 2.063" Weight: 3.55oz (1/2 x 36) Proudly designed and made in Texas, USA. Please NOTE: 6315KM-S is made for 9mm barrels that typically have a shorter threaded section, it will not fully cover the threads on .223 barrels.
