Being a defensive gun with minimal recoil, a flash hider was the preferred choice. Since there weren’t many options for 9mm AR muzzle devices, the Smith Enterprise Vortex was the only way to go. It proved just fine on my first build, enough for me to use again. Shooters complain of the “tuning fork” sound it makes but I couldn’t care less. There are now a number of 9mm muzzle devices currently available. I had harassed a salesman at JP Rifles for months until they released their 14.5″ “Supermatch” 1:10 button rifled, 416R stainless steel barrel. The JP Supermatch barrels are cryogenically treated for extended barrel life. Needless to say, I was really excited for this and swooped up a black teflon coated one the moment it hit the market. The BCM KMR was another product that was “hot of the press.” A blend of aluminum and magnesium combine for one of the lightest handguards on the market. 3, 6, 9, and 12 o’clock keymod rails allow for a number mounting options. I ordered a 10″ with plans to chop the barrel if I ever moved to a state that would allow me to SBR it. A BCM Keymod Vertical Grip complimented the rail and was position so I could still activate the Streamlight TLR-3 that sat in front of the Troy Fixed HK Front Sight.
