Centurion Arms CM4 16” 5.56 ballistic advantage barrel If you know Centurion Arms you know they are solid battle rifles!! Rival that of bcm, solgw etc..This rifle is loaded with Forward Control Designs parts, including their dual selector switch, bolt release, charging handle, forward assist, mag release, and their twin dimple (green) ejection port cover. Loaded also with SOLGW bolt carrier group, and a Geissele SD-C combat two stage flat trigger! Magpul bipod includes as well. If you know, YOU know what quality components are on this rifle!! Also the muzzle is the Dead Air NOX flash hider. I had the rifle professionally built by a certified armorer and it works flawlessly!! Super low round count, i believe a 100 rounds total to zero it and get it dialed in. Love this build but it is not being used and has been in the safe since i zeroed it. Will sacrifice it for 1250.00 because im impatient and am doing something else now! Guitars ain’t cheap son! 😉😂 $1250.00 text or call 208-713-5863
