EXCELLENT! it is a fine gun, fired over 1,000 rounds through it, and .223 ammo aint too cheap =(. But it has never jammed once. i bought a dragunov style stock and a 30 round clip and put a scope and bipod on it. They also sell a 6.8 spc. version of it, its fairly new. they also sell a mini 30 which takes 7.62x39 i think. then the smaller version...the ruger ac556...now thats some eyecandy, 15 round clip full auto mini14 looking pistol grip eyecandy!
