Looks to be a late 80's kit, lightly used near unissued condition. It may in fact be unfired, there is zero corrosion or carbon inside the muzzle brake.
Everything but the barrel and receiver is included. All numbers match (the # on the bolt is hard to see but it matches)
Comes with 1 brown circle ((21)) magazine that is unissued, still has ink stamps, no wear on lugs.
cleaning rod, mag ouch and cleaning kit are included.
Muzzle brake is a zig-zag chrome lined unit.
