Part #s match (barrel, bolt, carrier, gas tube...)
Heavy finish wear, but otherwise it looks great. Bore also looks great. Strong rifling and mirror finish.
Markings show an 11 in a circle, with 1979 next to it. gas piston looks brand new and chromed... no carbon on it.
The upper handguard is so dark, it looks like baklite. I can't tell if it's wood or not! What IS it? Is it just laminated? It looks like the grain runs around it, not forward and back.....and the edges are crisp like bakelite too... but I just can't tell without removing it.
