Classic Unibody Green Bushmaster (not deluxe) barrel kit with bolt and sight rail (no hammer). Threads look good with some wear but good shape overall. Takes standard 2.25 inch bushmaster bore drop bolts, but has very early bushmaster bolt. Bolt has aluminum front and stainless back. Non adjustable. Sight rail screws look like they have never been removed. Has two valve body thumb screws. Please look at pictures! Has tape residue around feed neck.
