Condition report:
The rifle and its accessories are in overall excellent condition. The black metal finish is well-preserved with only minor handling marks on the receiver and light surface scuffing on the drum magazine. The green polymer furniture remains attractive with minimal wear and no significant scratches. The bore is bright with sharp, well-defined rifling. The action appears to function correctly, though we have not live-fire tested this firearm. The folding bipod locks securely in both the stowed and deployed positions. The belt-feed mechanism is clean and the included ammunition belt links are free of corrosion.
