This is a Swiss K11 Carbine, the precursor to the later K31 carbine. It is very similar is every way with the straight pull bolt, magazine, sights and trigger but has subtle differences such as the bolt design and overall length. All serial numbers match including receiver, barrel, stocks, magazine and bolt (even the front sight block).
Exterior wise, the bluing is great overall (90-95%) and the walnut stock is VG+ with some typical nicks and dents. The bore is amazing with a mirror shine and razor sharp rifling! Muzzle is good with no counterbore and includes brass muzzle protector.
$600 in central NJ / Jackson area and will meet at a FFL in a reasonable distance away.
Also have a few sealed bricks of GP11 available separately if you need some ammo.
