The bluing on the rifle is excellent and the parts are matching. The barrel is threaded. The weird knobs on the trigger retaining pins are for the scope mount which is inluded. it currently has a magpul moe pistol grip on it. You can get some replacement retaining pins for $10 or so to give it a more traditional look. This is one of the spikers that was caught in customs in 1994 that got its bayonet ground off. These when fully restored run around $3300. This is in great piece to any collection and a tremendously reliable rifle for anyone wanting a hyper reliable rifle. $2200 obo (ThreeSixOne) 54nine-98eight4
