When I get a milsurp rifle, I tend to want a pig-sticker for it.
I have a 'Nam era M16 clone, $700 for the parts for the rifle, $40 for a bayonet.
M1 Garand, $1,000 for the gun; $45 for the bayonet (reproduction).
FAL, $1,500 gun; $30 bayonet.
Soviet Mosin-Nagant M-1891/30? $100 gun and the bayonet came with it.
Finnish Kiv/28-30? $150 for the gun, $450 for a bayonet!
Finnish Kiv/39? ≈$150; bayonet $600+!
I've never seen this situation before.
