The rifles were made on contract for KLM, and had a combination of features specific to that run. No one feature was too crazy, but this particular contract run of rifles was a small batch, and thus rare. 16 inch barrels with no muzzle device, semi-auto only, takedown pins on a chain.
What makes this variant so rare?
