I have noticed actual rare milsurps tend to not sell as fast or as high a price in comparison to many of the more common variants or hyped firearms (think M39, K31, M1 Garand).
For example I am trying to sell a Soviet produced M91 Infantry Rifle made in 1926 at the moment for 350$ shipped. Bore is still VG, it shoots great, and it is extremely rare because it is from the last year of production for a Soviet M91 Infantry. It has sat for 3 weeks at that price, well other mismatched, much more common Imperial M91s that have been heavily Finned are selling for more and faster.
What I think it is the fact less people are actual collectors and are more interested in having some milsurps rather than collecting them.
