It seems to me as though they're a bit like the non firing L59 DP rifles in that they're not real shootable rifles but every true collection ought to have one in it as an example. Just so long as the cheap (?) price justifies adding it to your collection

We have a Khyber Pass AK-SU at Warminster that is truly dire but it's good to pass around and fits into the AK story. As I mentioned above, ours was pretty cheap - we just took it!
