We are just cresting the "haydays" of C&R
I've thought about this and while it's true that there will likely not be many more guns eligible for the C&R rolls in the near future, all is not lost.
I think we've just crested the best time in C&R. If you didn't get on the wagon, you still can but are running out of time to buy straight from the distributors at reasonable prices.
If you look around, you can still find $275 SKS, $300 K31, and $80 Mosins... but yes they are running low. Now who knows, the distributors could be artifically driving the market by slowly importing them and keeping the price artifically high. I also believe they sit in port in customs for many months before being released.
But the really good news is that now all of those millions of C&R that were NOT in the USA just 20 years ago, are here now in peoples hands. They will end up in garage sales, moving sales, online sales, etc. At least they weren't destroyed in Yugoslavia!
As to the price, people often daydream of that $100 SKS back in 1983... But forget that in todays dollars that is about $225... Not far off where they are priced. Sure, there were better deals when nobody wanted that Chinese junk. Heck my friends dad had one of those "junky" Chinese SKS in the attic for decades along with a crate of ammo.
But now they are popular, everyone understands they are good rifles. It's a double edged sword. Same is happening right now with the Mosin Nagant. That junky rifle when it was $30 is now $100 + and $200 for the carbine. The lesson is that you can't wait on these items.
30 years ago wasn't the hay day because, I imagine, researching C&R and buying online wasn't easy or an option. The sheer selection available probably wasn't like it either is today, or just recently was in the last couple years. While you may have been able to pick up any number of $200 M1 Carbines off the rack, you may not have been able to get much larger selection than that.
