probably... they used to sell all sort of stuff for these guns. but fact of the matter is why would you invest 500 dollars in one?
In my case other than the buttstock extension, that rifle is as provided to the Russian military.
I still have the hammer and sickle box it came in..
like one of my friends was going to buy a Mosin Nagant, but then he was going to custom stock it, installa scope etc..
and I said you will still have a worse rifle that cost more money than if you went out an purchased a scoped Ruger American or a Mossberg Patriot or equivalent.
