Possibly ex-Israeli .308s. Since the Israelis are dumping older surplus weapons, it may be possible that these are part of that lot. If this is the case, they are either early post war Czechoslovakian made 98s or later FN made guns.
Would have thought so, but that's it...
Can't post a link because it requires a dealer account to view it in their "U-Fix-Em" section.
Edit: Those say "coming soon", not available yet. But I did just buy one of the Czech BRNO K98K's. I'm hoping it at least comes with the bolt, it'll be worth the price for the action alone. Like rolling the dice...
I saw it listed at Century website too but not brave enough to buy one. Many Israeli .308s went to South America countries, bores could be in pretty bad shape and receiver pitted under wood line.
