Yeah, I own two of them. One full military I bought for $100 at the gunshow, and one sporterized that I bought for $170 at a gunshop. Considering all the work like mounts, scope modified bolt, and synthetic stock were done it was a pretty good deal.
The FR-8 is a 98 action. There is a sister rifle known as the FR-7 that's based on the weaker 96 action. You can tell at a glance as the 98 based FR-8 has a straight bolt handle, and the FR-7 has a 90deg bend. It also says "FR-7" or "FR-8" right on the receiver, which is a dead giveaway[;)]
The FR-8 is plenty strong for the 7.62 NATO, but the FR-7 may not be. Spain used a 7.62 reduced round at the time when they adopted the CETME so that full auto would be somewhat controllable. They desiged the CETME to work with either full or reduced rounds, and I'm not too sure if the idea really worked or what. The Japanese did the same with their "Type-64". Anyway, the FR-8 is a safe gun for any safe 7.62NATO type ammo.
The barrel is a hammer forged CETME barrel basically. The HK type flash suppressor is just that. It has the wire cutter device, 22mm GL capability, and will take whatever will go on an HK. There's a "gas tube" looking thing under the barrel. That's where your cleaning kit goes, and the bayonet lug. The front sight is eccentric, adjustable for elevation by screwing it in or out, and windage by turning it as well as the post is off-set. It's not a great windage adjustment, but it works good enough. The rest of the rifle is pretty much a Mauser 98. No drama there. The rear sight is welded to the receiver. It is a rotating disk that has various ranges on it and you rotate it to look through different apertures for whatever range. Short range is an open "V". It's sort of like a Canadian C1A1 sight in operation, but the sight picture looks just like an HK-91. They're very handy guns as the short barrel makes them fast acting. Accuracy is typical of a 98. The barrel's a really good one, the trigger is typical military, but it can be replaced by an aftermarket 98 trigger without any difficulty. I have owned many 98s, and the FR-8 shoots as good, or bad, as any of them. The sights are really cool though. I really like the way they work, and they're tough and easy to use. You could probably make one as accuarate as any gun, and still keep the barrel. The CETME hammer forged barrels are good.
I mounted an ART scope on my sporter. The trigger sucks still, so that's the next step (like I don't have enough gun projects going on), but it will really drill holes in paper. 100yd groups are in the mid-2inch range with the Federal cheapo red box stuff. Good enough for what I need it for, and I'm sure it will get better with a replacement trigger. My military one has a much better trigger, but I'm not hacking on that.
Prices for a full military one run about $225-250. I wouldn't think it would be worth much more than that. They are unique, but still just a 98 Mauser. If you have a chance to buy one in that range, I'd do it. I don't think they'll be a great collector investment, but they'll dry up sooner or later. The bottom line is they are an enjoyable gun to shoot. What more can you ask for a couple hundred bucks?
