Re: Spanish FR8
Personally, I really like the looks of them. They make excellent shooters and truck guns. The back half of the rifle looks like a regular old Mauser, but the front half looks like a CETME. I think it's the original bolt action battle rifle! Most of these guns were used as trainers so most did not see any kind of action. They were a way to transition soldiers from the bolt action to the new CETME that was being built.
The FR-8 will be perfectly fine shooting commercial .308 ammunition, but the similar FR-7 is HIGHLY recommended that you NOT shoot .308 ammunition from it.
Most of the ones on GB are in rough shape, but occassionally you'll find one that is good quality.
