Thanks smellie, mle, the FR8 is a 98 Mauser action. The 1916 model Mauser shown above, is a 93 Mauser action. Not nearly as strong as your rifle.
When NATO concerns were raised as to the Spanish CETME semi auto rifles that they couldn't operate without being damaged with standard NATO loads, the Spanish just used heavier springs to accomodate the NATO pressures. The US got several shipments of these fine rifles. Canada of course, because of their full auto capabilities didn't get any. We did get thousands of other Spanish offerings. Some of it was as new, like the sweet little carbines with the 18inch barrels that were converted to 7.62CETME, the 1916 shown above, FR7, FR8 as well as K98s in 8x57 and M91, M93 rifles in 7x57. A lot of them were FTRed and as new. Many were beat to death and barely considered fair.
The ops rifle is very nice but it is a weaker action and should be treated accordingly. To compare it to an FR8, is like comparing your 250cc ATV to my 650cc ATV. OOPS, that ATV comparison should be the other way around.
