FR7's are small ring mauser actions coverted to 762x51nato. There is debate wetherthese are safe or not... The FR8 is built on a mauser 98 action and will hold what ever you stick in it.
The FR8 has a straight bolt, but there has been some seenwith bent bolts that are matching and very very hard to not say it was done at arsenal. The sites folks have issues with cuz one, as said you can rake yer thumb /fingers across teh nocth and cut yerself, sites are 100 open v, then 200-300m and the 400m is the one by itsslef. if sighted in correctly (25m with the 200m peep) all 4 sighst should be dead on. these are some of the hnadiest lil 762x51 carbines out there. only porblem is they only shipped them in once,, and thats it. what you find will only go up in price,, hell they are damn near over 300$ already!
sorry fer typos shitty keyboard at our office....
