bought this gun from dicks. box says model 10fcpxp. its a 20" fluted barrel, oversize bolt handle, 4rd detatchable mag, barrel seems to have a nice crown, accutrigger, no accustock or hs im pretty sure. paid $649 and sold the scope for 50. my friend says its a fp not a fcp, but the box says different. also is there a place i can buy a larger capacity mag?
