I received my Cross today. The fit and finish seems to be pretty good. I like the trigger. Removal of the handguard was easy. The barrel nut and extension nut were tight. I added a M-Lock Arca Plate and a bipod stub. Those parts fit the rail well. I stripped the scope off another rifle because I haven't received my scope yet. My TBAC 338U is on it but I think my Ultra 7 will be used most of the time.
