Its very simple if your used to it. Like I said Im used to my XCR. The XCR is designed around never having to take your trigger hand(for me my right hand)or eyes off of target. Drop mag with right index finger, insert new mag with left hand, charge bolt with left hand, release bolt with right index finger, never removing your hand from the grip. The RFB of course does not have that nice ergonics being its a Bull Pup but still for myself I prefer to charge with my left hand. The entire rifle is designed to be ambidextrous tho.
