i have both a mk 1 rapid 7 and a mk 2 rapid all though lovely guns to shoot the magazine in my opinion lets them down just to fussy slide the cover the wrong way and the spring in the mag unwinds this is a problem which should be addressed imo, unlike the air arms s410 i have which can be loaded easily even in pitch darkness i now have the s510 as well and i mainly use these when out on rabbit hunts unless i need the extra shot capacity of the mk 1 and mk2 rapids mini rant over
