Only DS I can say was great was the mk1 air ranger, awesome bit of kit being reliable and accurate. This I think was down to a proper regulator ( dont think DS uses one now) and no elecs or gimmicks, so rather like a rapid and 100%, my only gripe was with a silencer fitted it was too long..

I also bought a mk2 AR, mk3 sporter and an Airwolf and none could match the old mk1
