Have a mk1 old crown. Was thinking of changing calibers and buying an updated kit. UNTIL I saw what the crown super lite system consisted of. Basically a liner stuffed into a transfer port covered by a shroud. Seriously? I guess it must work but quite honestly seems like a joke to me. I’m leaning toward just buying any other fx barrel kit and using my mk1 shroud. What have your experiences been like with the ultra light system ?
