I've shot a friend's AC556K with the Ciener conversion kit and it ran very well with
no mods. That's generally the experience most Ruger owners have with these kits. Anyway, I haven't seen an actual Ruger Ciener kit out side of a gun so I don't know how similar they are or if this would work or be of any help.
It's used primarily as a anti-bounce method and one byproduct is a small reduction in the ROF. It's not huge so don't expect big things. A .22LR doesn't have much power to begin with and anytime you start jacking with a conversion kit, both good and bad things may occur. IMHO, If you have one that runs, be happy and accept the ROF.
Hope

Helps.
