Nordic AR22 conversion kit for 10/22 ruger

[Mendocinokid]

Has anyone tried one of these Nordic AR22 conversion kits for their 10/22 ruger. I was thinking about tring one but first convering my 10/22 ruger to a 17 HM2 then using the Nordic AR22 conversionkit.

Here is a wedsite with instructions on the Nordic AR22 conversion kit
