OK,
I got the barrel done today and made the muzzle nut with a 1/2-28 thread so that it will handle the US Standard sized .22 cal suppressor. I test fired and it works well with feeding and ejection pretty positive. The mag is a bit annoying as it holds only 5 rounds but its better than single feeding. I didn't get to shoot this eve without the suppressor due to the late hour I completed the parts. I'll try that tomorrow and see if I can get it printed on paper as well.
Here are a couple pics of the 06/29 with the conversion installed and also with the suppressor.
