Thread: Baikal 12g to rifle?

Keen to pick the brains of people more intellegent than me.
I've been thinking of doing a takedown rifle for a while, thinking of picking up a used baikal for a platform as a cheapish project, are some models better than others? looks like firing pin hole needs bushed and what is the best expoxy/ retaining compound to use. Looking to do something in 6mm, no bigger than 08 case size. Extractor doesn't look too bad.

Cheers
