Bolts and barrel ques

[cowboybart]

Thanx for the input. The BHW barrel is marked .135 headspace. The Saturn barrel is for a Gren II, which I believe is a .136 hs also. I thought about deepening the bolt, but then thought of all the stuff that I would need to adjust to make it right. That's why I opted for deepening the chamber. Looking at it now, the LH Maxim bolt looks like the way to go. Maybe I can make another upper in 7.62x39 with the bolt, if trying to sell it fails.
