I think you're right, it was mac's BC. I still have a copy of that pic in my PC at home somewhere.
Yes, quickdtoo has a set.. ...well at least had a set til just a couple mins ago.
I just scarf'd them up.
I'm really psych'd up right now. Gonna order the .223 Ultra 24" bull/heavy rifle today at lunch for this wood to go on.
I also have something going on with reamer and die manufacturers for a rechambering of it. And, the outside of the barrel itself might get some sides added to it in my uncle's machine shop. Then to top it off, I'm gonna flute the flats of the side.
I just haven't decided on which to rechamber to.
