Thinking about mocking up a MK12 upper for my AR for longer range desert shooting and coyotes. My problem is that I can't find any barrels tighter than a 1:8 twist and my question is will a 20" barrel with a 1:8 twist stabilize a 77gr match grade bullet?

Re: MK 12
just go 18.5" mk12 barrel from high caliber sales or centurion arms they are designed for 77's and shoot them really well.

White Oak has the best price I've seen so far and looks to be exactly what I'm looking for. Next question is (and this might make me sound like dumb ass) will it handle the MK262 round in the chamber?

1:8 twist is fine for 77's. Some shoot them out of 1:9's. MK262? If it has a 556 chamber then technically yes but that doesn't mean it will be accurate. Better off making up your own handloads imo.
Rainier has WOA barrels in stock, Bravocompany has some stainless 1:8 offerings that might interest you too.

Re: MK 12
FWIW, i'm running a noveske 18" on mine (1:7) and it rocks. It came from Ranier arms. I will probably use a WOA on my next one just for price though. Both are great, as are the options from high-caliber sales, ADCO, etc.
