    HBAR is not needed and will likely be a regrettable mistake. Unless you just want to build a clone you might be better served by a Recee barrel for use as a ranch rifle.

    Do you believe the twist rate was what determined your score or the ammo? Or the rifle itself? Perhaps the barrel itself was more conducive to accuracy. Im a big advocate of using what you have.

    I shoot a ton of 68/69/70 gr ammo through 1:7, 1:8, 1:7.7, and 1:9 twists.

    My most accurate rifle is a 14.5 1:7.

    Id agree with the above, those clones are quite long in the tooth.

    My most consistently accurate upper is a PRI built Douglas 1in8 SS 16", heavy for is length due to the MK12 SPR barrel profile (but shorter).
    This is an updated version much more handy (as in light) 18" Noveske SS SPR 1in7 that printed the group below @100yrds 77 IMI OTM. And as always YMMV...

    I’d skip the BCM barrels. White Oak is where I’d shop for a budget barrel that is more likely to shoot well. I’ve had a few of BCM’s barrels and was less than impressed. If you can afford $350 on a barrel, Proof Research Stainless barrels would be an option. A shooting buddy has a couple that hang with my Kreigers.

    Barrel quality, barrel to upper fit, and your trigger are more important than configuration if accuracy is your first priority.

    If you just want a clone mk12, buy from Centurion.

    Myself, Ive had poor experience with WOA. One barrel was lucky to break MOA and by 2500 rounds it was so eroded it shot out. I couldnt hit anything at that point. I dont like 2.5 MOA guns that much.

    My BCM KD4 is quite accurate and had held up well. My SS410 barrel is ok on a accuracy but still shooting great 5k in.

    What is your take on the KD4 7.7 twist?

    7.7 is considered by a lot of competition shooters to be ideally suited for 77 gr Sierra MatchKings. Ive used 70 gr TSX, 75 gr Hornady, 77 gr SMKs and 69 gr TMKs successfully with mine. I have also shot some 55 gr V-Maxes sub-MOA.

    Just proves that every barrel is different. I had a BA premium barrel that shot well but was toast by 1200 rounds.

    You could always do a Mk12 Mod Holland, which is a Mk12 that was re-barreled with a 16" Noveske stainless barrel.

    Pri mk12 Douglas barreled uppers have some great offerings a little dated but very accurate. I’m a little biased as my mk12 is my favorite rifle and a white oak car axle weight barreled upper is close. If you want less weight and accuracy go with a noveske you won’t be disappointed. Hope this confused you as much as it cost me the last couple years
