Say you were going to re-barrel your AR with the intent of shooting 77 TMKs around 2700-2800 fps into tinny little groups up to 500 yards. What would you spend your money on?
Douglas (if wanting mk 12 clone) Noveske, Larue, DD, BCM. I have mk 12 Daniel defense I built to crane specs otherwise that shoots 0.4 MOA to 800 yds with 77 TMK.
Not a Google expert with basement mold on his azz^^^^^
heed this,,,the man knows that which he speaks
I understand, but I’d like my AR to shoot them. Slightly under MOA consistently would be acceptable to me.A cheap savage bolt gun.
1-9 twist with a 22” barrel chambered .223
Which I like to think of as a match 5.56 barrel.
my buddies stag arms gun heavy 24” 1-8 twist shoots them well but my savage bolt guns print them tighter. It’s going to be tough to get an accurate AR platform barrel IMO. Green mountain makes a good one.
It’s all about chamber dimensions IMO
If an 1” at 100 is good enough you shouldn’t have a problem.
the custom m4 seal sniper rifles don’t hardly print them under an 1”
cheers
I’m no expert but I have spent a lot of time behind the mk262 mod 1 round
my best groups are .5 moa at 500yds with it. 2.5” or so.
Anybody shooting a LaRue Stealth? Is the 1:8 enough to stabilize the 77s out of a 16 or 18 inch?
This bullet requires a barrel twist rate of 1×8” or faster.

What’s wrong with you? Freak.Don't own any rifles. Sorry
Have you ever had trouble getting the 77 TMKs to stabilize in a 9 twist? I came into a gift certificate for Christmas and may be looking into a bolt 223.A cheap savage bolt gun.

Someone you know intimately?Satern cut rifled. Ranier arms ultra match. McGowen. Ranier arms match. White oak.
This addresses most budget concerns. It is almost the most expensive to least(ish) but more so is in the order of my preference.
Personal experience with all the above. Get what the budget allows but don’t fret too much. Heck I’ve got two er shaw barreled guns that are absolute shooters. That being said my shaw barrels and the mcgowen were turned by a shade tree machinist/gunsmith. He’s an a$$hole to deal with and works very, very slow but I could afford him. He don’t do much gun work anymore though just a bunch of knives………………
A 1:9 won't work well with the 77's. Even a 1:8 is questionable, but depends on the specific barrel manufacturer - some 1:8's will shoot 'em just fine, some won't.Have you ever had trouble getting the 77 TMKs to stabilize in a 9 twist?
