Most barrels are made by 2 or 3 companies you never hear of, the ones you hear of are assembly companies or parts houses.
All makers can make good barrels it is how the the specs are written that make the barrel good or bad. I would stay away from barrels with 9.5 twist, 10 is ok, 11-12 is better. I would stay away from barrels with a 1/2-28 muzzle thread on a 6.8, 6.5 or 7.62x39 Many parts houses do not inspect the barrels at all and send out many with bad crowns, even some of the big name(high dollar CHF) barrels in 5.56 have bad crowns. The real barrel makers- Shaw, Wilson Arms(not wilson Combat), Shilen, PacNor/Noveske, Prices are all over the board but a $400 barrel doesn't always out shoot a $200 barrel. As for companies selling those barrels check out 68forums.com |

Why do you say to stay away from the 1/2-28 muzzle thread? Because of getting a bad crown on those?

Just like on the 5.56 if you relieve too much metal around the bore it allows the bore to expand an lets the bullet wobble as it exits the muzzle. A 5.56 bore should be .218 but on most 5.56s you can slide a .219 inspection pin in the bore apx 3/4" before it stops. The same length as the threads. The bore of a 6.5, 6.8 or 7.62x39 makes the problem worse due to the thinner wall around the bore. Bad crowns are caused by bad tool alignment in the crowning process like most CHF barrels I have seen or a dull carbide insert and then NO inspection by the barrel maker or company selling them. |

I would also agree w/ the prior post, if you need muzzle threads do not go less than 5/8 diameter.
You can try BHW they make excellent barrels for the AR-15 at a very fair price Including the 6.8 SPC Spec II caliber. They Inspect EVERY barrel before it leaves the shop...The cowns on my BHW barrels are always top rate. |

I would seriously suggest reading up in the 6.8 FAQ thread, and then head over to the 68forums to check out the info there as well...
As far as barrels go, Noveske, Bison, ARP, Wilson Combat and many others sell quality barrels from several barrel manufacturers. |

I have checked out the FAQs ... I just kinda wanted some people's opinion on it. I like the Noveske Stainless 18" W/Switchblock but seems a bit pricey.

Well price isn't a huge issue for me but its always gonna be some sort of factor. Typically it will be just for target shooting on at shorter ranges but I want to bring it to a long range and have good performance as well. I also want the ability to run a suppressor.

If you are looking for a SPCII and 11 twist 4 groove barrel the barrels used by Bison, AR Performance and Wilson Combat are exactly the same, same rifling button and reamers used by the same barrel manufacturer.

Tim_W & QuicksilverJPR!!!

A premium grade 18" stainless barrel, bore is lapped, our 6.8x43 match chamber, 5R rifling, mid length gas system. .800/.700 contour, 5/8-24 threaded muzzle with 11 degree target crown, combo includes a 9310 alloy bolt and shipping. Firing pin and cam pin NOT included Don't believe the hype, anyone can call any barrel a "match" barrel or "ultra match" what ever that is but are they really a match grade barrel?

I was actually just about to start a thread similar to this one. I have also read the FAQ, but my bottom line is this. I want a barrel for a "duty" or "working" type gun. Think general purpose, with a high volume of shooting and most of it being done from 0 to 300. The specs I'm thinking are:
-16" Mid-length gas system -Chrome Lined -SPC II -Prefer 1:11 twist, but 1:10 will work -Prefer 4 groove rifling, but that will not be a deciding factor (the above four points will be) Thanks! |

my 1:10 barrels will blow primers and show signs of overpressure with combat loads

Forget the chrome lining in a 6.8, you are asking for trouble. Melonite treated barrels are 70 Rockwell, it is not a coating it is a heat treat that makes the material 70 rockwell thicker than chrome lining can be. Melonite barrels should last twice as long as stainless barrels and are just as corrosion resistant. |

You can get a real match barrel from Rainier Arms for less money that will out shoot any 6.8 barrel made.
The premium barrels ARP is selling are lapped Wilson Arms barrels, great barrels and just like the ones WOA uses but made with ARP's rifling and chamber, they seen high not to be a true match barrels like a Shilen or Kreiger but they do come with a bolt so that makes up for some of the cost. I would get the Shilen 6.8 barrel and not look back, I have two of them and they are lasers. |

I like the lwrc, arperformance, and wilson are the ones I like
you have to be careful cause some parrot the twist and stop there. There is so much more to your barrel choice than just twist, you are building/buying a system and like any system, you want it all to match for optimum performance cold, break down the rifle that is blowing primers to me. I'll bet it's not the barrel but your throat or something else unless you own a noveske which prompted the change from combat to tac loads as the old noveske 1/10 and lmt barrels had issues with them. |

for the record, I own an lwrc and an arp so I may be biased with those pics but all my research etc pointed me in that direction.
you can't buy the barrel from lwrc, you would have to buy the whole upper. Arp sells just the barrels and you get to deal with the owner who is a superb cat! |

Kotonics went out of business due to some thick chrome lining in the 6.8 several years ago. It adds to the bore surface decreasing bore area which increases pressure. It is not as accurate as a Melonite barrel of the same quality. A melonite treated barrel will last twice as long as a stainless barrel. There are production grade barrels on the market capable of shooting 1/2" groups. Is it worth buying a "match grade" barrel for $100 or $200 more to get an 1/8" better group if that, most shooters can't shoot well enough to tell the difference. |
