Just my opinion but I'd go with LWRC and get one of their Six8 rifles if you want a factory built gun. Even better would be to buy one of their Six8 receiver sets and build one exactly to your specs/preferences. Pricier than most, but I think having a receiver and mags that are designed specifically for the 6.8 ammo is worth the cost.
Barrett and Wilson Combat also make 6.8 complete rifles. I'm sure there are others too. |

I agree, if I was buying a factory 6.8 rifle I would get a LWRC Six8.
Both of mine are home built and use barrels from the company we don't talk about. |

The above is good advice. In order to use the advantage of the Six8's longer magwell, we need metal mags.
The Magpul-specific mags don't give you any extra COAL. |

With the standard mag well you can only use metal mags, so far that isn't much of a disadvantage. Reloaders like to push the OAL of the cartridge for a bit more accuracy and speed, for a shooter it's an expensive upgrade. Purchase a barrel with the correct spec chamber and all is good. You get what you pay for after that, within reason. Be advised that 6.8 is 50% more powerful than 5.56 so a heavier buffer is needed. Case in point, I built a 16" rifle with mid gas and rifle buffer setup, changed to a carbine with carbine buffer, and it started immediately double feeding. Changed to an H3 buffer and it stopped, loading correctly from then on. Bolt speed was too high and it wasn't ejecting, then tried to feed both into the chamber. Slowed it down and no further problems. I got my rifle back. It's usually best to choose a heavier buffer and to use the longest gas system for the barrel length practicable. So, 16" mid gas is a good choice - avoids the pin and weld etc - and you also get a plus with about 50 fps improvement over a 14.5". No complications. Select for dwell time, which is gas port location - and lower bolt speeds - which enhances reliable feeding - and you get a good result. |

I have 4 6.8s, a 20 inch from he that shall not be mentioned, a first year release from DPMS which is a 16 inch barrel that was rechambered to SPCII, and a 18 and 12.5 inch Cardinal/Kotronics (company went out of business but made some really great 6.8 barrels). Only the 12.5 inch Cardinal/Kotronics needed a heavier buffer to slow things down, the other three work just fine with standard buffers and buffer springs.
Of the four, the He that shall not be mentioned barrel is by far the most accurate although all are pretty darned good and all have been 100% reliable. Also, all 4 have the He that shall not be mentioned specialized bolt and I use that particular 6.8 bolt in all my 6.8 wildcats, 5.56 x 42, 6mm x 43, 6.5mm x 43, four .30 HRTs , .338 Spectre, and my own .338 GRRR. You won't find a better and stronger bolt anywhere IMO. For mags, I use PRI 6.8 metal mags which allow for 2.300" COAL or you can get a PRI mag that has the front cut out of it for longer seating if that's your end game. I have one load in the 6mm that needs longer COAL and I cut the front out of a Lancer AWM so it will load five rounds seated to 2.325 IIRC and it works just fine, but only for 5 rounds then forgetaboutit. |

I am at the point of shooting mine but have to come up with what buffer and spring to use.
Mine is going on a rifle length stock. I have carbine, H buffer, and rifle buffers on hand. I have an adjustable gas system. If I can swing it I am going to use the rifle and a tubb chrome silicon spring. Not sure it will work but that’s in the lower now for my NM upper. Would be nice to have that work and one less thing to swap. Mine too is a 16” unmentionable. |

You asked about factory rifles. It would be worth checking out Rock River Arms . My first 6.8 purchase was a complete upper from RRA. I’ve been very happy with it. Have several different 6.8s now including one I built using a bolt and 12.5 barrel from the previously not mentioned guy. Great caliber , it has become my favorite deer cartridge.

I have 2 6.8 rifles and 1 pistol. Both rifles sport Daniel Defense bolts and barrels. The pistol has a Wilson Combat barrel.
I've been getting Barrett mags off of GunBroker when I see the auction closes around $18-20 per mag. Been thinking of doing a 20" barreled rifle. But in no hurry. |

I built a 6.8 about ten years ago using a 16" barrel from the
company we can not name. I've been pleased with it. Last year I assembled a pistol using a Wison Combat 11.3" barrel. I really like the size or it, may SBR it. If you are set on a factory rifle Daniel Defense use to sell some nice looking 6.8s under the "Ambush" name. Not sure if they still sell them. |

I have 3 6.8 Ar's. One is a 16in Rock River upper. It's a light weight coyote and deer rifle. Nice shooter and fun to carry
One is an 18in DMR with a Kotonics barrel. Very accurate. I used it in a precision rifle class and it was deadly out to 600 yards. Even made hits out to 1000 but that was a little tougher. 3rd is a 14.5 LWRC M6A2 using the pre-Six8 receivers. Set up as a SHTF carbine with a TA33. Even with the ACOG it will shoot 1 inch groups at 100 yards with 90gr Gold Dots. I also have an 18in Custom shop barrel for my TC Contender. That's a sub 5lb deer slayer. My dad has a slew of 6.8's from CMMG and Noveske. Shooters all. I'd like to pic up a Barret Rec7 2 but that's spendy. Anyway, I definitely recommend getting a 6.8. You wont go wrong with LWRC or Barrett but something from Rock River or Stag will do just fine as well. |

I did a lot of reading over on 68forums before getting a 6.8 upper years ago. The un-namable along with Wilson and Bison got good reviews there. I Went a different route. At the time you could get a complete 20" upper with a FN CHF barrel at PSA . I went with the PSA upper for an A4 build. It shoots Hornady 110Gr really well. Unfortunately PSA has been hit or miss on availability of 6.8 uppers/barrels over the years.
If I ever build another 6.8, I will go with a shorter barrel and probably carbine or mid length gas system. The rifle length gas system doesn't seem to like the real light 6.8 bullets. |

I have 6.8s made by PSA, a piston LWRC plus barrels from the one who can't be named on this forum. The barrels from one who can't named are my most accurate 6.8 barrels. With my reloads, .5 MOA. My PSA is slightly less accurate and the LWRC Six8 is the least accurate But, I haven't spent much time working up a load for it. I like the LWRC Six8 and the Six8 Pmags. But not a big fan of piston ARs. I have several Six8 receiver sets that I use for other calibers, like .224 Valkyrie and 6.5 Grendel. Although the Six8 mag is larger that a regular metal mag like PRI's excellent 6.8 mag, you won't gain in OAL with a Six8 mag due to thicker plastic.

Don’t buy a factory rifle unless you definitely must have the LWRC Six8platform.
Personally, IMHO the way to go is build an upper with a barrel from the maker we can’t name. Also get one of his bolts. Then buy PRI mags. You’ll have a 6.8 that shoots most factory ammo with good to very good accuracy, and can shoot handloads with extreme accuracy. PRI mags are pricey, but built like a tank and just plain work. Note, if you go this route there is a downside. You won’t be able to up your post count with threads like “My 6.8 rifle is undergassed” or “My 6.8 won’t group” or “My 6.8 mags won’t feed”. |

I got into the 6.8 years ago by picking up a 16inch Kotonics upper on the EE. I was skeptical about the accuracy potential of a chrome lined barrel but shouldn't have been, it's extremely accurate and does pretty much the same with whatever weight bullet I feed it. Do a google search of the 6.8 barrels, I'm pretty sure two of the better barrel makers will come up at the top of the search.

LWRC Six8 rifles are probably the best factory 6.8 you can buy. A 14.5" with a pinned and welded FH would be my one and done if I went with them. Their proprietary Magpul magazines usually sell for $10 more than a 6.8 mag designed for standard AR-15 lowers. IMO this is a better engineered rifle.
With that being said I have 4 uppers that work on standard lowers. I built them over 10 years ago and the better magazines and LWRC's latest rifles weren't an option then. White Oak Armament sells both complete uppers and barrels in 6.8 if you want to build one custom. Wilson Combat would be my next recommendation. I own a Noveske 13.7" with a pinned and welded brake. A 16" CLE A 18" WOA A 20" Kotonics While not as expensive to run as 6.5 Grendel, I never shoot either caliber for "fun". Lapua brass in 6.5 that gets bent upon ejection makes me since in pain. An old school accuracy load in 6.8 SPC that has shot well in every rifle I own: Remington 9.5 standard large rifle primer Remington brass 28.0 grains of H322 Sierra 115 Match King's Seated @ 2.250". |

You can sell the once fired brass for $50 You can shoot one of the most accurate loads that I have ever used for $7 if you collect brass The 6.5 Grendel you are missing out if you ain’t shooting the Wolf It’s .25 and it shoots 1.25” groups out of my AA 16” and 11” and runs like a raped ape I have only broke one extractor and AA mailed me a free one |

I honestly was annoyed I went a long time not knowing who it was that was banned from being mentioned. I was not in on the early 6.8 craze back in its heyday. I used to see the occasional oblique references and didn’t get the Beetlejuice of it at all. Edit, found it! I was looking at the code of conduct not this sub forum’s own rules. |
