Re-Barreling in 6.8 spc

I'm leaning towards this. DPMS

I've had good results with DPMS and cant beat the price.


2 questions
Has ne one used this barrel?
What kind of bullet weights should I be going with for a 1-11 twist?

You'll be good up to and including 130gr, over 130gr may be hit or miss depending on projectile design.

I have no experience with the DPMS 6.8, I use Bison Armory barrels.

1:11, or 1:12 with a SPEC II chamber is the preferred way to play 6.8


avoid 1:10 and "SAAMI SPEC" at all costs


no clue about DPMS...I can't seem to open your link.


I have a White Oak middy that is amazing.

Your link is dead but I found the one you are looking at. Might want to give Midway or DPMS a call to see if it is a SPC chamber, you will want the SPCII chamber. They have the twist right though. The Wilson barrels are not labeled as SPCII either but I know they are. Looks like Midway needs to add some more detail to their 6.8 barrels...

No need for a 20" 6.8 unless you want a long rig, the 6.8 does fine with a 16", just pick a good barrel.

I was planing on something for longer ranges 500-600yds (is that asking to much)

Contact H at AR15 Performance, Ben at Bison Armory or Bill at Wilson Combat. White Oak Armory would be a good choice also. Have any of those guys hook you up with one of their 18" barrels and you will be fine. 500-600yds is pushing the 6.8 but would be work for target shooting, you would not want to hunt at those distances.

For those distances, the 6.5/.264 would be a little better but still not worthy of taking deer sized game.

I second that!

DPMS has SPC II & 1:11. But, a 6 groove twist.

BHW makes some good pipes too. There is really a lot of good choices out there, I usually list the ones I know will be great, even if I do leave a few out.

I think BHW makes a 20" also

As stated before, stick with ARP, Bison or Wilson. Better options that are all well tested and proven good shooters. As for the 500-600 shooting, yeah, it will shoot that far, but for target shooting only and target shooting at that distance with a 68 just seems like a waste of money. The rounds are expensive, unless you reload. Just stay with 5.56 if you want to shoot paper that far. Just my opinion though.

How about Ar-Stoner

(I love Midway as close to instant gratification as you can get)

If you must go with a Midway choice, go with a Wilson. Their 18" Recon is on sale @ $240, only one left though. The Noveske would be a nice one but the price kills it for me, it won't shoot any better than the Wilson.

My 16" Noveske Recon will shoot five shot sub-moa groups at 300 yards with my 100gr Nosler Accubond reloads, as long as I do my part.

do you have any idea what you are talking about? I don't want to sound rude but the avoid 1:10 at all costs is incredibly ignorant. LWRC makes a sub moa 1:10 that handles everything hot you can put through it. There are other 1:10s that are absolutely fine.

chamber, rifling, throat, comp of barrel are far more important.

Pass on the DPMS looking at the specs quoted:

Technical Information:
20" Heavy Contour 4140 Chrome-Moly Steel
Chambered in 6.8 SPC
6 Grooves, RH Twist, Button Rifled 1 in 11" Twist
Manganese Phosphated Black Finish
NOTE: DPMS 6.8mm SPC barrels are threaded 1/2"x28, the standard thread pitch for 223 Remington caliber muzzle brakes and flash hiders. Using a 223 Remington caliber muzzle device on a 6.8mm SPC barrel could be dangerous and should NOT be attempted. Please be careful to select a muzzle device of the correct caliber for use with this barrel.

Stoner barrel+bolt is ok, but I'd still shop around (ARP, Bison, BHW, etc., etc.) before buying:

Technical Information:
Features an SPC II chamber and 5r rifling. As a result of the configuration of the SPC II chamber, hotter loads are held to sustainable pressures yielding more velocity without being compromised by higher pressures
Gas Tube Length: Rifle Length
Gas Block Diameter: 0.750"
5/8"-24 threaded muzzle
Muzzle Thread Engagement Length: 0.620" with a tolerance of .005"
M4 Feed Ramps: No
Not relieved for gas block cross pins

Personally, I went ARP and haven't been disappointed. YMMV

He said 10 twist AND SAAMI––meaning the SAAMI chamber combined with a 10 twist barrel.

my bad....I apologize.....I read it too quickly and am wrong.....very sorry drek

Yes Sir, I know exactly what I'm talking about

Research it yourself, call SSA and ask them if you can shoot there
hotter "combat loads or tactical " through a 1:10 SAAMI.

They are loaded hotter and will show signs of pressure...swipes....popped primers,etc..
If you try to shoot them thru a 1:10 SAAMI

Join the 6.8 forum and read up on it

Thanks I didn't even notice the muzzle threading issue I won't be going with the DPMS

I will keep my options open I was just trying not to spend too much, but the old saying goes you get what you pay for[8D

Given your desire to keep costs down, I would roll with a Bison 16" Recon (ARP is out of stock) and call it a day.

I've owned the WOA barrel and it was very good, though a little heavy, which is why I sold it. I've stuck with Noveske since then and have been very happy, though I think my next purchase will be a Ranier UM 18". I wouldn't worry about the 1in10 twist as long as the chamber specs are good.

Here is another option for just a few dollars more that is likely an order of magnitude better than the DPMS you were looking at. Click here.

I have a DPMS with a SAMMI chamber and 1/10 twist. I got it when the 6.8's first started coming out. (Note, I do have a JP match trigger and the barrel was Cryo'd) I can hit bowling pins 50% of my shots at the berm at 565yrd with a MK4 1.5x5 SPR scope and cheap Remington or Hornady ammo(this ammo is know as about the worst 6.8 out there). I plan on getting a Bison or WOA barrel when I get around to it. I have not shot the rifle in about 3 yrs since I got a RRA NM A4. So in short, yes with the ability to use the hot loads in the SpecII chamber a 1/11 will work fine for you. Im probably going to go with an 18in barrel though.
