This is a reply I received when inquiring about a 6.8 bbl for a Savage 110 : ----------------------------------------------------------------------------------- Ray, good morning The 4 Savage factory contours that we copy are set up with the standard 1.060 hub diameter so that you can use the factory barrel nut for fit and headspace. Yes they are fully chambered and in 4140 chrome moly they are in the "white", bluing is additional, and in 416 stainless they have a polished finish.I will breakdown the costs: bbl- $135.00 4140 chrome moly steel threaded and fully chambered ready to finish and install in the "white" bluing- $30.00 either a matte or polished blue finish for a barrel only bbl- $200.00 416 stainless steel threaded and chambered, polished finish bead blast- $25.00 gives stainless steel a dull non-reflective finish, stainless barrel only shipping- $12.00 Turnaround time is approx. 8 weeks on the barrel order and all barrel orders are billed up front. All you would need to do is send in your order with the barrel contour needed, caliber, length, material, finish and shipping information along with the form of payment. Unfortunately we do not offer the 6.8 SPC caliber. I hope this answers your questions. Thanks Chris ----------------------------------------------------------------------------------- Maybe they don't offer the 6.8 because they can't control the bolt head modification required ?? PacNor has it listed on their site. rj |

Must be a special thing they do for Model 1 Sales ?
. . . although LW has 6.8 barrels from them ? Technically ERShaw's OEM division (handles larger production) is Small Arms MFG, maybe ERShaw doesn't do it for one-off's but their OEM will do it for larger orders . . ? I am just guessing |

God Damn- I wasted $400 on a .41AE. Freaken "Round of the future." Now, I sit on the sidelines and wait for 'caliber wars' to work themselves out. |

L-W, I would like an answer to this as well. And could you include throat, bore and groove diameters? Thank you for your info & ballistics input. Again, thanx, Dave S |

Sorry, busy. To clarify, these are the SAAMI specs with the 0.059" throat - we haven't tried the other yet and they are Small Arms Manufacturing barrels.

dude I coulda told you that... Just cutting a chamber on a shaw you can see that it's nto near the same quality metal as the better known ones. |
|

My edited post was for chrome-lined 6.8mm SPC E.R.Shaw barrels. And even with my complaint of flattened primers at only 25gr of H322 the barrel shot in the .3XX" @ 100yds. BTW, anyone with credentials want to tell Snaps where... ooooooooh it's a Colt gets their barrels from, hhmmmmm? Dave S |

|
i'd bet it's not shaw, becasue when we did the factory tour they were telling us they didn't do chrome lined...
Either way, I don't really care, if somebody else is going all hte work for me I'm not going to worry about it. But cutting them nad then having to handlap them isn't something i'm going to do if I can avoid it . |
|
Don't bet too much, you would lose it. Shaw has certainly produced a bunch of colt barrels from what I have heard. You are correct that they don't do the chrome lining. The barrels get SENT OUT to a chrome plater before Colt final assembles the barrels with a FSB, handguard cap, barrel nut and barrel extension. |
|
|
I'll try again.
Does DPMS make their own barrels? (The web site says NOT chrome lined) Any reported problems with their 6.8? |
|
That's what I'm talking about!!! Thanks for the info. Stephen |
|
|
Break it down for us:
if we want to purchase a 6.8mm SPC barrel that is chrome-lined and properly to spec, what are our options? I plan to add a SPC upper to my collection this spring sometime. |
|
Let me know when you find out... |
|

+1 No barrel manufacturer does chrome lining in-house. (at least I have never heard of one) Shaw (or I should say; specifically Small Arms MFG) produces what I would call a contoured blank. It is cut to length, contoured, with bore and chamber. It would then need to be chrome lined (if applicable), phosphated finish (parkerized), gas ports install, front sight installed, etc. Maybe some of this confusion comes from the fact that Shaw has 2 divisions, one for precision platforms for one offs and an OEM for volume orders (button rifled). Alot of barrel manufacturers have two divisions; Krieger, Mike Rock (Rock Creek), etc. They will have different features offered depending on the type of order. |

What's the big deal with chrome plating for a semi auto weapon ?? At this point in time I am feeling very relieved that I ordered mine plain.

I just got off the phone with DPMS.
They are a local Minnesota company. They told me they make their own barrels. I usually don't buy their products, but they do offer their 6.8 barrel w/chrome as option. These are the current players that I know - Barrett - Feddersen ( never seen a Barrett upper yet) Bravo Company - Shaw DPMS - Eagle Firearms -Shaw Jarvis - Leitner-Wise - Shaw Model 1 Sales - Shaw MSTN - PRI - Any others, please post for all to see. |

Not a big deal on civilian owned rifles (semi or full auto). While chrome lining does have a variety of advantages, the biggest is probably is its resistance to the elements of exposure to the environment. Something that is important to the military. |
|

Wait, you mean you don't have an M16 fire control group in YOUR AR-15? I thought everyone did... That's why they need the chrome lining. Maybe some people equate chrome lining to a reduced requirement to clean and take care of it. At least the chrome protects the bore from their lack of maintainance. Personally, I like the accuracy and precision I get with a plain bore, but then I know how to take care of one. No chrome for me... The arfcom commandos that are lucky to shoot 500 rounds a year, Yeah, they need the chrome... |
|
|
No, just genuine M16 upper [ AF ] . Even it's an oldie and just has the chrome chamber. If I can't clean it right when I get home it gets a heavily oil soaked patch run up the chamber and bore to give the bbl ext and the rest of the non-chrome bits some corrosion protection until I get a round tuit. rj |

The 6.8SPC velocities don't warrant a C/L barrel for wear. Its not like a 5.56MM @ 3000+ ft/s at the muzzle. I have mine built with SS match barrels. We will see what LMT has in store during the SS for the MRP. |
|
|
I've heard the rumors about LMT and SPC. I really hope they release regular SPC barrels as well and not just for their monolithic rail platform.

Double Star / J&T Distributing offers 6.8 uppers. www.jtdistributing.com/ |

I am an LMT dealer and I inquire about the 6.8 SPC a few times a year. The answer has always been the same: "When we can get 100,000 rounds of ammo for endurance testing, then we will move forward with out 6.8 program" If they are serious, that should be happening in the next few months as ammo is becoming much more available now... Time will tell. |
|
|
A question from the same church but different pew... Has any tier of manufacturer performed/published any throat erosion testing on the 6.8? Particularly, I was wondering "x" round count resulting in "y" degredation of accuracy in CM and SS barrels. |

The L85A1 is not a good gun. Even airsoft players wont use it
|
|
Got the AMEETEC lower in a few days ago. Will post a pic later. It has the original rollmark , that means "small" for those in Rio Linda.

If I want a deadly CQB cartridge I will get 77gr 5.56. If I want a thousand yard plus AR15 I will use Grendal. There isnt any room for 6.8. The industry and consumers know this so the support isnt strong enough to get it off the ground.
Notice 2006 SHOT had grendal everywhere |
|
WTH is going on? Are you gonna us to death with this? I can't stand it any longer! IT'S SPELLED GRENDEL! NOT GRENDAL! |
|
|
I email STAG Arms about a 6.8 spc there reply:
We should have a new 6.8 in the next few months. Sales |
|
This is GREAT news! I could never understand why they make 6.8 marked lowers and complete bolts, but no barrelled upper. It was bound to happen. I cannot wait another 2 months though!!! I am currently looking at the CMMG mid-length 16" upper. Any comments on CMMG? I know nothing about them. |
