Steve, I've been so close to buying a RRA 6.8 upper, and your upcoming chrome lined option is getting closer to the specs I'm looking for. I understand that Wilson has 1:11 twist barrels for the 6.8. This is just about the perfect set up to go along with your SPC II chambers. How about getting some of these barrels in your uppers? This would be a home run for RRA to have 6.8 rifles/uppers with SPC II chambers and 1:11 twist. Thanks. |

I am glad that you guys are keeping an open mind about it. All of the custom uppers have moved to 1:11 or even 1:12 to run the Silver State Armory Combat Loads which are hot in a 1:10. With a 1:11 and the SPCII chamber I think you would be offering a more reasonably priced alternative to the custom uppers and set you apart (even more) from other brand's. If my 1:10 shoots as good as I think it will, I will get another one! (my next one will definitely be 1:11) Just my 2cents. :) |

Steve, I really appreciate being able to talk to you, the company, direct so to speak. I am a fan of Rock River Arms and your midlength chrome lined 5.56's are my personal favorites. As you stated, I agree RRA's are very accurate rifles, however the 1:11 twist is not to improve the already fine accuracy from your products. The 1:11 twist gives the 6.8 shooter the ability to shoot some of the more powerful loads and bullets being manufactured for the 6.8. Having a 1:10 twist even with the SPC II chamber can leave some performance on the table, that's all. The 1:11 seems to be a better all around choice. I understand Wilson has the barrels available. Lothar Walthar also has made a move to offer this type of barrel. How about being the leader of the pack with RRA's quality and value combined with a 6.8 1:11 SPC II chamber? I see a demand for this product now that many enthusiasts are aware of recent load developments for the 6.8. The 6.8 is still developing. We need a production manufacturer to offer updated barrels. Could that be RRA? |

Thanks Steve. I appreciate the consideration. You're in the gun business obviously so I'm sure you guys know where to go for 6.8 information. Silver State Armory and others over at 68forums.com have shared lots of information on the 6.8. Check out some of the forum postings there if you haven't already, and you'll see that the 1:11 4 groove rifling and even the 1:12 rifling has performance potential for the ammo break throughs in this developing round without a potential for pressure problems. My money is where my mouth is. Make me a RRA midlength 1:11 twist, SPC II chamber, preferably chrome lined, along with RRA's reasonable pricing. I'll buy one right away. Thanks again for your consideration. |

The 1:11 Wilson barrels are all also getting sub moa with SSA ammo and .5 moa with a SSA load or two and hand loads. You are not going to loose accuracy by making the switch and the 1:11 is a stocked item at Wilson. We are getting sub 1/2 moa with 1:12 barrels and properly stabilize bullets as long and large as can be sued in a AR magazine well. Take a look at a twist calculator and you will see how over kill the 1:10 twist is for the 6.8. Cris Murray the creator of this round wanted to use a 1:12 and still thinks it to be ideal. The only reason the 1:10 was used was it was all that was available in a .270 bore that could be had quickly. Wat really matter to a business also is that it will help sales even if they are doing very well now. I do give you guys big props for having the forethought top use the SPCII or long leade chamber. You uppers are considered a best buy and the only thing that has held some back is the twist as hit does happen the performance with this cartidge in an AR. The 1:11s are getting 100 fps+ over the 1:10 with the same if not better accuracy. They can handle a significantly higher powder charge without pressure issues. Also this would also increase the longevity of your guns action parts as it will slow down bolt speed and help prevent premature bolt unlocking whihc will cause broken extractors etc.. Changing to a 1:11 barrels would allow many to make your upper one of the top recommended ones. You already have the best price point. Make that change and there is hardly a down side. There is a significant amount of data to support this. If you would like PM me here or come over to http://www.68forums.com and e can provide you with plenty of supporting data. Again I think other then that one thing you have a great offering and you have given shooter an affordable option that doesn't sacrifice quality. Make that one change which should be a zero increase of material cost and you will have a top end performer at the best price point in a 6.8. Tim_W |
Ya what he said. bring that shit on and make it in a govt profile. 223 too small 308 too big. 6.8 rules. |
| I have 2 5.56 RRA uppers and I am very happy with them. I also have 2 6.8 SPC uppers that are not RRA. They probably would have been RRA's but, I wanted the 1:11 twist barrels and SPCII chamber which you did not have available. I hope that your company looks into providing 1:11 or even 1:12 twist barrels as I am a big fan of RRA AR's. The 6.8 is not a large cartridge and it needs all the help it can get in the velocity department. The 1:11 and 1:12 twists along with SPCII chamber help provide this velocity with handloads and the hotter factory combat loads.hanksBill |

I have a lower receiver I am dead set on putting a RRA 6.8 midlength 16" upper on. However, I cannot justify the purchase if the 6.8 won't shoot the loads I want to use safely. The other brands are too custom and way too expensive for my blood. Uppers with no BCGs or flash hiders costing $525 or more. That's absurd. I'm waiting to click "submit" as soon as RRA posts a 1:11" twist 6.8 midlength upper. Credit card is in my holster and at the ready. Also, it would be advantageous to order a 6.8 kit less the stripped lower just like you can with the 5.56 kits. RRA quality throughout the entire gun. Future owner of: RRA 16" 6.8 SPC midlength w/ 1:11" twist and the new chamber NO OTHER BRAND WILL APPEASE ME. Just my buck o' five. Brent |

+1 for a change to 1:11 twist on the RRA 6.8 SPC barrels. I'll be in the market soon for a 6.8 upper for my new 5.56 RRA A4. I am only considering 1:11 twist uppers after learning about the benefits on them. There is no reason to have a 1:10 on a 6.8 SPC. No one is going to shoot 150's out of them. thanks kindly, dxr |

Absoiutely offer 1:11 twist barrels with the SPCII chamber!!! You'll have guys crawling over rocks to buy RRA 6.8 uppers and rifles with 1:11 barrels. If Wilson stocks 1:11 twist barrels, it's a no brainer. I have never considered RRA for my 6.8 builds, but I definitely wiil if the barrels change to 1:11. |
Steve and RRAs Production Team Members, The quality of the RRA guns are top notch and only building on a truly solid foundation. That said, the ongoing development and sharply increasing interest in the 6.8 SPC can only boost that reputation. Providing consumers the means to make the most out of that popular round will only provide more positive responses. By producing and offering the 6.8 SPC barrels with the Spec II chambers and a 1:11 twist rate would allow for the consumer to use the higher velocity ammunition offered by SSA at this time. Hopefully, other ammunition manufacturers will follow suit and offer top shelf loads for this wonderful hunting/PD cartridge. I too would like to offer my request for your company to be taking the reins and showing others how progressive and responsive to consumer inquiries RRAs can really be. Thank you for your time and sincerity in this endeavor, KellyR |

Yep I'd really like to see RRA go with the 1/11" twist four groove route. Their quality/price ratio is a winner. Now if they'd only get the barrel specs dialed in and be very public that the SSA "combat" loads were good to go with the new barrel, I'd snap one up in a heartbeat. I'd like to see Mfgs. settle on the hotter ammo as the standard. |
| You can add one more RRA fan who wants the 6.8 offered in 1:11 twist. My 5.56 rifle is RRA-everything except the actual lower receiver. When I made the decision to get 6.8, the first place I looked is RRA. The reason I didn't get the RRA upper in 6.8 is because of the research I've been finding on which twist is better. I went with a more expensive upper because it has the SPC II chamber and chrome lined bore in 1:11 twist. You were missing that one thing that kept me from buying your upper. |
This guy is right.. I can put it a lot simpler, as follows : come on RRA get off your butts and order 500 barrels like this whip up a special edition upper or complete rifle and we will buy them. It that simple. Just do it already!!!!!!! |
Know all about the drive for slower twists and am a member at 68forums. |
So you're a third of the way there -- great! Now just add 4-groove rifling (the only SAAMI spec that is accurate) and 1:11 or 1:12 and you'll have one heck of a package. |
|
Actually, it's already a heqq of a package with what we're producing now. This thread is becoming kinda redundant with all of the "+1"s. etc....how about we give it a rest for a little while as we discuss it here. I promise that I'll provide any updates as I get any additional info. Thanks. Steve/RRA |

Alright ARFCOM. Not to start any arguments but it's been a month. I don't want this 1x11" thread dying haha :) So forgive me for being an arse: This post is a bump and to remind the world 1x11" is in demand. I want to see a 1x11", four groove, improved chamber, midlength 16" A2 upper from RRA. I check the website daily in hopes of clicking submit. Ko-tonics is about the only provider of this setup and I personally can't stand how they are doing business. The upper they sell is incomplete. Doesn't even include a charging handle. These kind of nickle and dime'ing policies are why so many want to see RRA produce the 1x11" We know we'll get a good product that's COMPLETE for a good price. This is just a bump. I know RRA is aware of 1x11" demand but it's been a month and this is a bump to keep awareness of the demand in sight. Sue/flame me if you want, just so long as I can purchase an RRA 6.8 upper with 1x11" (even as a custom order for $100 more than standard, whatever it takes) Brent |
You are right how about a govt profile 16 inch while they are at it. And a SBR in 6.8 I would buy both. I have their 16 inch middie but it is a little heavy in the HBAR config. |

Investigating different aspects of it. We (or any manufcaturer) doesn't just call Wilson (or any barrel maker)and say "Hey...make us some 1:11 6.8s" and get them within a few days. We have to do drawings, specify multiple parameters, tolerances, get quotes, test first articles, etc...then fit them into an already full barrel production schedule. I have ownership support for it at this point, but alot more has to be done before the project can go a whole lot further forward. It's a couple month process once the commitment is made to making them (and all of the above is accomplished) before anything tangible will be seen. Steve/RRA |

Steve I thought you might like to know this is being discussed over on 68forums.com You need to be a member to post (its free but to prevent spam its set up this way) here is the link to the RRA 1:11 discussion. www.68forums.com/viewtopic.php?f=1&t=2859 |
I am really impressed -- You can put me down for another 6.8 upper when the new ones come out! |
|
We're still looking at the 1:11 and what it brings to the table...beyond just changing the rate of twist on the existing barrels. That said, we're not experiencing any problems with accuracy, problems with the so-called combat loads, etc...with our current 1:10 with the SPC-II chamber... Steve/RRA |
I understand that. Do keep in mind that there is a modest velocity increase with the slower twist, as well. In this magnum-crazed world, every 'fps' is valuable to quite a number of people simply for the increased point blank range. I've been tinkering with the 6.8 awhile and I want to relate a bit of my story with you. My choice whitetail deer bullet has been narrowed down to the Hornady 110gr VMAX. I know many will say "that's a varmint bullet!" but I've had excellent results with its accuracy and performance when delivered into the boiler room on whitetails. Absolutely explosive and liquefies all of the heart and lungs... but only between the ranges of 75 yards and 150 yards does it have that "bolt of lightning" effect. If less than 75 yards, my bullet will explode prematurely, and I will have needed to apply a neck shot instead. That's understandable, and a neck shot is super easy at 75 yards or less. If more than 150 yards, I'll have the bullet exploding on the offside of the deer and while leaving a huge exit wound, not enough organ damage will be done and the deer will run awhile before expiring. I don't like wounding deer, or tracking them and I DO like bullets graced with the qualities of a bolt of lightning. Anything at all that will increase the effective distance of this load, I will buy. The 1-11" 4 groove is documented to give 50-70fps increase, and I think that'll be just the ticket to increase my "effective VMAX on whitetail" range. Anyway, I apologize for using 266 words to say what could have been said in nine. "I am still holding out for the 1-11" RRA!"

I am also a RRA (have 3 in 223 !!) fan and owner and I am also holding out for the 1x11 twist in the spc chamber  Faster twist = heavy bullets+increased velocity=better stopping power which is the reason to get the 6.8  Meantime I will wait for RRA and save and wait and save etc  Thanks for listening to ARcom folks,we spend a lot of money on our AR's and have big mouths  John |
