That is a sweet looking rig but not sure if I will invest in one. It will surely help the 6.8 gain even more traction though. Now if ATK will get that ammo out so we can buy it!!!

So what is the hype on this LWRC rig? Did it say when it will be available?

Re: LWRC releases more infor on their Six8(6.8spc)

The biggest difference is the enlarged mag well and it uses Pmags. The 6.8 round runs best at 2.9-2.3" OAL so the LWRC is said to handle 2.32".

I don't care much for either, I'm just glad it will open more doors for the 6.8 and get cheaper ammo out. We have the cheap mags worked out with the new CPDs, only thing needed now is cheaper ammo...

No ETA that I know of...

Are the PMAGs 6.8 specific? or modified 5.56 mags with a change in follower? How many will they hold? 28? 30?

Re: LWRC releases more infor on their Six8(6.8spc)

6.8 specific and holds 30rds, hence the enlarged mag well.

It's a good looking rifle. Anything to increase the popularity of 6.8 and hopefully bring down the price of ammo is a good thing.

Re: LWRC releases more infor on their Six8(6.8spc)

If they were going to have to completely modify the lower to take larger, wider mags for the 6.8. I wonder if they would consider making an entirely new weapon system to bridge the gap between 5.56x45 and 7.62x51 and run with the 7x46mm UIAC/Murray?

It's not entirely new, just modified a bit. I am a big 7X47 fan; however, it appears the folks involved wanted to keep the same size, weight, etc as a AR15 but maximize ballistics out of an 8.5" bbl. The 6.8 does this well, the 7X46 does not.

Looks like a sweet little package and will undoubtedly be LWRC hella-tough, but I'm not sure what a 6.8 offers that a 7.62 SBR doesn't.

Wonder if anyone will build a 7x46? I just can't get my head in the 300blk, or 6.8. I would be willing to try a middle of the road 14.5-16 inch gun that truly fits between the 5.56 and the 7.62.

Not sure if this will help the 6.8 cause, a 6.8 Specific rifle comprised of an upper and lower thats not interchangeable with standard ar parts, I suppose it will have its niche market. The link provided is a well written article by Major Thomas P. Ehrhart with regards to Increasing Small Arms Lethality in Afghanistan, good discussion on the 5.56, 6.8SPC, 6.5 Grendel and the 7x46mm.

The 6.8 is around 80% the power of a .308. I haven't ran a .308 SBR but I'm sure the blast and recoil are not nice, not to mention the extra weight of the AR10 platform. The 6.8 just offers the most out of a AR15, however, I don't see it as a .308 replacement...

That is a good point and one I have thought about. The changes will have to be very good for me to leave my mil spec AR15 receivers for the Six8. The 6.8 has been much improved since we have left the shotty SAMMI spec and went to the SPCII/ARP type chambers. Who knows what else is open for improvement...

mjh - excellent study, I'm about 1/3 of the way through it. Thanks for posting this.

I think the last 20% costs you 40% more powder. The blast is a LOT less.

Re: LWRC releases more infor on their Six8(6.8spc)

346ci, with regards to LWRC I am not knocking the companys improvements to the their 6.8 rifle, designing the rifle around the cartridge is an excelent idea and their changes show this, it should make the very most of this chambering. Reading a recent article by Cris Murray he mentiones how changes to the magazine well and magazine could have occured when the M16A2 came out but those in charge failed to take advantage of this opportunity. Jonthomps, I thought it was well written, I thnk the major point that really jumps out at me is how dependent the country is on the Lake City Plant for samll arms ammuntion and how even if a different cartridge was approved how would the changes be implemented.

Huh, makes sense. I had a Noveske 6.8 Recon upper w/ a Surefire brake. The positive was it was nuts accurate (3/4 MOA or a little better) and the recoil was similar to a 5.56. The bad was that I thought the fouling was wayyy excessive compared to a 5.56 DI gun so I sold it. Maybe I was just bein' a little girl.

Totally agree. There are lots of "better" products out there. Finding a better product is sometimes not the problem. The problem is most often logistical, or as you put it, "how would the changes be implemented?"

I'm not knocking them either, they make great products for sure. Longer COAL loading has been needed since 04 and we were very limited on mags for a while that could run a 2.9-2.3" COAL. PRIs that were/are $40 a pop also. Chad at CPD is getting his new mags out that allow 2.3" loads and they are cheap to boot. Between that, LWRC and the ATK ammo deal, the 6.8 is really smokin'. I'd like to see some cheaper ammo before 2013 but I can wait as reloading keeps me going pretty good.
