Home Forums Hunting & Shooting AR and Tactical Rifles 6.8 SPC upper

from my understanding you can use the 20 and 30 rnd mags, but you have to "cut" the spring and put a new follower in it. I also think you cannot use the aluminimunmm mags cause they will bulge. I don't know how true this is or have first hand experience.

Here's a 6.8 on the cheap

and here's one that comes with better recommendations

Neither are much costlier than a decent .223 upper from my understanding.

I've revised my consideration of the 25 WSSM upper to that of the 243 WSSM. The 25 requires seating the bullets deeper and precludes factory ammo. The 243 wssm does not have that limitation. I am a handloader but still believe that aspect makes the 243 WSSM more attractive. Also the builder recommends the 243 for my applications over the 25 and he has much more experience with both.

Mr. RickyD,
And what applications do you have in mind, if you would not mind my asking?
Best Wishes

RickyD,
I was unaware that the WSM OR WSSM's were even an option. Won't the pressure/recoil beat the AR to death using such "hopped up" ammo? I agree, the 243 WSSM would be a doosey for an all round hunting gun, especially on an AR frame. I'm just very wary of the wear and tare on a frame meant to only handle the recoil of the little .223!!! <img src="/ubbthreads/images/graemlins/shocked.gif" alt="" />

I'd say he wants to hit someting far away really hard,,,,, <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />

Mr. Windwalker,
Of course I don't mind. Primarily coyotes and deer. Pigs on occasion. Also punching paper. The 6.8 would do those duties too but it would not be as flat of a shooter as a good 6mm bullet. Anyway, I just like the idea of a AR with some muscle. Guess that's why we have 50 Beowulfs. I'll admit I'm re-considering the 6.8 too. Those uppers cost half of what the 243 WSSM's do.

ought6,
Only the WSSM's are available on an AR15 frame. The WSM's can be had on a AR10 frame. There are several other interesing cartridges that can be chambered for an AR15 upper such as the 6.5 Grendel and the 50 Beowulf and of course the 6.8. As far as beating the gun to death, I'm sure you could be right but I think the right builders know how to fit the appropriate components and gas system so it will work reliably for a reasonable round duration. Of course I would not consider one to have the longevity of a .223 but neither would I shoot one as much as a .223. In the final analysis, it may be just another symptom to a disease I am unwilling to cure just yet. <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />

My apologies for any hijacking of the thread.

na, I don't care

What cartridge is the Grendle basedon?

The grendel is a slightly higher capacity 6.5PPC

same case head as the 7.62X39 but not a sharply tapered case like the 7.62

I want a grendel AR for hunting,,,,,

Yep! The Grendel looks like a good one too! Here's some info on it from it's creator: http://www.alexanderarms.com/website/id22.html

Ricky

Its funny that the actual creator is not mentioned and is not Bill Alexander...... But its still a super round for what its intended for.

Its a shame we can't buy a barrel only a bit cheaper though....

Jeff

My bad, then. Thanks for pointing that out, Jeff. I thought Alexander was the guy who brought the 6.5 Grendel out. It looks like they are about the only game in town offering uppers. They are pricey. So are the WSSM's. Economics make the 6.8 look better all the time. <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />

could you not have a grendel barrel made by someone else????

Arne B first developed the round didn't he???? he started off with a 6.5PPC

"could you not have a grendel barrel made by someone else????"

Maybe. I haven't looked for a couple months but none of the barrel sites I was checking showed they chambered for that caliber. I'm sure someone will begin chambering for it soon if they are not already. With calibers like that in the AR I would want the right builder putting it together, though.

Yes, anyone can fit and chamber a 6.5 barrel. You just have to have a 150+ buck reamer. And have AR knowledge. I'd trust John Holliger to one in a heartbeat. BUT a custom barrel isn't going to be cheap. Though you might get a better barrel than the Walthers they are using.

AND there may be a copyright on the design IE you'd have to get a 6.5 PPC instead.....Not at all sure on that one.

I know Arne did all the leg work and had guns built by Medesha first. Then took it to Bill. I fixed the mags on the Medesha guns to make them feed and test fired it at 600 yards. It was an unbelievable round. Fired a perfect score without correcting for wind at all. In conditions that should have netted something like a 196-197....

FWIW I do know that John Holliger is doing tubes in 6.8 necked to 6mm already.

Jeff

i tried for the 6.5 grendel and you have to buy the uppers. no one will cut a grendel reamer for you <img src="/ubbthreads/images/graemlins/confused.gif" alt="" />

the 6.8 necked up and down sounds like fun though.....

woofer

If you give specs for a 6ppc necked up to 6.5mm they'll cut a reamer. Just dont' ask for the Grendel.... (I believe IIRC there was no other major difference as I referred to the round as 6.5ppc for a long time till I was told different)

Jeff

To add- just went to JGS- they list a 6.5ppc reamer!

I just read somewhere that the 6.8 SPC is probably going to be obsolete in a few years. I disagree if this indeed becomes the military standard.

Do y'all think there is any chance this is a passing fad?

E4E will disagree but the military folks I have talked with all think the 6.8 is a joke. Most are Spec Op type and say the 223 with 77s is just fine and if you need more than that either learn to shoot or pickup an M14 or bolt gun.(both still in inventory as our state team civilian rifle team trained a bunch of infantry in the use of the M14 a year or two back)

I just don't care that much for the round. I like the Grendel but then again I'm biased as I shot it in its infancy for some testing and it was super as a 6.5PPC round.

The only real way to tell is let time pass though!!

It would take a big revamp to switch calibers and weapons but it was done not that long ago to go to a 9mm(which the folks I talk to say is about worthless compared to the 45)

And of course 6.8 is not a nato round so compatability becomes an issue(probably a big reason in adopting the beretta anyway)

Just my take on things.

Jeff
