AR15 in 6.8spc
My interest has been peaked in the 6.8spc cartridge and wanted to know if there are any factory rifles, not uppersor conversions, but complete factory ARs chambered in 6.8spc that are affordable (1000ish and under) who are also reliable and solidly built? What are the options? Ruger makes one, it's a 1500ish and I saw Rock River has one for about 1000ish. I don't know anything about these 2 in terms of reliability and performance or what else is out there?? I'm sure theres a nice afforable, solidly buil AR15 in 6.8spc - please educate me!! Thanks!
Check Spikes Tactical, I think they make one.
Is there any difference in the lowers between a 6.8 and 5.56 AR?
No - the idea was to design a cartridge with greater punch downrange but that fits within the existing AR-15 platform, unlike the .308/7.62x51 models which require a longer action and a bigger mag well.
Spikes does in fact build a 6.8
Here is another mfgr. to check out. My son bought a complete 6.8 upper from AR Performance...great specs and very accurate. IMO, he makes some of the best 6.8 AR15's available.
Rock River Arms and Stag Arms also build complete rifles in 6.8 spc.
Rock Rivers rifles are top notch in quality. I bought one in .223 for my son, and we were both very impressed by it.
Are you really sure that you want a gun in 6.8 SPC?
Ammo is far more expensive. Do you reload?
Recoil is heavier. And at close quarters, the .223 is just as effective a manstopper.
Here is a photo of my son's Rock River:
No matter what brand you buy, be sure to get a chrome lined barrel.

The only reason I want 6.8SPC was being it was "different" and has better stopping power. But then I thought, 6.8SPC isn't going to be easy to find in stores. Online, maybe. And it'll easily be more expensive. As far as stopping power, I agree with LanceORYGUN. Up close, the 6.8SPC may have a slight edge but, the .223/5.56NATO round is very effective, especially when using good 75-77gr OTM ammo. I'd say long range is when the 6.8SPC will probably have a clear advantage over the .223/5.56NATO. Besides, I don't hunt, and the chance of me needing my AR in a defense situation is VERY low. So I got some 75Gr TAP for up close and personal stuff if it's ever (probably never) needed. If I really needed to do damage at a distance... I'd look at a .308 or .30-06 round.
If the 6.8SPC is really what you want, go for it! If money was not a factor, I'd have a dedicated 6.8SPC rifle :) But it is, so .223 will have to suffice.
I have considered a 6.8 upper to put on my Stag # 1. For around $700 I can have the complete upper and a couple 5 round mags. This would make a good hog and deer rifle. My 5.56 upper would be my shooter and defense setup with my red dot and the 6.8 with the 3X9 would be for hunting. 6.8 ammo is on the pricey side but if it was just for hunting I could afford a couple boxes for hunting season.Maybe for my birthday.
I've had a couple. It's a great cartridge, but there's not much I can do with it that one of my 5.56's or 7.62's can't handle. The BIG thing for me with the 6.8 cartridge is that I can run it in an 8" gun and still have great performance. As we know, 5.56 and 7.62 both work best in 14.5"+ barrels, perform fine in 12" barrels, but really lose their steam below 10.5". The 6.8 hardly loses anything in the shorter barrels, in comparison.
As for those that make complete rifles, I would not buy from anyone besides Barrett, LWRC, LMT MRP (with 6.8 conversion barrel and bolt), KAC (if they made one), Noveske and BCM & Colt (if they made one). PERSONALLY, I'd stay away from RRA, Bushmaster, etc. You'll pay a little more for these, but you get proper staking, HP and MPI testing, chrome lined & cold hammer forged barrels, etc.
Oh, I'd also stay away from piston guns and stick with DI (unless we're talking less than 9"). There's also no reason not to just buy the upper and run it on one of your current lowers from a 5.56. It won't make any difference and most people I know that end up with a 6.8 just buy the upper.
LWRC PSD 8" 6.8spc
I purchased a Stag Arms 5L (left handed) last year. Love it. Had a few jams in the first 50 rds or so, but no problems since (prob due to lubrication). I do plan on upgrading the stock at some point in the future. In my area, I rarely find ammo on the shelves (Cabela's). I've ordered online thru Midway USA, but recently found another source, JEK Inc. The store front is in my home town, so I typically pick up a few cases when I'm there visiting family/friends. I've fired mine accurately out to 200yds. Currently have a 4x12 Nikon Prostaff mounted. Ammo is typically $1/rd.
If you don't have a specific application in mind, I guess it's really up to preference. If you're looking for a bullet hose, probably not the best choice.
I left out that if were to ever buy another 6.8, I'd probably go for a precision 16" upper. If you were to do it that way, ammo is much closer in price to the precision 5.56 stuff. Don't get me wrong, I rattle off some rounds doing drills with the 6.8, but I prefer the 5.56 for that for numerous reasons. So, you might want to look at doing it that way… BUT AGAIN, I still can't see doing that over a Mk 18 Mod 1 5.56 or a M110/SR-25 or even the LMT MWS in 7.62. Just thinking out loud here, sorry. I've just gone through so many guns in these platforms and even when I buy 6.8's, I always wonder why I didn't put it towards something else.
I'd strongly suggest starting out with just an upper. If you like it that much, buy another lower and make a dedicated 6.8. There is NO disadvantage in doing this over buying a complete rifle all at once, nothing is fitted between the lower and upper.. Now, if you DO NOT currently own an AR you can do this with, I'd absolutely say skip the 6.8 and go with a nice 5.56..
You might want to take a look at the 6.5 Grendel. I'd also suggest going over to 68forums. Remember, you want the scpII chamber and a minimum of 1:10 twist.
I'm thinking of going with the Stag 6.8 upper to go with my Stag lower. Yeah I know I should maybe go with at least a 16" barrel but I really like M-4's and for deer and hog this will be enough barrel length.
