Thinking about getting a 6.8 upper in the near future. What are some real good ones and what is cost? Upper can be mounted on a regular .223 lower correct, just want to be sure.

Thanks

Oh, and if possible, a good manufacturer that offers a true left handed model if possible. Tis not a deal breaker but it would be nice.

Edit: I have looked and noticed that stag makes an upper 6.8 in lefty ;) Kinda like my .223 lefty from stag

still open to other suggestions though

there's a recent thread on a new Stag Model 7 coming out in mid-december. 6.8 varmint, 20.77" barrel 1/11 twist. Dunno if they'll sell a separate upper...but there's an article too, check it out.

I'd go with the Stag. What more could you ask for... http://riflegear.com/p-138-stag-arms-model-5hl-68mm-left-handed.aspx

My lefty Stag 6.8 SPC M4gery is a winner, and since I reload for it (Dillon XL 650 with Redding 6.8 SPC die set) it doesn't cost me much more to shoot than my 5.56/.223 AR's.

If you're a lefty shooter and want a 6.8 SPC upper/rifle, Stag is your best bet, IMHO.

OP asked about cost . . . assuming that's the cost of the upper not the cost of the ammo, the Stag 6.8 SPC upper is only slightly more that Stag's 5.56 uppers.

Not sure I'd want the Model 7, though, since 6.8 SPC is essentialy a short range round. If you want to go long range, I'd either go with the Model 6L Varmint, or go all the way to an AR-10 clone in .308 Win. Again, just MHO. :)

Thank you much. When we say it is a short range round, what is the maximum effective range? where does it max out? I am happy if it is still at it's best at 500 yards

Randall (AR-15 Barrels) is the guy to answer this one, but FWIW, my walking around sense is that 6.8 SPC is effective to about 300 yards or so, and after that it's not really your best choice. It may get to 500 yards without having to lob it like a mortar shell, but I don't think it's got a lot of energy left when it gets there. I think of it as a short range puncher, not a long range reach-out-and-touch-someone round. Maybe if you put it in a 24" barrel you'd do better? For my money, I look to the .308 to get out there and do the real work at 600-1000 yards. The "SPC" really says it all: "Special Purpose Cartridge," and that special purpose is NOT usage in the 500-600 yard range, IIRC. It's for short range (0-300 yards) work and getting through cover to get to the BG that the 5.56 round isn't able to do.

Yeah, I think I might take a look at .308. though if I go for that chambering, I'm likely to just get a Remington 700.

I know that I may get yelled at for mentioning this, but if you want a long range AR, an AR-15 in 6.5mm Grendel is probably a better choice than an AR-15 in 6.8 SPC or AR-10 in .308. With factory loaded cartridges that use 123gr. bullets, you'll still be supersonic out to 1100-1200 yards simply because of the ballistic coefficient of the longer bullets. At 500-600 yards, you're still very much rocking and rolling with plenty of energy.

I'll be trying to convince Randall to shorten and redrill an AA 6.5mm Grendel barrel "real soon now" (tm). The fact that we're neighbors and I can bring steaks and beers may overcome his natural reluctance to work on a Grendel... :)

If you want a bada*s long range AR, build an AR-10 style rifle in .260 Remington or 6.5 Creedmore. Those two calipers blow the socks off pretty much everything else on the AR platform.

6.5mm Creedmore is certainly faster than 6.5mm Grendel with the same chamber safety margins and presumably will eventually have a similar variety of factory loadings. If you handload, it's just faster.

Only one problem is that AR-10's are much less appealing (to me) than AR-15's. Everything is more expensive, longer, heavier, from fewer vendors, and with less agreement as to what an AR-10 actually is. I definitely don't mean this to turn into a AR-15 vs. AR-10 threadjack, but while I'm absolutely interested in accumulating wildcat uppers in AR-15, it's not going to happen for AR-10's.

I do not want to deviate into collecting 6.8 SPC ammo -- but I have an LMT MRP upper with an extra 6.8 barrel (and BCG and magazine) just in case it becomes our issue ammo at some point (and the price comes down -- if ammo is still legal for civilians)

Is .260 Rem in AR15 platform or does that have to be AR10?

I'm a huge fan of the 6.8 and am happy to see things evolve for the better (i.e. improved projectiles, barrel/chamber design, etc.). For the record, I've knocked down steel ram silhouettes @ 550m with authority using hand loaded ammo & 16" WOA barrel w/1-11 twist, DMR chamber. More info can be gathered here: http://www.ar15.com/forums/topic.html?b=3&f=121&t=394382&page=1 or at 68forums.com.

OP- Stay safe & Good Luck with whatever caliber you decide to choose!

.260 Rem is a short action cartridge. AR-10 only.
