Yup. I ran a standard carbine buffer in one of my 6.8 builds, and the other uses an A2 stock, so a standard rifle buffer works, too.

He I don't mean to derail the thread or anything but does any one know how worried I should be about firing corrisive ammo through a melonite treated ar chambered in 5.45? Keep in mind I clean my weapons til there is no carbon to be found by military style inspection shortly after I arrive home from the range. The range is usually the myrtle grove shooting range in la plata and my house is between bowie and crofton. Usually takes around 45min-1.25hours. Also should I use more than just a bore snake to clean the barrel?

Any larger pistol calibers out there ? 357 / 44 mag ? If I do a pistol/commando I want something different.

Uppers are available in 10mm and .45 ACP and .410. The problem with the magnums you listed is they are rimmed cartridges, so feeding through AR mags is a problem.

Talk to Tony at Tromix, he's done uppers in magnum calibers. The man is a wizard at unusual AR variants and calibers.

I've seen in this thread talk about the 6.8 spc. AR with standard and H2 buffers. I am wondering about the 7.62x39mm upper. Does anyone have any recommendation for it?

Standard Carbine Buffer and Spring works fine.

My reading told me the standard vs H2 is totally dependent on the gas return and powder charge you use. The more pressure your round throws it may not be as crucial as the gas return will be sufficient to rack the next round. The larger the round the less gas can return meaning it may have issues so the coil system you use comes into play.

Magazines are made by Barrett, PRI, and C-Products. The Barret is a true 30-round magazine, stainless steel, and cartridges must be 2.260" COAL or less to fit in Barrets. C-Product mags are basic, stainless steel magazines and hold 25, 15, and 5 rounds. The max COAL I've had work with these mags is 2.285". PRI makes stainless steel mag, 25, 15, and 5 rounds. You can load out the cartidge to 2.300" COAL. Of the three magazine makers, Barret makes the most reliable, followed by PRI and then C-Products.
You will want the PRI mags if you intend to try out the new Berger 140g match ammo that is supersonic at 1000 yards as they are the only mags that support the increased OAL of that cartridge.

Question about the 6.8 as well. I noticed there is no mention about the lower. I am assuming a 5.56 lower will work. Are the 6.8 mags fitting in the mag wells ok?
