So in June I emailed bushmaster about when they would have 6.8spc barrels available for order,
they said August. Now I emailed and they said its still in development, what the hell the whole resin I
bought an ACR instead of a SCAR was I thought it was going to muilt caliber, well that and I don't like the
reciprocating charging handle. Anybody know whats up with bushmaster or if another company has
planes to make ACR barrels?

2012 will deal with your 6.8 availability issues, I believe.

Hope your correct, but we have heard this for the last 2 + years. " Were releasing them in 3 months"

You may have a point.

step 1 take out your barrel assembly

step 2 send it to any barrel manufacturer

step 3 ask for a 6.8 caliber barrel with the same outside diameter

step 4 order a 6.8mm bolt and magazine

step 5 reassemble all parts

step 6 add ammunition to the magazine

step 7 shoot

step 8 optional tune gas port size if needed.

step 9 quit yer bitchin

come on Stomry you sounded so knowledgeable until this post. You should know that the ACR Bolt is different than a standard AR bolt so unless BM is going to send you one or let you buy one. All of the above is quite useless, but hey its the thought that counts I guess.

Yea, it does.

Until you realize that by opening up the bolt face, you weaken it. A lot. And when you machine it, you'll screw up the heat treat, shot peening, and input a lot of stresses that were not present before, making it alot weaker. Will it work? For a while, and good luck getting a replacement 5.56 bolt.

BM's been sitting on mine for 10 weeks, and guess which part is 'backordered'. . ..

uh apparently some people don't like to read - currently most 6.5, 6.8, and 7.62x39 mm bolts start out as standard ar15 223 or 556 bolts and then are put on a lathe and the face is machined out. If you call up teppo jitsu and order a custom caliber chances are the same thing is going to happen.

This is what a standard 556 bolt modified to shoot 6.8 looks like.



Also milling a bolt brings it nowhere near the temperature sustained firing does so the heat treat is no issue and re coating it is pretty simple too although I run into 6.5 and 6.8 bolts that were never re coated and work just fine. I've got 10,000 rounds through a 7.62mm pistol I never bothered to have coated after I received it with a modified bolt in kit form.

Also I was one of the first people - in the first 500 to own an acr and I have already shot a 6.5 Grendel acr that worked flawlessly.

i say pics or it didnt happen, not saying that he's fos, but its very unlikely he happened to snag one of the only 6.8 acr's in existence

^^+1 i retract my previous statement, looks like he might really have it

He has numerous pics that look LEGIT although Bushmaster's website is still mum on the topic and there are none showing up on GB, Impact Guns, or any of the other sights that do double mark-up for the first of anything.

Interesting
