As for AR15s, I have them in 5.56, 308, 300BO, 7.62x39, 9mm and .45ACP. I wanted something else, not crazy expensive, so I did research on 6.8 and 6.5, I decided on 6.8 for a few reasons. It hits harder than 5.56 and weights less than 308. 6.5 Grendel performs better out of longer barrels and at distance. The 6.8 was designed as a shorter range round which I like. I do not and cannot shoot long range.
When I read about the SIX8 I said that's the one. I even handled one but did not get to shoot it. Well too much money, it's the way to go but only if you got the bucks or plan on keeping it as a go to gun. I get bored easy and like to change things up and around. So I figured I'll build one since me and my gunsmith friend have built so many already in various calibers 6.8 seems like the next step. He was skeptical but I convince him the bugs of the past have been worked out.
It seems most run without any major problems if you just like any firearm build stick to compatible and well made parts.
My plan is to get a ARP 16" barrel and one of their BCGs. It looks like they also have a bigger bolt head and matching barrel extension for it if you want. I might go in that direction. Right now they do not have a barrel in stock. And I am not crazy about the profile. I prefer a thicker barrel to be honest.
Or I can get the Wilson Combat 16" or 14.7" barrel. A NiB M16 carrier and a LWRC bolt. Those are the important parts, a mil-spec upper and BCM charging handle are all that's needed, some PRI 10rd & 25rd mags and go shooting. Use one of my other AR lowers for now.
So I have a few questions I would like to ask? Things that have not been answered in all of my readings about the round and how it works in an AR15. One question surrounds the muzzle device. From experience even though it fits the thread it doesn't mean it works well with that round. VG6 precision makes a 6.8 specific brake. I have a few VG6 brakes on my rifles and they work better than anything else I tried. On some of my 5.56mm I use the BCM gunfighter since a pure brake isn't really necessary on a light shooter. I like that the BCM works well as a brake, comp and hider on 5.56mm, didn't like it all that much on the others and the VG6 worked much better and louder unfortunately. Once you go up in recoil a true brake is good and their 308 and 300 BO works well, the 300 BO even works well on my CMMG Mutant. I do have a 308 BCM laying around, has anyone tried it on a 6.8? Has anyone tried the VG6 on their 6.8?
Next is ammo, is there a place that supports the 6.8 and has 6.8 ammo in quantity and choices at a good price. I usually go to SGA for my ammo, I'm in central Texas so they ship fast, have a good price and selection for most ammo needs. I see the well dried up for cheap XM68 but Sellier Bellot makes some good stuff and for hunting/self-defense Hornady and Federal are supporting 6.8 and there seems to be ammo available. Any other manufacturers out there? Especially for plinking, under $15 a box of 20? I have been checking ammo seek and everybody has the same stuff at varying prices. I forgot I also see SSA has some good ammo available also.
So I'll probably start the building of an upper once I get an idea of when ARP has those barrels in. Get some PRI and Barrett mags, a couple 100 rounds of various ammo and let er' rip.
Any input would be appreciated especially from personal experiences with those barrels and bolts as well as mags and ammo. Thanks.
