Powerman Posted March 21, 2015 Report Share Posted March 21, 2015 I've seen Bison, but don't know much about them. RRA, Yankee Hill, even Stag. Who's putting together a good upper. Looking at getting one. And what about enhanced bolts? I heard there was a guy here that loves 6.8. :) Quote Link to comment Share on other sites More sharing options...

Powerman Posted March 21, 2015 Author Report Share Posted March 21, 2015 I need to ask JP how their capture spring is for 6.8. I would like to know what weight their buffer is. I've seen AR, but didn't see complete uppers. Seems like it's around $800 depending. I would like plug and play, but if I have to swap a couple things it's not that big of deal. Are stronger or enhanced bolts a good idea since the face has to be enlarged? Quote Link to comment Share on other sites More sharing options...

H will build you a complete upper....you can pick out your rail and send it to him ot have him get it Ive used his super bolts and also a stag bolt one time when he was out of stock. :) Wash Quote Link to comment Share on other sites More sharing options...
MikedaddyH Posted March 21, 2015 Report Share Posted March 21, 2015 Ï have a couple Stag bolts,they work fine. H's super bolts are worshipped on the 6.8 forum. Quote Link to comment Share on other sites More sharing options...
Powerman Posted March 21, 2015 Author Report Share Posted March 21, 2015 :) Nice. Anything next to 5.56 is a niche cartridge, but I like what 6.8 has going for it. Quote Link to comment Share on other sites More sharing options...
NTXshooter Posted March 22, 2015 Report Share Posted March 22, 2015 I have a Rock River Coyote Carbine upper in 6.8. Runs flawless on my RRA 5.56 lower. Accurate too. Carbine 16" barrel, Rifle 20" barrel. Quote Link to comment Share on other sites More sharing options...
Powerman Posted March 22, 2015 Author Report Share Posted March 22, 2015 Well finally... I've looked before, not exactly easy info to find. By replacing the steel weights in the JP spring with the tungsten ones, it functions as a H2. It doesn't say I need to change a spring for it. I don't really want to change stuff out. Might have to get another one. Quote Link to comment Share on other sites More sharing options...

Might have to get another one. Powerman On 2 of my 6.8's I use the H2,on the other 2 I use plain ol car buffers and springs with no problemo. but its all in the gas port size too...The H2 buffers do shoot softer and the cycle is tuned better...and guess who has the good stuff? yep, Char does the 6.8 might be a niche,but it makes the .556 feel like a popgun compared to it. I think I read where a 6.8 does 80% of a .308 out to 300 yds...someone correct me if im wrong :) Wash here's some info,but i bet 98Z can tell us the skinny on it Well the chart shows far less on energy! http://demigodllc.com/articles/6.8-mm-spc-cartridge-history-development-hornady-stag-arms-carbine/ found this just now Edited March 22, 2015 by washguy Quote Link to comment Share on other sites More sharing options...
Powerman Posted March 23, 2015 Author Report Share Posted March 23, 2015 I'm loving my AR15.i definitely want a 6.8 now. Zeroed a 1-6 today so I already have the scope. :) Quote Link to comment Share on other sites More sharing options...
washguy Posted March 23, 2015 Report Share Posted March 23, 2015 Powerman lets get it on....6.8 upper get er done :) Wash Quote Link to comment Share on other sites More sharing options...
Powerman Posted March 23, 2015 Author Report Share Posted March 23, 2015 When I was thinking of selling my 308,it seemed like 6.8 ammo was more. I decided on 5.56. But on a AR platform, the 6.8 is nice. 223 for plinking. 6.8 for fun. That's kind of where I'm at. I'll never hunt anything that needs 308. I wouldn't mind hunting some hogs though. Take it on trips to the mountains. I'll be G2G to 300 easy. So far I'm liking ARP. I had a JP bolt in my 308. I know they are not necessary. But with 6.8 opening up the face, seems like good insurance going with an enhanced one. I'm thinking SOCOM profile 16, keymod, my 1-6, and another spring for plug and play. I'll probably just use the CH I have now, but probably another carrier. Any particular break to go with? Flash hider is good enough. I don't need a comp. I got a BCM Mod 0 on my upper. Seemed reasonable for what I want. What is a good GP flash/break? Quote Link to comment Share on other sites More sharing options...
slugger43 Posted March 23, 2015 Report Share Posted March 23, 2015 I used ARP's 18" barrel and super bolt on my 6.8 build, and I'm very happy with the accuracy. There's a very good explanation of what is different about the ARP bolt on the ARP web site. http://www.ar15performance.com/bolts___carriers Quote Link to comment Share on other sites More sharing options...
