I am currently building up a new AR in 6.8SPC.
My question is, among the current crop of suppliers, who makes the best upper assembly in 6.8SPC?
HELP!! There are so many to choose from.

I just got a 16 inch chrome lined upper from Tim at Ko- tonics. It was my first 6.8 and it has proven to be very accurate with a variety of bullets. I have no experience with other suppliers in 6.8 to compare the Ko-tonics with, however, I do have numerous ARs of different configurations and calibers. The Ko-tonics has became one of my favorites very quickly. Friendly service too!

I went with a custom barrel manufacture. - ar15barrels.com - Randall Rausch

Thanks for the feedback! The Ko-Tonics products sound good according to other postings. Does anyone have experience with RRA, DPMS, STAG or BM?

Ko-Tonics and Denny's Guns would be my top choices.  I have one of Denny's guns 16.1" barrel with the 1:11" twist and it has no problems handling the hottest loads I muster up.

Have been reading other topics and it looks like Ko-tonics for me.
Thanks to all who recommended them.

All of the above vendors are great people to deal with. If you are looking at other mfg's: Barrett and LWRC which I personally own and had no issues with FTF, FTE and accuracy. Actually both are the one I prefer to shoot on a regular basis. My LMT MRP 6.8 rifle is pretty much a safe queen which I plan to sell soon.
