del-ton gets my vote
Scoots-
The upper that I got from Del-Ton has and Olympic Arms barrel. It came completely assembled and ready to run. I did not have to do anything to the upper. It came with a low profile gas block that is mounted under the handguard(s). In the original configuration, the upper had a D-ring barrel nut and split handguards. The forward handguard retainer clip was held in place by a picatiny rail that was mounted on the barrel where the carbine length gas port would be.
As far as I can determine from calling Olympic Arms, the current Olympic Arms barrels come with the gas port in the pistol position and are not threaded for a compensator or flash-hider. This was the case with the barrel that I have.
Subsequently, I upgraded the upper and installed a free-float tube and an adjustable gas block from JP Enterprises. I also had Randall at ARbarrels.com thread the barrel to 5/8x24... the same thread pitch for AR10. I believe that all I have to do is unscrew remove the compensator and screw on a suppressor. Unfortunately, the state I live in does not allow us peasants to have suppressors :(
In an earlier post on this thread you wanted to know about the thread pitch. I talked to Tony a Del-Ton...(I am thinking of buying another upper in 300-221 fireball with the gas port in the carbine position) about the tread pitch. He told me that the Olympic Arms barrels (like mine) are not threaded and that the other barrels he carries, the ones with the gas port in the carbine position, come threaded with some weird pitch. I think he said it was the same pitch as on the 7.62 AK barrels. You probably should call him to clarify this.
I hope this helps
