[320pf]

I got my barrel and upper receiver, bolt and bolt carrier group from Del-ton. It is a 16 inch stainless steel barrel from Olympic Arms with the gas port is in the pistol position. I went with a low profile adjustable gas block and recoil compensator from JP Enterprises. Originally the barrel was not threaded. I sent the barrel to Randall at AR15 barrels.com and had the barrel threaded to 5/8x24. This is the tread pitch for AR10's

Randall did a very nice job on my upper... turned the job around in about a week.

I set the gun up in the Dissipator configuration by installing a full length free float tube.

Toni at Del-ton is a great guy and will set you up with a nice upper.

Here is a photo of my upper. I use a EOtech holographic site or a Barsk 1.5 to 6x variable scope
