I'm looking for a barrel & rail

[Tonto]

I'm gathering parts for an AR build for my younger son. It's going to be in FDE, with a spur grip (for now)

I'm looking for a 16" barrel, crowned, no threads.

I also need a rail, in FDE, not too picky on length, just want to cover the gas block.

Any good deals out there?

Whatever you do try and get a chrome lined 1/7 twist bbl, chambered in 5.56. As for rails, try some of the slim line ( Mlok or Keymod) ones with removable piccatinny sections. The smaller diameter will help his grip on the fore end.
