Last week I followed one of Bristoe's links and found this. J&T Upper

After a couple days shipping delays it arrived yesterday. I'll work it up and shake it out...

Report to follow...


Ok... My kid and I put a couple hundred rounds through it. Function is great. Trigger kinda sucks.

Yesterday I went to the local fun store and bought the only rear sight available on short notice. It's a folding polymer/plastic bodied aperture from mag-pul. I will put a fixed metal bodied sight on it soon.

Accuracy is OK... Sorta... Maybe the pencil barrel heating up, or maybe that flip up sight shifts, but after a couple or three rounds groups open way up.

This is at 100 yards.
