Aero Precision Lower reciever with a Del Ton Lower Parts Kit. The buffer tube/receiver extension is a regular collapsible type covered with a foam pad that came with the Pistol Tube that I didn't like at all.
A lot of parts here. It was a few more before I added the forward assist and ejection port cover to the Aero Precision Upper Receiver. You're looking at a Del Ton 7.5 inch 1:9 twist chrome moly barrel, Yankee Hill Machine carbine free float lightweight quad rail and end cap, Rock River Arms bolt and bolt carrier group and in the upper right zip bag is a Midwest Industries low profile gas block. There is a pistol length gas tube and gas block pin and a Yankee Hill Machine Phantom flash hider just out of the picture.
Here is a right side look at the nearly finished product. The A.R.M.S. flip up sights are on backorder.
And here is the other side. I haven't decided whether to keep the light on the left side or the right side. I have a pressure switch for it so I have options. I haven't shot it yet and will wait until I check the head space first.
Never know what I'll put on it.
