I bought the 18" middy 1:7 chrome lined Delton kits a while back. It is currently matched up with a Stag lower and wears an MOE hand guard. I was a little put off by the low price, but it has proven to be a nice shooter. The trigger group sent with the rifle yielded a 9.5# pull, so that got swapped out after the first range trip. I probably have close to 2,500 rounds through this tube, and its a legitimate 1.5MOA rifle with handloads.
I wouldn't hesitate to buy the kit again if I was looking for an inexpensive carbine to put together.
