TNW CQB upper w/gas piston system

[JOAT 0311]

These uppers will work w/most of the lowers. There is so much AR stuff on the market Its never a good idea to say all. TNW offers a 20" and 24" stainless barrel for pinpoint accuracy. I am trying to get my hands on more of the barrels and bolts available. Accuracy is fine w/the 16" I am patiently waiting to try the 6.5 set up. The barrels are very stable and the locks work very well. It is nice to be able to change barrels w/the tip of a bullet or a key.
