Verified buyerThis is one of the lightest 16" uppers I have. The HWK from STNGR, the barrel and receiver from AT3 look great together. They didn't use cheap parts you can see this in my full review video on
my channel.

Rick Stark Verified buyer
I was left with the impression that the gas block, flash hider and dust cover had been used or laying around for a while in the open air prior to assembly as the finish on all three was not new. I do like the looks overall and am hoping for a long service life. I was very impressed with how fast out the door it was to me (I received it from UPS the very next day! I do live just down the road in Sartell. If you look you will find I have made another purchase from you on Friday and it looks again like I am going to get superb service. Interestingly, I have made three purchases from Palmetto State Arsenal on Friday also and you are out hustling them on getting the product to me. I wish you much success as I am impressed with your response to me and will hold you in high regard.
