Absolutely pleasure to fire and the recoil pulse is smooth as butter.
I called them up and they gave me an option to do that since I told them its not exactly what I was looking for, but very close.
Which barrel did you have them swap it to? The rifle length Wilson or Shilen?
That upper out of the box comes with a mid length Shilen, which seems awesome, just wish it was a rifle length.
I have a feeling this build is going to get expensive quick.
Edit Add: What length is your rail on the SPR? I thought with the 12" rail that is included with the upper would not cover a rifle length gas system, that's what I was told over the phone.
