Reviewer: Paul Molini from Wichita falls, TX United States  
was impressed with the quality of the upper.  fit perfectly on my Bushmaster lower, no slop, simple swap out.  well machined, bore looked smooth and well defined.  took to range this past weekend, and fired with hornady black 110 grain varmint load, and hornady 120 grain sst load.  both loads were accurate, the Black load better at 100 yards, the SST load putting 12 rounds into 2 inches by 2 inches at 50 yards.  put a 3x burris reflex sight on it, so somewhat handicapped at 100 yards with my aged eyes.  not the rifle's fault.  overall, very please with the unit.  thanks.

5 of 5 6.8 SPC II - Stainless Upper Assembly September 19, 2018
Reviewer: Dom from Gunpowder, MD United States  
Purchased upper complete with BCG and it arrived in two days. It was finicky with ammo and cycling.  Spoke to the warranty folks and sent it back. They turned it around in 48 hours and I had it back the same week.  Not sure what voodo they performed but it cycles now as it should.  Shooting clover leaf groups at both 50 and 100yrds.  Great service and excellent product.
