Youtuber GarandThumb sent us a photo of his AAC MPW upper build. He wrote …

I had a spare spike’s lower laying in my gun safe that I’ve neglected for a long time. Finally took the time to complete the build with a AAC MPW 5.56 upper, which comes with a KAC URX 3.1 and Blackout 51T. In addition I have added a EOTech EXPS 2-2 and magpul BUIS. The BCM gunfighter stock was the only gamble as I’d never seen and or tried one before ordering it. However BCM has done it again and the stock feels excellent. It’s a fantastic rifle and will serve me well in competitions to come.
