Ar Build Pistol 10.5 August 16, 2019 : 1517   Hi all. after much research and  thought went into this 10.5 length. Seems to fit current needs and training. Upper arrived in excellent condition. Will provide a solid foundation for a serviceable pistol. Fit and finish are great. All parts attached solidly. Look forward to completed build and training. Would recommend as a mid-grade build. Price point does not do justice to the great quality. Was this review helpful to you?

10.5 inches of Awesomeness !! January 2, 2016 : Christopher D   I personally couldn't be happier. My second upper from Mas Defense and both were delivered very, very fast especially considering my order was during the holids. Item was just as described andexceeded my expectations. I blasted through 100 rounds so far and the upper performed flawlessly. Mated well with my A Lower. Again super fast shipping as soon as order was placed I was notified with order processing and shipping processed notifications. Great Job guys I will defiantly be back.

I love it. March 14, 2015 : John P   This was the perfect upper for my SBR build. 10.5 inch barrel with the Yankee Hill handguard, flawlessly assembled and fits right on to the lower I built. I zeroed in my optic and was driving nails at50 yards. I will never understand why people unnecessarily pay ridiculous amounts of money for something that doesn't perform any better. I will be purchasing all my uppers from MAS in the future. Was this review helpful to you?
