AMAZING November 20, 2020 :   This upper is absolutely perfect in every way, looks, performance, and comfortability. I ordered this to build my first rifle and could see this setup on many of my rifles in the future. Very sleek, comfortable to grab, lightweight, and very sturdy and strong. Would absolutely recommend this upper! Was this review helpful to you?

Love it. November 16, 2020 : Nikki B from FL United States   Great price and they even installed the charging handle and bolt carrier for no extra charge . Everything arrived within a week which for something that is built and test fired  I can't ask for better. Great experience for assembling my first AR. Was this review helpful to you?

MasDefense is the best November 5, 2020 : Darick L from Lone tree , CO United States   I’ve ordered some small thing here and there from MasDefense and everything had always been high quality and awesome. My brother in law built his first AR-15 using MasDefense and the gun performed amazingly. After seeing how well it performed I decided to build my own. The upper just came in the mail and the quality is just as expected. Keep up the good work! Was this review helpful to you?

Dope..... October 16, 2020 : Brett Gearhart from Ottawa, KS United States   Honestly, probably the coolest looking gun I’ve  built to date. Yeah only issue (sorta) is that the handguard wont allow for total movement on the lower receiver. Only opens up 45 degrees ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- MAS Defense Reply: Brett, some lowers have longer pivot pin lugs than others. The handguard has a angled cut to allow movement on most lowers. If yours still hits, you can loosen the handguard and push it forward a hair to clear the lug. Thank you for your business and your feedback! Was this review helpful to you?
