Dropped the bolt and charging handle in with a little bit of oil and went to town no hang ups and extremely accurate with the rifling, was a nice color and durable coating with small bold emblems for finesse. Communication was fast with less then a few hours between questions through emails. Will recommend for future builds!

Here is my problem. I received the merch but, I believe it is missing parts. I received a barrel with a rail but no bolt or bolt carrier group ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- MAS Defense Reply: Tom, every barreled upper listing has the following phrase at the bottom of the description: "Bolt Carrier Groups and Charging Handles are sold separately". Thank you for your business and your feedback!
