5 of 5 Great upper at a good price November 20, 2020
: SHAWN TITUS from Worthington, PA United States  
I am beyond excited for the upper I received! The build quality is second to none and using BA barrels just pushes it over the top! Thanks for the great product!
I will definitely be back for more!

5 of 5 Always Great Service November 6, 2020
: Calvin MT from Pierz, MN United States  
At a time when it’s tough to get anything 2A related, the service and speed in which it was to my door was again great. Nothing but impressed with the quality of the products. You’d be hard pressed to find better quality in the same parts from some of your higher end companies you’d pay 3x the amount for.
