Put this upper on my latest build and it's exceeded expectations from the first shot downrange. Andro Corp obviously takes pride in their customer service and support. This has been my third upper from Andro, and all have performed perfectly. Fit, finish, and their cerakote work is done with attention to detail. Thank you for continued excellence.
Awesome upper, and nothing short of excellent when you purchase products from Andro Corp. This upper has performed wonderfully, and my groups at 100 yards exceeded expectations from the first round. Thank you for the outstanding customer service and excellent product line.
