I bought this upper to complete a pistol build, it looks incredible in person and feels as quality as my DD MK18 upper for around half the price. Bad Attitude Dept. is doing great stuff with their products and I’m proud to have this pistol build. Have had no malfunctions in over 3k rounds. Special shout out to Joel, this was sold out when I purchased it. However he hooked me up and allowed me to purchase one with a small blemish in the clear anodized upper receiver, when he said “small blemish” it’s entirely unnoticeable to the human eye. The fact they wouldn’t sell this normally goes to show the level of quality and pride these guys have for the products they sell. Here’s to hoping we get a rerun soon, would love to get the 16” upper as well.
