Best complete upper I’ve ever purchased. Craftsmanship is superior to other companies in the industry. Customer service exceeded my expectations as well.

Bought this upper separately in July of 2017 because at the time the UDP-9 was only available in keymod and I was trying to phase my keymod out.
I was impressed from the moment I received the upper. Fit and finish is amazing. I planned to cerakote the build but it looks nice enough already, so I may put that off.
I now have (probably) about a thousand rounds through this upper and it has worked flawlessly even through my light and +p handloads. Some of the most fun I’ve had with an AR in a while.

Good looking upper. Worked like a top first time fired.

Great upper. Truly impressed with quality. I had purchased a upper and lower set but later decided to have the entire upper assembled.

No issues as of yet. Will update if need be. First impressions are great. Fired 200 rounds first day with zero issues from the upper.

This upper is so well built my credit score went up after I bought it.
Jokes aside I am glad I paid a little extra for a quality upper. First day at the range I shot around 200 rounds of Magtech 115gr fmj’s through it and it was driving tacs at 30+ yards with iron sights. I put a crimson trace laser on foregrip and it’s deadly accurate.

Wow, Fantastic upper. Attached it to the Angstadt lower I built and it runs flawlessly. Already have 300 plus rounds through it.
I had some issues with an off brand upper (FTF) and David and Rich were excellent in their support and trouble shooting. Now I have an eight inch and six inch 9MM that shoot great! You guys Rock!!
