    UD7 remington 700 6mm PRC received my chassis so fast. I think they sent it two days before I ordered it. It looks great if I had a question somebody always pick up the phone. I looked at a lot of online reviews people that never had one had questions but people that did have one said they were great.

    UD7 Ruger American Gen 2 6mm ARC. This rifle always shot good but I don't think I ever saw an impact with the OEM stock. Mounted in the UD7, now I see every one. Out of the box this rifle could shoot killer groups, just not every time. In 50 shots it would put up a 1/4 MOA and a few 1/2 MOA 5 shot groups. The rest could be over MOA. Not any more, I can blame that all on the plastic stock. By the way customer service is great, friendly and do what they say in a timely manner.

    I bought the 7 slot chassis and built it like I wanted, I simply love it, it came out so great, will be a precision 308 when finished…

    I’m using the UD 7 slot chassis with a CZ 457 action and couldn’t be happier. It’s a solid chassis that’s light weight, handles great and looks amazing for a fraction of the cost.

    This thing is amazing, really put new life into my build. Only knock on it is it came with a ding in the aluminum....... wouldn't be a big deal to someone who isn't a stickler for perfection, but to my eye I can see this flaw from a low earth orbit....

    Hmm. Got it for a bergara b14. The fit and finish is what’s expected for a mid grade chassis but the trigger mechanism pretty exposed. I build this rifle for hunting but that’s gunna get pretty dirty. Pros: weight, cost, colors, fast shipping Cons: fit and finish(already is scratched), did not come with the grip screw.

    I put the barreled action from my Bergara HMR 6.5 CM into the UD chassis system with the light bag rider, spigot, and right hand thumb shelf grip. That lightened up the gun by 2#s. I changed the scope and the gun is now weighing in from 15#s before to 11.4#s now. The stock is a great quality stock at an affordable price. I emailed back and forth a couple times to arrange for the parts I wanted and got very timely responses. Great company to work with! Thanks guys. I couldn't be happier.

    First time purchase. Will never buy another brand. When I have had the rifle out, people who have shot it comment on how easy it is to get behind the rifle. The ergonomics are outstanding. Not all my rifles are like this. By comparison, people have to work at getting set up right behind other systems I use. Maybe optics / eye relief, but I feel it is the chassis - stock, grip, etc. At the price point - design, features and ergonomics are unbeatable. Oh, and customer service is out-of-this-world. Fast, responsive and sincere. True American Ingenuity. Thank you!
