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....

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.

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…

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.

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.
