I have just started working on my build and was wanting to do something with the .300 Winchester Short Magnum (WSM). I had a question about compatibility, so I called, and they were extremely helpful and knowledgeable. The fit and finish of the chassis, light-weight butt stock, and the grip seem to be outstanding. I am very impressed by the build quality and weight (or lack thereof). My only concern is with the recoil pad. It seems a bit stiff and knowing that the .300 WSM packs a punch, it may be inadequate. Time will tell. I DO like the other accessory options available and will likely be purchasing a few of those to make this thing perfect.

I just ordered my 5th ULTRADYNE chassis, buttstock and grip. The first was for my 12 yr old son that likes to shoot off a tripod. Turns out that I like it too! I started converting our guns to utilize the stability and accuracy of the the tripod and chassis combination. The chassis has helped the accuracy of several guns and the tripod is also a reliable platform for hunting accuracy at longer ranges. The ARCA attachment provides fast and secure attachment to the tripod head, which is perfect for hunting and getting a young shooter in position. I would like to see an upgraded recoil pad, especially for my son. But overall I think we have significantly improved our hunting system and I have been very happy with customer service, shipping times and most importantly - product quality.

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!

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.

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.
