Just got my chassis tonight, and its freakin awsome. I was skeptical of the quality becouse of the low price, but damn. This thing is beautiful, the machining is excellent, no blemishes, the anodizing is perfect, not gloss, not matte just a perfect satin black. Im super excited about my ultradyne chassis, and very glad i didnt go with the rival arms one over the ultradyne chassis. The built in arca rail was the seller for me. Thank you guys for such a quality product at 2/3rds the price of your competitors.

For a low-end chassis, my UD5 is highly impressive. It now has a side-mount bipod, pistol grip and 4-way adjustable buttstock. Anxiously awaiting my Savage 6.5 to come back from my Cerakoter, and range day. I'm about to order a UD bridge for for it also. This UD5 is an OUTSTANDING piece of equipment for anywhere near the money!

Awesome Chassis. I own an MDT LSS Chassis. It is very similar and somewhere between the 3 and 4 slot UD Chassis. I can say the Chassis are very similar, but the Ultradyne exceeds it in multiple way. Better price, more color options and it comes with useful features like Arca rail and the ability to add adapters to the end. If you are considering the MDT LSS or LSS-XL this chassis beats them hands down. Machining and cerakote is perfect, its less expensive and it weighs less. Only thing I can see that needs improvement is adding more actions like the Remington 783, Howa 1500, and Howa Mini. Also, A folding stock adapter would be an awesome addition

I bought the UD5 and a spigot and it is perfect. Not super long but the spigot gets the bipod right where I want it. Overall quality, fit and finish are amazing. Anyone on the fence about one of these chassis don’t be. You will not go wrong with Ultradyne products. Joe S.

Very well made chassis. Very lightweight for what you get. Have it on a Vudoo rimfire and works well.
