Ultimatum Precision Releases U300 Bolt Action

Ultimatum Precision, a high-end bolt action manufacturer, located in Abbotsford, BC, Canada and Washington State USA, has released news of their new bolt action design, the U300. At a glance, it appears to be nothing more than a slicked up custom Remington 700 action, but further inspection shows that it has some rather nice features.

While it does fit into a Remington 700 action footprint, the U300 features a removable floating 3-lug bolt head, a 5/16″ integrated recoil lug, made from 4340 steel, AICS magazine compatible, and a 20 MOA picatinny rail secured with six bolts and two dowel pins. Ultimatum says that a long action and a .338 specific model will ship later this year, but no concrete date has been given.

The Ultimatum team appears to be comprised of passionate precision shooters that wanted a commercially available action that checked all the boxes a precision shooter might want to be checked. If you are looking for a custom action to start building a precision rifle that uses R700 stocks and triggers, it might make sense to take a look at the U300. It does offer some nice features and looks pretty damned cool to boot.

You can learn more about the U300 at Ultimatum Precision‘s website HERE or take a look at the video below. MSRP for the action starts at $998 on up to $1098 depending on options. The U300 is also available in a left-hand model for southpaws.

    At first glance, it looked like this upper would fit on an ar.. if only.

      Would be a waste of a good action to put it on an AR lower 😉 😛

      It does look like it.

      I imagine it could be done, putting a bolt action on an AR lower, and you could even make it in a way to allow it to fit tight into different lowers… Use some adjustment screws or something.

      Do it right and you can even use existing barrels, just need a compatible bolt design.

      Plus advantages of ready mags and parts… And some truly nice triggers.

        I’m sure I’ve seen a user submitted drawing on tfb for a bolt action big bore upper for the AR platform with a transverse mag sticking out the left side to free you from the tyranny of the magwell.

        I don’t know if the .50BMG single shot bolt action AR uppers have good reviews. It looked like a good way to bend your receiver extension/buffer tube.
