Uintah Precision produces the only true bolt action, precision upper receiver for AR pattern rifles. Compatible with LR-308 and AR-15 platform rifles, UPR10 and UPR15
bolt action uppers simply pin in place of your existing upper receiver. No modifications or changes are needed to your lower receiver and they feed from standard magazines.
Blending the familiarity and modularity of the AR with the precision and accuracy of a bolt action, Uintah Precision brings you the best of both worlds. Both models are compatible with most aftermarket accessories, allowing shooters to customize their weapon like they would any other AR pattern rifle. From hunting to long range precision, or even compliance within heavily regulated states, the Uintah Precision UPR can fill all roles. Check out how easy it is to install the UPR in the video above.
The UPR-10 and UPR-15 are both made in the USA, and are offered in Left or Right handed variations. UPR bolt action uppers are essentially custom barreled actions that pin to AR lowers. Being such, the shooter will be able to maximize accuracy and control with the UPR complete bolt action upper, as all of their training and muscle memory will translate directly over from their use of the most popular gun in America, to a long range, precision bolt action rifle. Our guns are guaranteed to shoot 1 MOA with factory match ammo, but with a skilled shooter, are capable of shooting much much better.
