Uintah Precision UPR-10 Bolt Action AR-10 Upper Assembly 6.5 Creedmoor

Read Gun Tests Rating and Recommendation

GUN TESTS GRADE: B+
Capable of very good accuracy, this was a dream upper in need of a little refinement. This makes it possible to have a matched set of semi-auto carbine and a bolt-action precision rifle.

The Uintah UPR-10's firing pin in the forward position appears recessed. The bolt-action upper utilizes the same floating firing pin as an AR-10.
Here the firing pin is extended. Held by the same hardened steel cross pin as in the semi-auto AR-10, the firing pin was free to float about 0.12 inches. We found the bolt knob to be unnecessarily abrasive. Note the underside of the bolt was relieved to skip over the bolt lock/release found on the lower.
Our only problems with the UPR-10 centered on feeding the ammunition into the chamber. We think double feeds were the fault of the extractor (arrow) being under too much tension. Or perhaps the claw itself needed to be smoothed.
