The .224 Valkyrie Uintah Precision UPR-15 Arrives!
The brand new Uintah Precision UPR-15 chambered in .224 Valkyrie has arrived!
I have received the brand new UPR-15 upper from the Utah based company Uintah Precision. The UPR-15 is the second offering from the company; it is a bolt-action complete upper for an AR-15 patterned rifle. With the push of two pins you can take off your semi-auto upper and place the UPR in its place, changing it to a bolt-action in just seconds. After shooting my UPR-10 (the AR-10 version) with such great success to distances as far as one mile I am more than excited to get shooting with the new upper. These uppers will be offered in .223 Wylde, .224 Valkyrie, 6.5 Grendel and 300 AAC Blackout. Be sure to scroll to the bottom of this article for full resolution pictures!
The UPR-15 Specs
This upper has a few differences from its big brother. One of the biggest changes is the brand of barrel used in the upper which has been sourced from another Utah based company, Match Grade Machine. My UPR-10 has a Shilen match hand lapped barrel. The UPR-15 is equipped with a 22″ long 1:7″ twist barrel chambered in .224 Valkyrie. All barrels will come with 1/2×28 threaded muzzles with thread protectors. I have equipped my UPR-15 with the muzzle rise eliminator brake from Witt Machine. The upper has a fully free floated 12″ hand guard loaded with M-LOK cutouts. The AR-15 upper has a newly designed bolt that has improved on any shortcomings of the UPR-10 bolt. Built with feeding and dependability in mind. The bolt is also surprisingly slim and light weight in comparison to a standard AR-15 bolt carrier group with a significantly shorter length. It has a 3 locking lug action for the highest strength and accuracy performance possible. The upper receiver has a zero MOA flat top Picatinny rail which diverges from the built in 20 MOA found on the UPR-10. It uses a standard AR-15 firing pin, so if anything were to go wrong parts will be extremely easy to source. The bolt face is home to the Remington style ejector and plunger for strong reliable ejection. Uintah Precision has had a test rifle chambered in .224 Valkyrie and they have posted some very impressive groups with the Valkyrie and the Match Grade Machine barrel. I am interested to see if the 22″ barrel can get near the claimed velocities of the cartridge.
.224 Valkyrie cartridge info.
I am very excited to get behind a .224 Valkyrie and see how the most recent cartridge offering from Federal performs. Likely you have heard of the claims of the new long-range 22 caliber cartridge. Federal boasts 1,300 yards supersonic range with the Sierra 90 grain Matchking, and I intend to see how it performs at long-range. I have a few boxes of factory Federal ammunition that I will be taking out and testing. I have purchased Federal Gold Medal Match loaded with the 90 grain Sierra Matchking hollow point boat tail with a ballistic coefficient of .563 G1, and one box of the 90 grain Federal Fusion which is a soft pointed hunting bullet. I’ve had great luck with the Fusion line in my .243 Winchester consistently shooting sub MOA. The final ammo will be the American Eagle 75 grain total metal jacket which is the most affordable of the .224 offerings. I am curious how the velocities and groupings will compare to the match ammo or hunting line. Hornady has announced they will be making .224 Valkyrie with a new 88 grain ELD-M, and once that is released I will definitely try it out and get some information on velocities and accuracy from my rifle.
I will be taking the Upper out on its maiden voyage very soon! The first trip will be mainly focused on getting the scope zeroed, some velocity data from all the different lines of ammunition and shooting for groups. I will also be following up with getting into reloading when my reloading dies arrive and I have some components to put together. Thank you very much for checking out The Reloaders Network.
