Uintah\u2019s UP-10 blends AR ergonomics with bolt-action precision, staying compact, quiet, and flat-out useful with both subsonics and supersonics.<\/p>\n

Meet the UP-10: Bolt-Action AR Control With Real Accuracy<\/strong><\/h2>\n

The UP-10 is Uintah Precision\u2019s flagship rifle. This gun shares many similarities with an AR-10, but it\u2019s bolt-action instead of semi-auto. Why would they do that? Well, bolt action platforms are inherently more accurate than semi-autos, and they suppress nicely! The UP-10 that I\u2019ve spent years testing is an 8.6 Blackout with a 12.5\u2033 barrel and a collapsible SBA3 brace from SB Tactical. This gun is compact and capable of shooting a wide variety of projectiles. I tested mine with 220-grain supersonics to 350-grain subsonic ammunition. The UP-10 rode shotgun in my truck for months on end because it was capable of shooting a hard-hitting subsonic round, or a further-reaching supersonic, without any modifications to achieve reliability. I even took game animals with this gun, proving its lethality.<\/p>\n

This gun maintains a compact profile even after adding a suppressor to the muzzle. Also, because the UP-10 uses a standard lower receiver, I can easily swap the upper for a semi-automatic AR-10 upper, only requiring the addition of a buffer and spring. But, before I continue to talk about the UP-10 in 8.6 Blackout<\/a>, I think it\u2019s important to also discuss who Uintah Precision is, what they stand for, and what their warranty covers.<\/p>\n

My UP-10 in 8.6 Blackout has a 12.5\u2033 barrel, which makes it lighter weight and more portable. Due to the versatility of 8.6 Blackout, it remains very capable in many situations.<\/figcaption><\/figure>\n

Who Is Uintah Precision and Why This Design Works<\/strong><\/h2>\n

Let\u2019s learn a little about Uinta<\/a>h Precision, starting with their name. Uintah (pronounced YOO-IN-TAH) arises from this company\u2019s geographic location in the Uintah Basin of the Uintah Mountains of Utah. Originally, Uintah Machine made coal mining machinery. They swapped to precision rifles when coal mining slowed down, and there was less demand for their products in that industry. When they pivoted from coal mining machinery to firearms, they weren\u2019t simply chasing money; their founder, Richard Hamilton, chased his passion. Using the Thomas Edison approach to invention, they attempted 975,000 prototypes to make the perfect modern bolt-action, and finally succeeded. Today, they offer bolt-action AR15 and AR10 platforms (aptly named the UP-15 and UP-10), semi-autos of the same type, a muzzleloader, and even a cannon!<\/p>\n

Warranty and the Sub-MOA Promise<\/strong><\/h2>\n

Uintah warrants all receiver assemblies to be free of defects in workmanship and\/or materials for the life of the receiver, bolt, and barrel extension nut. Also, if you are not happy with the upper\/firearm, return it within the first 30 days for a replacement or full refund of the purchase price. However, any work done to the receiver assembly by anyone other than Uintah Precision voids all warranties. Uintah also guarantees sub-MOA accuracy, measured by 3-shot groups at 100 yards with match-grade ammunition.<\/p>\n

Ordering the Standard UP-10: Options That Matter<\/strong><\/h2>\n

As stated, I have a UP-10 in 8.6 Blackout with a 12.5\u2033 barrel, 12\u2033 handguard, and SBA3 brace. If you want to order this same gun, you can. Go to Uintah Precision\u2019s website<\/a>, under \u201cUP-10 complete Rifle,\u201d you can input if you want left or right-handed, what caliber and barrel length (15 standard options to choose from), barrel material, and trigger type you want. Any firearm with a barrel length of less than 16\u2033 will come standard with an SBA3 pistol brace.<\/p>\n

\"SBA3<\/source><\/picture>
Any firearm ordered from Uintah Precision that has a barrel length of less than 16\u2033 will come standard with this SB Tactical SBA3 brace.<\/figcaption><\/figure>\n

The combo I have runs $2,425.00, and the most expensive standard option goes up to $2,950.00. To jump into this higher price range, you need to select a carbon fiber barrel option. If you desire anything other than what is on the standard list, just call in and ask! The guys at Uintah enjoy a custom build as much as you do.<\/p>\n

The UP-10 doesn\u2019t just look like a bolt action; it\u2019s a true bolt action with a 3-lug bolt and 60-degree throw. There are other bolt-action AR uppers out there that appear to be a true bolt action, but aren\u2019t constructed in this way. The upper and lower are also machined from 7075 billet aluminum.<\/p>\n

\"Closeup<\/source><\/picture>
Here\u2019s a closer look at the bolt used in the UP-10. This bolt features a 3-lug, push feed design.<\/figcaption><\/figure>\n

The upper features a 20 MOA rail and Preferred Barrels 416R stainless or carbon fiber barrel. The lower comes with a 3lb Uintah Vitrum single-stage trigger, Magpul K2+ grip, and PRS Lite stock (for orders with barrels > 16 inches). The UP-10 ships with (1) 10-round magazine and comes in a Savior Rifle Range bag, while full-length rifles come in Savior Specialist LRP bags, and pistol-length firearms come in the Grey Savior Covert bags.<\/p>\n

The UP-10 is compatible with DPMS LR-308 patterned semi-auto uppers, so feel free to mix and match your uppers and lowers in all legal possibilities. And finally, the cherry on top: These firearms are 100% made in the USA!<\/p>\n

My 12.5 Inch 8.6 Blackout Build and Setup<\/strong><\/h2>\n

Again, the UP-10 I have tested is the 12.5\u2033 8.6 Blackout. This gun has a 12.5\u2033 416R stainless barrel threaded 5\/8\u00d724 at the muzzle. I chose to suppress this gun with a Diligent Defense DTF-STI 8.6mm suppressor<\/a> and mounted an Arken SH-4 GenII 4-16\u00d750 optic. These accessories were picked because the DTF-STI is a lightweight, high-quality suppressor that keeps the 8.6 Blackout comically quiet, and the Arken 4-16 power optic is an affordable yet capable optic with a power range that is conducive for close-range subsonic shooting as well as extended range supersonic engagements.<\/p>\n

\"UP-10
I can\u2019t think of a better firearm to use around the farm. The UP-10 in 8.6 Blackout hits hard and is extremely quiet when paired with a quality suppressor like the Diligent Defense DTF-STI.<\/figcaption><\/figure>\n

I chose 8.6 blackout purely because of the variety of ammunition available in supersonic and subsonic types. I wished to have a rifle that I could hunt with and use either subs or supers, depending on the situation or opportunity presented. The lethality of a subsonic 280-400 grain bullet is no joke, and I\u2019ve got a lot of experience in subsonic hunting with a different, but similar caliber. And supersonic ballistics greatly extend the effective range of this platform when needed.<\/p>\n

This pistol is everything you\u2019ve come to know a high-quality AR to be, with billet 7075 aluminum upper and lower construction, precision manufacturing, and stylish design. The lower even comes with a buffer retainer pin and spring installed, for convenient and easy swaps to semi-auto uppers with the simple addition of a buffer and spring to the lower. You can also run the bolt action upper on a lower with buffer and spring installed, but it\u2019ll feel different during operation than your typical bolt action. Speaking of bolt action feel, the UP-10 bolt runs smoothly. There is even a detent in the upper receiver that interacts with the bolt, making its operation feel positive and firm. You\u2019ll find another detent in the lower receiver that puts pressure on the rear pivot pin lug, removing any play between the upper and lower receiver.<\/p>\n

Without any accessories mounted, I weighed my 12.5\u2033 UP-10 in 8.6 Blackout, and it came out to 7 pounds, 4.7 ounces. I have the upper and lower separated to make weighing the gun easier.<\/figcaption><\/figure>\n

Real World: From Truck Gun to Quiet Hunter<\/strong><\/h2>\n

I mentioned this earlier, but I\u2019ve had this UP-10 in 8.6 Blackout for about two years now. I\u2019ve taken it hunting several times, and I\u2019ve taken game animals with it. I really like the versatility of the 8.6 Blackout because I\u2019m able to carry supersonic and subsonic ammunition with me and decide which I want to use for any presented opportunity. I typically carry a supersonic round ready to go, and I\u2019ll put a few subs in my pocket or as my second bullet in the magazine.<\/p>\n

Be aware that you will want to zero your gun for one ammunition or the other. Say you zero your gun for supersonic ammunition, you\u2019ll also want to test the subsonic ammunition to see what your adjustment needs to be for its zero. For example, I sighted in this gun with Aitken Arms 220 grain Maker TREX Supers, but I know that my zero for the Discreet Ballistics 280 grain Selous Expander ammunition is 9 MOA up and 3 MOA left. To make a 100-yard shot with this quiet, hard-hitting, subsonic expanding round, I just need to dial this in the scope and take the shot.<\/p>\n

\"Hunter
Here is a turkey I killed using Discreet Ballistics Selous Expanders. A 50-yard shot was a piece of cake with this quiet, devastating hunting ammunition.<\/figcaption><\/figure>\n

I killed a turkey last fall with the UP-10 using the Discreet Ballistics 280-grain Selous Expander ammunition, and it performed splendidly. This setup is so quiet that I will never forget how loud the impact of the bullet was when compared to the sound of the shot itself. And the terminal performance? It looked like a broadhead had passed through this turkey because the Selous Expander opened up so wide. Of course, it was a full pass-through.<\/p>\n

Another reason I like hunting with the UP-10 is that the manual of arms is very familiar. I work and play a lot with AR-style rifles, and this gun looks and feels the same. With the exception that it\u2019s bolt action, of course. Also, mounting accessories on the handguard is easy because of the full-length MLOK design. You can easily throw on bipods, accessory rails, clip-on thermal or night vision<\/a>, laser designators, and much more to perfectly outfit this gun for your needs. If you aren\u2019t an AR person, maybe the UP-10 won\u2019t be attractive to you. If you are an AR person, I\u2019m sure you are seeing the versatility here. Oh, and if you want a semi-auto for any reason, just throw a semi-auto upper on and go waste a bunch of ammo!<\/p>\n

Accuracy Testing: Subsonic Reality, Supersonic Wins<\/strong><\/h2>\n

For this accuracy test, I removed the suppressor from the UP-10 just to eliminate any potentially confounding variables. I also shot off a bench, using a bipod (Ckye Pod) up front and a rear bag to keep the gun stable. The barrel was allowed to cool fully between shot strings.<\/p>\n

Most of the ammunition I tested is subsonic, probably because this is the main appeal of the 8.6 Blackout cartridge to me. I shot 3-round groups at both 50 and 100 yards, partly because the zero for each ammunition type was wildly different. I used the 50-yard group to get a closer zero for the 100-yard grouping. This inconsistency between ammo types also foreshadowed the general inconsistency that I saw with subsonic ammunition. In some instances, the 100-yard group measured less in MOA than the same ammunition grouped at 50 yards.<\/p>\n

\"UP-10
At the range, I used a bipod and rear bag to keep things stable for accuracy testing.<\/figcaption><\/figure>\n

The ammunition I used was provided by the manufacturers, for the most part. This included Discreet Ballistics<\/a> 280 grain Selous Machined Expanders, Mead 250 grain FMJ<\/a>, and three different subsonic and supersonic offerings from Aitken Arms<\/a>. I also grabbed some Fort Scott Munitions 285-grain TUI from Ammotogo.com<\/a>.<\/p>\n

\"UP-10<\/source><\/picture>
These are the results of the 50-yard accuracy testing. Take note of how well the 220 grain TREX super from Aitken Arms (bottom right) performed! The other Aitken Arms ammunition you see in the photo is the 350-grain Maker REX sub (top left) and the 300-grain maker Solid.<\/figcaption><\/figure>\n
\"UP-10<\/source><\/picture>
These are the results of the 100-yard accuracy test. This time, you\u2019ll find the Aitken Arms 350 grain Maker REX subs on the top left, 300 grain Maker Solids on the top right, and 220 grain Maker TREX supers in the middle left on the separate sheet of paper. The rest of the groups should be easy to identify by the boxes next to them.<\/figcaption><\/figure>\n

As you can see, the UP-10 shot the supersonic ammunition the best, which is not surprising to me. It kept the Aitken Arms 220-grain Maker TREX Super ammunition grouping at or under 1 MOA, which is what Uintah Precision guarantees their rifles to shoot. The rest of the ammunition I tested is more novelty or special use. Still, the Mead 250-grain FMJ subsonic ammunition hovered near the 1 MOA mark.<\/p>\n

Some of you may see that a few popular, expensive subsonic options shot pretty poorly and get upset. I would warn you that with subsonic ammunition, nothing is predictable. You may have to try many different bullets to find one that performs well in any given rifle, and I think that is illustrated here. If I were to hunt with the UP-10 beyond 100 yards, I would want to test other subsonic ammunition until I found one that performed as needed, and I have no doubt that I\u2019d find this combo.<\/p>\n

The 12.5\u2033 barrel and 12\u2033 handguard pair well with a suppressor, creating the smallest gap between the end of the handguard and the back of the suppressor when it\u2019s attached.<\/figcaption><\/figure>\n
