UPR-15 UPPER

Took a while and this story is is worth telling maybe room on FB but thi is an awesome product my Valkyrie build started life as a Savage AR in Valkyrie that did not impress me . I visited these guys last year and to say they were gracious is an understatement I broke my sisters boat trailer in their yard and they fixed it – I was on my way to Florida from Oregon – I ordered an upper and when it arrived i was moving and had no time to invest at the range . When the time happened I took a few assembled hand loads and some factory match.
The handloads shot ok not what I was looking for so I tried the Hornady 88 gr factory load not tight groups but consistently at or under the MOA PROMISE . Truncated timetable I shot in an F CLASS match with some very hard holders and whereas I did not win the match – most were shooting dedicated match rifles – the rifle performed admirably holding less than MOA horizontally with some uncalled vertical stringing at MOA . Bottom line I will get another it is awesome and accurate, I see a 6 mm arc in my future

Tested the UPR-15, 223 Wilde, 20-inch today. First 4 shots at 50 yards easily yielded 0.5″ group; verifying the 1 MOA guarantee. This was casual, bench-rest plinking with common everyday 55g reloads. With more careful aiming and optimized ammo, I expect even better! The rear take-down pin was tight on the Aero Precision lower and required a few taps from a soft mallet. Removing it also required a few taps with a flat punch. This is by design, according to Uintah; the tight upper-to-lower fit ensures maximum precision, which is what I want. I’m pleased with this initial test and look forward to more serious precision testing.

I purchased the UPR 15 in .223 Wylde. Zero’d at 100 yds. Six shot group was was cover by a quarter. Super pleased. Great quality upper.

Got a 223 Wylde upper earlier this year and installed on a milspec lower – very nice fit and trigger installed perfectly. Broke barrel in as per instructions and after roughly 100 rds, proceeded to shoot 5 shot 1/4 moa 100 yd groups with both my 69 SMK and 77 SMK generic handloads. Subsequent range trips have been just as successful. looking fwd to breaking in my 300 BO upper soon and seeing what it will do.

I bought a U/P upper in 6mm ARC. I went to the range yesterday. After sighting in the scope, I shot a 7-shot group at 100 yards that I could cover with my thumb. All seven shots were touching one or more holes from another shot. I was shooting Hornady 105 gr. Black ammo. Super pleased with the bolt action upper! Can’t wait to get it out at long range and show my son that his Desert Tech is not the only accurate rifle.

Update review
I bought a 6.5 Grendel upper for wife for Christmas. After about 120 rounds of different hand loads we came up with the perfect load. She was able shoot a 3 shot group at 100 yards that measured .311 by .183 inches.
the was Hornady 123 gr SST bullet, 28.5 gr of Accurate 2520 with CCI 450 primers.
She is SUPER happy with this upper.
Thank you Uintah for making high Quality products…
I think she posted a picture of her target on instagram.

I have a 224 Valkyrie upper purchased from Uintah Precision. Nothing remarkable about my lower except the recommended Jard top adjustable with the speed hammer about 1 1/2 lb pull. After the first hundred rounds I’m shooting well into 1/2 moa at 100yds and I shot Wed the 13th and at 200yds had a group that measured .732 center to center. Brass ejects with authority, zero FTE’s, zero feed issues and zero FTF. Haven’t gone past 400yds yet but I have no worries. After the first 50 rounds or so I called in a custom order for a 6mm ARC 26″ heavy profile, with no worries. Absolutely lived up to the 1 MOA claim then some. I have had several Q&A with Mr Baker on the phone who seemed ready to answer all my nervous questions. I say buy with confidence. You do your part, and the rifle will do it’s part.

1 year update. My wife’s 6.5 Grendel upper is consistently grouping .5 inches at 100 yards with her hand loads. One of her favorite loads is Hornady 95gn V-Max 29.5 grains A2520 CCI 450 primers trim length 1 510 COL 2.240.

Been contemplating ordering this Uintah Precision 20 inch 223 Wylde Upper for almost 6 months. Finally, made a decision to pull the trigger. Uintah Precision has exceeded my expectation. This upper is very accurate and feeds without a hitch. This upper loves 69 or 77 grain bullets in my experience. Shot .75 to .50 inch, 5 shot groupings using my already proven semi-auto loads. More than likely do better once I tweak the loads a little. Being the way ammo prices and supply are up and down. This upper is saving me ammo. I am taking more time to chamber, aim and focus on every shot. Wish I had bought this earlier. Don’t get me wrong, I still love my semi-autos but this is a great addition to my training. Awesome Job, Uintah !! and Great Customer Service !!

My UPR15 in 6.5 Grendel arrived as promised. It was well packaged and the quality was apparent. After following the recommended break in procedure, the next 5-round 100yd. group through a freshly cleaned, cold barrel measured just over an inch. With the barrel warmed and “seasoned” with just 5 shots, the following 5-round group measured 0.733 with 4 of the five touching and one “flier” which took the group from 0.450 to 0.733. The flyer was no doubt my shooting and not the barrel. I couldn’t be more pleased. Customer service was excellent and the UPR15 easily meets the sub MOA guarantee. Thanks Uintah!

I bought a UPR 15 in 6 ARC with the 16 inch barrel with the intention of shooting lighter bullets.
After some trial and error it settled in on Benchmark powder and Barnes 62 grain varmint grenades. Turned in a .187 group today. Looking forward to going after coyotes with it.

I recently purchased the 223 Wylde upper with a 16″ barrel, and I am extremely satisfied with its performance. The upper has a premium feel, and the action is smooth, providing a seamless shooting experience. What sets it apart is that the action is similar to a traditional bolt action, but with some noticeable improvements that make it even better, in my opinion.

One of the standout features of this upper is its accuracy. The barrel performs consistently well, allowing for precise shots downrange. I found that for long-distance shooting, using match or heavier grain ammo further improved the accuracy, delivering impressive results on the target.

The clean, simple, and minimalist design of this upper is another aspect that I love. It’s a real head-turner at the range, and many people were surprised to learn that bolt action uppers are available for ARs. The combination of sleek aesthetics and reliable performance makes this upper a real standout in terms of both form and function.

The versatility of the 223 Wylde chamber is also worth noting. Being able to shoot both .223 Remington and 5.56 NATO ammo provides me with more options and flexibility for different shooting scenarios.

In conclusion, I am thrilled with my purchase of the 223 Wylde upper with a 16″ barrel. Its premium feel, smooth action, and accurate performance make it a top choice for long-distance shooting. The clean and minimalist design adds a touch of style, making it a standout at the range. I highly recommend this upper to anyone looking for a reliable and high-performing option for their AR build.

I first must apologize to customer support for not reading the whole description fully. I was very excited to get this and try it out.
That being said, I want to say my anticipation was well deserved. This upper performed so much better the semi-auto when it came to accuracy and grouping. After a few shots to zero it in. I was hitting the same areas multiple time so tight you could barely see the center target from 100 yards.
I am so happy with this upper, makes my AR a precision rifle. With a classic bolt action feel, low recoil and a crazy MOA! I appreciate you product and would recommend.

UPR15 22 ARC 20 inch barrel. If you’re worried about how the action operates, don’t, it’s slick! Uintah nailed it! The bolt even locks back after the last round. Nice they kept this feature from the AR, no more throwing the bolt forward just to hear a click! My only complaint is be careful when attaching Mlok accessories the screws maybe too long and make contact with the barrel. I’m assuming since there is no gas tube the hand guard is smaller diameter which does feel nice and probably saves weight. I’m not a “PRS” shooter. I do an awful lot of varmint hunting and consider myself a better than average shooter. I have never shot a group like this! And with factory Hornady Match 88’s. I’m really looking forward to hand loads!

This upper is absolutely amazing in all fronts. Extremely accurate and smooth. Well built, solid construction.

Once I got the barrel broken in, 1/2moa 10 shot groups become disappointing as the rifle is definitely capable of more. It also allows me to hunt with, my very familiar, AR15 lower in my state. That wasn’t the main reason for my purchase, but it was definitely a nice “feature” for me.
