Uintah Precision

These look great, random question and I don't mean to hijack a thread but as a Californian, would swapping this onto an AR make it a "bolt rifle" in the eyes of the law?
 
Has anyone heard of them and what can you tell me?

I have one of their uppers in .224 Valkyrie. The only problems that I have had have been with the magazines; which they do not make.

The first ones that I got were the E-lander magazines in the 10 round configuration. It was stiffer than a witch's you-no-what. I used the magazine tool from MPA to spread the feed lips out and that solved the problem.

Then I got the AR-Stoner magazines with the 15 round capacity. I had the same feeding problems and spread the feed lips out on them and it solved the problem. However, I could not get more than 10 rounds in the 15 round magazine because it would cause the first five rounds to tip down and causing the bullet to jam against the feed ramp.

I am thinking about getting PRI or E-lander magazines in the 15/17 round capacity. If you compare them to the AR-Stoner mags you will note a slight curve. The AR-Stoner is straight. I am hoping the slight curve keeps the rounds from tipping down when I load the magazine to full capacity.

The first photo is the 15 round Stoner. The second photo is the PRI 15 round magazine. The third one is the E-lander 17 round magazine. Notice the slight curve in the PRI and E-Lander.

The AR-Stoner magazines work fine if you spread the feed lips out on them as well.

I will note that when spreading the feed lips out, you want to do so by creating a slightly wider spread toward the front of the magazine. This allows the cartridge to tip up slightly so the bullet does not jam against the feed ramp. Go slow when you modify the magazines and practice chambering the rounds.

As far as accuracy is concerned, I don't like to bench my rifles when zeroing them in unless someone else is at the range and I have no other choice.

I zero the rifle with the bipod in the dirt like I would shoot it the majority of time in the field. I also shoot 10 round groups with the barrel warming up to duplicate real-world situations for competition or target rich environments.

That being said, I get 3/4 MOA groups on my worst day with a ten shot group using the Hornady factory 88 grain ELD match loads.

I'm not as good as the guys shooting the 6.5 CM, 6.5 X 47L or the 6mm CM but hitting a 24" plate of steel at 1,000 yards is pretty darn easy. Attached is the ballistics from JBM for my rifle. The 16 inch plate at 1,000 yards isn't too bad until the wind picks up. So far the smallest plate that I could hit with some consistency when conditions were good is the 8 inch plate but I have to work at it.

I don't reload for it as I've found the Hornady factory loads for the rifle to be great. I purchased a gazillion rounds from Target Sports USA and SGAmmo when it was on sale. After the 6,500 I have are shot up, I'll get a new barrel.

I might add that I also shoot the rifle suppressed. I was shooting with a gentleman who had a gas gun in .224 Valkyrie in 88 ELD factory loads.

After about 5 rounds at 1,000 yards the corsshairs start dancing in the scope due to the heat from the suppressor. That made it more difficult for me to put rounds on the target. The other guy was shooting without a muzzle brake on his gas gun and hitting steel more than me.

I also suspect that the hot suppressor caused me some problems when I zeroed the weapon.

Since that time, I've obtained a suppressor wrap which cut down on the dancing crosshairs. I have not had a chance to evaluate the groups after wrapping the suppressor but have been hitting steel more often at distance than I did before. That tells me that my groups may have shrunk a little with the use of the wrap.

BTW, they were nice enough to give me a veteran's discount. Call them for that.

The Uintah is on the right. I don't regret my purchase and it is one of my favorite rifles to shoot.

That’s
The 6.5 Grendel that I tested did not shoot well. I ran almost every factory load known and some hand loads. None of them shot less than one inch at 100.
I sent it back.
weird, I have a 6.5 creed and a 224 Valkyrie from them.
everyone that I know that has one also says they shoot lights out. Both my guns are Half moa. Was yours like a loaner gun? Wonder if someone fucked up the crown or something.
 
I have one in 6mm ARC, it is a tack driver. They use barrels from Preferred Barrel Blank, they are a subsidiary of Match Grade Barrels. These are top notch match grade barrels. Mine shoots .50 to .75 MOA easily. After I got it broke in I sent the barrel and bolt to H&M to have them Nitrided. Buy with confidence.

Would anyone put these in the same category of a “real” bolt rifle (T3/Howa/Zermatt/etc)?

Basically, a 6.5CM upper on an Aero large frame lower would be pretty nice. AR ergos with a bolt.
 
Have you had issues feeding from the mag on 6 ARC ? I’m using duramags and if I single feed it shoots moa. Throw rounds in a mag and it goes to crap
 
Regardless of how you perceive what a bolt action is, the Uintah is a bolt action. You have to manually operate the bolt to load and eject the round using a bolt action. It is just a different approach to what is commonly accepted as a bolt action rifle. It uses bolt gun loads, about 10,000 PSI higher pressures over the gas gun counter part. Is it the smoothest bolt action out there.. No it is not, but it gets the job done without issue. Is it accurate... Yes it is as accurate as any other bolt action in it's class, mine shoots .5 or less MOA all day long with hand loads. It is also very easy to work on and most of the parts are commonly availabe that are shared with an AR15, which is probably the most common rifle ever made.

I have 3 of these UPRs, they are just as accurate as any of my other bolt guns. You are just limited by the mags they accept if you are running a long COAL on your reloads. But the lock time, has never affected my groups. I can tell you it handles pressure better than any rifle I have ever loaded for, and my 6.5 cm achieved higher velocities than any 6.5 cm I have ever heard or seen of on the internet with a 150gr class projectile. No accuracy issues all the way out to 2500 yards. The bolt-on my upr10s run smoother than my upgraded r700 actions, however, the bolt-on myupr15 is not as smooth. One thing about the upr10s is I know they use to run large diameter firing pin, I had them make me one with a small diameter firing pin which allowed me to get the above crazy velocities, otherwise, it was piercing primers from primer flow. However others I know have not had that same issue when running high velocities. It's definitely one of my favorite rifles and I will never sell them. Anyone saying its not a "Real bolt action" is quite silly. It is, however it may not have the traditional bolt action mechanics we are used to. Either way I give them kudos for bringing a new type of product to the market like this. They really are great, fun to shoot and very high quality.

Alexander Arms 6.5 Grendel mags should solve feeding problems according to literature I've read , I plan on purchasing one soon and a semi-auto upper in 6mm ARC from ? when America realizes the mistake it made regarding Brandon!
Should be a great coyote RX!
 
Would love to see a head to head between one of these and a sig cross and Q fix.
The Fix probably has them both in fit and finish but I would love to see an accuracy shoot out.
 
Well, one of them has a slap hammer and take down pins so it’s not really fair…
Some AR’s are quite accurate even with their trigger limitations. It seems all three guns are a cross (no pun intended) between a traditional bolt rifle and an Ar platform where the chassis and receiver are one and the same.
In inherent accuracy between each should be similar imho but I haven’t shot any of them.
 
Yeah, they look similar… Only God knows how that would turn out…

Anywho, I’m gonna dip, fellas. Gonna grab a pumpkin spice and talk politics in the ESPN comments. Later.
 
I've had my upr for all most a year .wanted to use it in last year's deer season but it did not make it in time . had it made in 708 22''cost a little more yet it was worth it . contemplated having a 284 win barrel made
