Add To:

The ultimate long range AR-15 upper is finally here!

The 224 Valkyrie round was developed to bring unheard of accuracy and long range ballistic performance to the AR-15 platform. 

Barrel: The PSA 224 Valkyrie upper receiver was created with a 416R Stainless Steel barrel with a 1:7 twist rate for optimal accuracy over long distances.  Cycling reliability is achieved with a rifle length gas system, which is completed with a PSA Low-profile adjustable Gas Block.  The barrel is finished off with an A2 flash hider and a PSA 15" M-Lok Rail.  

Upper Receiver: The forged 7075-T6 A3 AR upper is machined to MIL-SPECS and hard coat anodized. These uppers are made for us right here in the USA by a mil-spec manufacturer.

On the gas block there are 2 screws one on the front and one on the right side! Which one do you use to adjust the gas?
D-Lay on May 11, 2018
BEST ANSWER: You use the front screw
Is a 224 Valkyrie lower the same as a regular 5.56 or .223 lower?
Mike on Jun 4, 2018
BEST ANSWER: Yes, they both use the AR-15 lower. However the 224 Valkyrie cartridge will not work with a 5.56/223 magazine. You have to use a 6.8 spc magazine. Diameter of 224 Valkyrie is larger than the 5.56/223.
Will this upper attach to my 223 AR -15 colt with no "fit" issues ?
Hitman on May 2, 2018
BEST ANSWER: This upper fit 4 different lowers I had. They were all nil spec lowers from PSA, Spikes, BCM and smith and Wesson. It should fit your colt lower as long as it is a standard AR-15 mil spec lower
Are there any QD sling holes on the rail?
Johnny S on Jun 19, 2018
BEST ANSWER: there are no sling holes per say. it is the m-lok system and many manufacturers make adapters for the system to mount just about anything that you wish to install. shop around and you will find what you are looking for. I installed an adapter to mount my bipod which then also gave me a mount for a sling if i wanted to mount one. Glen / Wisconsin
Other than weight, is there any difference between the lightweight upper and the standard upper?

Not a bad upper
Upper looks really good, it is not shooting the factory ammo that well, not sure if the 1:7 twist was baked well enough now that they have 1:6.5 twist barrels out there. Time will tell, also they dropped the price after I bought mine, so not so happy about that either.

Great upper but....
Excellent quality. I’m only giving it 4 stars because sometimes I get an initial round that jams when I load it. It might be the magazine I’m using but I haven’t tried another yet so I don’t know yet. When I do I will update my rating to 5 stars.

Will not group very well
This upper will not group better than 3.5 inches with the Federal 90 grain match ammo. I shot the fusion 90 grain and it was worse. Once my reloading dies get here I will try lighter bullets. The fit, finish and operation of the upper is great. Just no accuracy. I am very disappointed right now. Shooting with a bipod and rear bag with very good optics. The groups are consistent, leading me to believe the 1:7 twist will not stabilize the 90 grain bullet. I have several .224 caliber rifles that will shoot circles around this one. I hope I can salvage the upper with loading lighter bullets. Not happy so far because the main reason I got it was due to the fact it was represented as a 90 grain bullet shooter.

Chronographed at 2600 fps, which is great. But not very accurate yet. About 2.5" at 100 yards. Only about 40 rounds through it so far, hoping that after a couple hundred rounds it will break in and be more accurate.

Very inaccurate while bench resting very disappointed.
Fit and finish are great but accuracy was terrible. I put this on a psa lower and I couldn’t be more disappointed. With American eagle factory ammo 75 grn fmj I couldn’t even get my groups to touch at 25 yards even when I was resting it with a brand new leupold 6 by 18 by 40 mk ar scope. When I stepped out to 100 yards I had over a 20 inch rise from where I was shooting at 25 yards and was unable to hold a consistent group. Very disappointed in the accuracy of this upper. I guess I’ll try a 90 grain bullet next time but so far the 224 isn’t living up to all the hype.

20' psa .224 valkyrie sku 516544785
Had to get something in the NEW caliber...... I made the right choice. What a piece of machinery! Functions perfectly, no problems with anything and amazingly accurate. I would buy it again and again........

Well made
I assembled this upper on a PSA .224 Valkyrie marked lower, with PSA lower parts. I mounted a Leupold Mk4 scope using Leupold 30mm QD rings. Everything looks really great. The only downside is the first 10 rounds of Fed Matchking 90gr ammo grouped into just over 4" at 100 yds, from the bench. My two other AR platform rifles group consistently at .5 to .75 MOA . I plan to clean, check everything and try again. Hoping for improvement.......

pretty accurate
I shot different bullet weights of the federal and both had groups of about one inch. I also shot some of my reloads and it did even better. I really wanted a 24" barrel but settled for the 20". It'l do the job just fine. I would recommend this upper because it works just great. No issues with it, period

Nice shooter, love the heavier bullet
Here it is on a Colt lower. It is a very good fit. Also fit a DDLES, an M1 Machine 80% and of course PSA. Any 'Mil-spec' should do.
