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.

Other than weight, is there any difference between the lightweight upper and the standard upper?
Jsand on Sep 8, 2018
BEST ANSWER: have both, the only physical difference is the design of the 15 inch handguards.
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
Would you be able to use your 2.23/5.56 lower assembly, just change the magazines for 6.8!!??
William H on Oct 8, 2018
BEST ANSWER: Yes, that is correct, that is what I did, I put this upper on my .223 lower and bought 6.8 mags, which can be expensive. You are getting this upper at a great price right now. I wish I had waited.
Does this upper come with a rail to attach a front grip/bipod?
ThebigOshow on Oct 12, 2018
BEST ANSWER: No it does not come with a rail to attach a bi-pod. However it has a M-LOK handguard and there are lots of aftermarket add ons that you will find for the M-Lok. Start looking right here at P.S.A.

I liked the upper I bought so much I bought a second one! "MORE IS BETTER"

Are there any QD sling holes on the rail?
Tony on Jun 19, 2018
BEST ANSWER: Johnny S, there are no QD slots integrated on the mlok rail. Easy to add though. See attached.

What it the side screw on the gas block for??
Karl R on Oct 17, 2018
BEST ANSWER: That is to adjust the gas. Best thing to do is turn it all the way in that will shut off the gas fire a round and bolt should not cycle. Then back it out 1 -1/12 turns at a time till the bolt will cycle and hold open on and empty mag. Then turn it about half a turn more that will allow the gun to operate the best. Mine is set at about 3 1/2 turns
Is this bolt carrier group the exact same as a regular AR15 bolt carrier group?
Kkelly on Oct 6, 2018
BEST ANSWER: the Valkyrie uses a 6.8 SPC bolt carrier group.

Some issues, but very accurate
The 1st time I took it out, I shot a sub 1 inch group, then the bolt jammed. It appeared the gas key mangled the end of the gas tube & got stuck on it. I sent it in for repairs. I took the repaired upper out & shot sub inch groups with Fed 75 grain ammo. It functions fine, but there May be another issue. I tried reloading some of my once fired brass, and every reload stuck in the chamber. I checked the once fired cases with a L.E. Wilson case gauge & the shoulders are blown out 10 thousandths, which make them out of headspace spec. New brass & factory ammo work fine. My Lee & RCBS dies don’t bump the shoulder.

20” PSA .224 Valkyrie upper
I saw this upper on sale and had to get it. It was a great purchase. Put a 40mm Nikon Prostaff 5 3.5 x 14 scope on it. We had it sighted in, in 5 shots. Shooting cheap American Eagle ammo it was getting less than 3/4” groups at 100 yards. In my 10 shot group with Hornady ELD Match, 5 shots were on top of each other, the other 5 were within a 1/2”. No issues at all with feeding, cycling, or anything. The upper ran flawless with my lower. This was a great purchase, I’d recommend it to anyone.
10 shot group, 2 flyers, 5 shots touching

Great Upper and Great Value!!!
I ordered this upper and have been extremely satisfied. The accuracy has been great at distances from 50 to 300 yds. I used a lower that I already had from a locally manufactured 300 blk, and not had a single issue with feeding and overall operation. I have since ordered a PSA Magpul lower and will be testing this combo out soon. My upper was sold as a blem, but I could not find any issues with it. I am not the greatest marksman by any means, but would highly recommend this for both accuracy and reliability.

Yes- - it shoots really well!
I have just completed my first and second rounds of powder, bullet, and COAL testing. I am very pleased with the results so far. I found (yes, unexpected) 1" groups at my targets. Some where a little under. Some a little more, depending on powder charge. OK - - I am hooked. No, wait, maybe I should say the groups were poor so no one else will purchase Valkyrie supplies I now need...! Thanks for a great product, definitely worth the price.

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.
