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.

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: The one in front, but u will need to loosen the side screw first because that screw LOCKS the front screw so it won't come loose.
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.
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"

Glen from Wisconsin
Will this upper attach to my 223 AR -15 colt with no "fit" issues ?
Jay 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
What it the side screw on the gas block for??
Karl R on Oct 17, 2018
BEST ANSWER: Locks adjustment screw(accessed from muzzle end of block) in place, to preclude it working loose under recoil.
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 size is the thread and will it work with a 223 or 556 muzzle break?
Charlie L on Oct 25, 2018
BEST ANSWER: 1/2 x 28
Is this a complete upper?
Matt B on Oct 21, 2018
BEST ANSWER: yes, read the description
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.

.224 20 inch Valkyrie upper, on a Aero Precision lower, with a AT3 2 stage trigger
I am very please with this upper. Over 300 rounds fired and no notable problems. 100 yard zero yield pin point results on a 6 inch target. I will extend range next visit to range. I highly recommend it.

Glad I bought this!!
The upper was even nicer than I thought it would be upon delivery. After break in and sighting in the thing shoots 3/4” groups with the 90gr fusion ammo. Unreal for the price. It is just getting to fur season here in ND and the first coyote I shot dropped like I turned the switch off!! I’m pressure round!!

Great Upper for the Price
Bought mine and mated it to an Anderson lower with a Geissele trigger. They say a picture is worth a thousand words. This was with 90 Federal Match, shot at 100 yards. The upper group is the fist four shots, followed by the second four shots below it (after a minor adjustment). No complaints with the gun for what I have in it.

Very happy with PSA
Bought this quality upper on clearance and after a couple of hundred rounds has worked flawlessly. Have been happy enough with it that it deserved the investment of dedicated lower with a Geissele trigger group.

Pretty good but a little high priced.
I can get a 22" one with a SS HBAR for less money and no shipping so I am not buying more at this price But there is nothing wrong with this one! I is smooth and a real tack driver.
