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 Smith 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.
Is this a complete upper?
Matt B on Oct 21, 2018
BEST ANSWER: yes, read the description
Are there any QD sling holes on the rail?
Tony on Jun 19, 2018

Why don't you have a 22" and 24" barrel for this long range cartridge?
Ray P on Jan 3, 2019
BEST ANSWER: I've shot this upper out to 1000 yards with no problems. Haven't yet shot it over 1000 yards but I don't see an there being an issue with the 20" barrel. Thank you Rod.
What size is the thread and will it work with a 223 or 556 muzzle break?
Charlie L on Oct 25, 2018
BEST ANSWER: Standard 22 cal 1/2" x 28 TPI
We want multiple uppers. Why not do a special run of 6.5" rifling 24" barreled uppers for 90 gr. Bullets?
Ray P on Jan 3, 2019
BEST ANSWER: I have been very happy with my 224 . It's a great shooter.

PSA 20" Rifle-Length .224 Valkyrie 1/7 Stainless Steel 15" M-Lok Upper with BCG & CH
224 Valkyrie is just fun. I've not tried 1,000 yards because there's better options! But knowing the round is heavier and faster than 5.56 makes it fun. My personal "practical" accuracy has been MOA at less than 200 yards. Try a milk jug challenge at 100 yards against a 556 and you'll see the difference. Do a thorough barrel break in process. I also used a wore out .22 wire barrel brush with polishing compound and my results have been better than most. 1/2x28 also allows you to use your 556 suppressor! That's a bonus.

Good price point
Good value. After barrel break-in, it seems fairy accurate with commercial 75 grain ammo. Probably less than 2 MOA, shot at three hundred yards. Once I get some time to work up a load, it should be less than half that. I believe this upper has potential for being sub MOA.

Handguard is a nice fit.

Excellent Value
At a $300 price point I cant complain. This may not be as aesthetic as a $1,000 of the rack production but it will give you excellent accuracy and decent weight/ ergonomics. Out of the box I am getting 1 inch groups with factory ammo.

Excellent deal for this quality completed upper
I was quite pleased with the accuracy of this platform, shooting Federal 75 Gr TMJ which is the cheapest per box option produces sub MOA accuracy. The fit and finish of the product is excellent, can't ask for more considering what I paid for this completed upper. I've purchased several products from PSA over the years, this is by far one of my best purchases.

sweet gun.
Love it. Shooting inch groups out of the box with factory ammo. Can’t wait to get it broke in and start playing with different loads and extend my range.

The upper operates very well, as expected. Shoots as expected, very, very good.

Excellent Value
The price for this hardware was unbeatable. The blemish was practically microscopic. I have 14 rounds of 75 grain Federal through it for barrel break-in it but only open sights. I have a 4-16 power scope to mount and sight in so I will then determine the accuracy which I expect to be very good. I have read about the 1:6.5 twist. I am curious if that helps stabilize the 90 grain Match Kings.
