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" Lightweight 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.

Is there any kind of MOA accuracy guarantee on this barrel?
JoelVang on Jun 7, 2018
BEST ANSWER: If only capable of a 3" MOA, then this assy makes no sense in being touted as a long range "tack driver". My .270 groups way better than that.
What type of rifling does your 224 Valkyrie barrel have? 5R rifling?
larry d on Jul 6, 2018
Do you have a 224 Valkyrie upper kit unassembled ?
Bigabe41 on May 18, 2018
BEST ANSWER: The 224 Valkyrie upper is designed to function with any Mil-Spec AR-15 Lower Receiver and is to be used with a standard 6.8 SPC Magazine.
will this also fire a .223 or no?
Ben S. on Jun 8, 2018
does this upper fire 5.56, .223, and .224? or just .224?
Ben S. on Jun 8, 2018
BEST ANSWER: Just 224 Valkyrie
Does it come with the bolt assembly?
Chuck on Jun 24, 2018
BEST ANSWER: Yes, BCG stands for Bolt Carrier Group and CH stands for Charging Handle...
Is the muzzle brake removable? If so what is the thread spec?
David S on Jun 20, 2018
BEST ANSWER: It is removable with the right tools, and the thread pitch is 1/2x28.
What size buffer is recommended to go with this? Just a standard rifle buffer tube and spring?
Shane T on Aug 12, 2018
BEST ANSWER: The standard rifle buffer works fine with ejection at 3;30 on this 20 inch 224 Valkyrie!!
Do I just remove the 223 upper and replace with the .224 upper?? Are there any mods that have to be done other than that??
Richard D on Sep 2, 2018
BEST ANSWER: Yes, the .224 Valkyrie will fit on a mil-spec ar15 lower... however, you will need to use 6.8 spc mags for the Valkyrie, which will fit into an ar15 lower. Haven't need anything else!
Is there a way to get a barrell that has a 1moa or 2 MOA guarentee?
Bill H on Nov 9, 2018
BEST ANSWER: Pay a lot more.
Will this upper fit an old style Bushmaster?
Jeff B on Jun 26, 2018
BEST ANSWER: This upper fits Mil-Spec lowers. If your Bushy is Mil (and I'm pretty sure it is), you'll be ok.

shoots pretty well
I have 2x PSA .224 1/7 barrel/upper setups. One I bedded into an Aero enhanced upper, and one that was a PSA assembled item. Both shoot about the same. Shoots the cheap Federal 75gr FMJ about 1ish MOA, and is accurate to 400yards+++(limit of my range :(). It will shoot 90gr Federal fusion at <1MOA 4 out of 5 shots, then get a flier to open the group to about 1.5MOA. Where I have issues is hand loads. My 75gr/80gr Hornady ELD Match bullets seem to do ok. But my 88gr Hornady ELD Matches I can't get to hold good groups. It may be more fiddling on my part needed, but I worry about the early barrels having excessive free bore. I bought 2x 20" PSA 6.5 twist barrels to compare. Overall, I'm super happy. For what I need, these shoot great and were affordable. I hope to get to some family farm land this year to test out 1,000 yard shots ;).

PSA 20" Rifle-Length .224 Valkyrie 1/7 Stainless Steel 15" Lightweight M-Lok Upper with BCG & CH - 5165448419
This mounted on my M&P lower with precision. It shot under 1"groups at 50 yards with 55 gr. - 80 gr. I am well pleased with the hookup......Bob

Great price solid upper!
I ordered the complete upper and when it arrived I popped the pins on my 223 and in about 2 minutes I was adjusting my sights on target. It went together slick and the 6.8 spc Mags I purchased worked flawlessly. It shot 1.5 inch groups with magpul battle sights off my bench using generic Federal ammo. I am very pleased with this upper and I bought one for a friend he put it on a Remington R15 without issue and it groups about the same. I would recommend this upper without hesitation.

Works with factory ammo. Needs more gas for my hand loads.
Works great with factory ammo.  Don't want to cycle correctly with my hand loads. Gotta up the gas.
