The .224 Valkyrie fills a gap in the AR ecosystem of 22 calibers. Ammunition for the 22 consisted of cartridges such as the 556 and Nosler; however, these cut around 600 to 700 yards without the proper velocity. Federal Premiums created the .224 Valkyrie to remain at supersonic speed for downrange accuracy.
.224 Valkyrie guarantees supersonic speed at 1300 yards. This achievement marks the first cartridge for the MSR-15 platform to achieve that velocity.
This article tells shooters what to look for in quality Upper Receivers for the AR-15 platform. No other ecosystem is as broad and varied as the AR. Every element of the AR, no matter the caliber, can be upgraded or changed out to customize the rifle to exactly what the shooter needs.

Elements of an AR-15 .224 Upper Receiver
Receiver parts are simple, but all play a vital role in accuracy. AR-15 receivers are not manufactured the same; some parts are crafted with only minimum standards. Let’s look at the seven components that make up a quality upper receiver.
- High-quality Barrels give the shooter their best shot at accuracy in long-distance situations. The barrel twist ratio is significant when choosing your distance. .224 Valkyrie is known to have excellent down-range characteristics; It is better to choose a barrel length of 20 inches or more if long-range accuracy is your goal.
- Gas Systems in the AR-15 improve the overall function of the rifle. There are four lengths to choose from, carbine, pistol, mid, and rifle-like. Gas systems and barrel length work together to improve functioning and accuracy.
- The Bolt Carrier Group ensures the AR fires and ejects each and every round as designed. Within the BCG is a firing pin, cam pin, gas key, and extractor. The BCG consumes the power of a fired round and bolts backward; this process facilitates the ejection of the round.
- A Forward Assist is considered by many purists to be strictly ornamental these days. This component is added to the bolt in the chance of a jam or cartridge getting stuck.
- AR-15 Charging Handles connect to the BCG to help with smooth functionality. The charging handle pulls the BCG back to the chamber and can be used to troubleshoot. When working correctly, the charging handle improves bolt function.
- Ejection Port Covers or dust covers are some of the easiest and essential parts you can add to the AR-15. Port covers keep the dust and grime out of the most critical area of your rifle and keeps the firearm working as it should. Port covers have become more than just smooth aluminum plates; they have been transformed into signature parts with custom designs.
- Rail System and Handguards have turned into an essential piece of equipment with thousands of rounds shot through the rifles. Rail Guards protect the shooter from a hot barrel.
