Hardened Arms, LLC is pleased  to bring you the new .224 Valkyrie. The 224 Valkyrie cartridge developed by Federal has been hailed as one of the hottest rounds of the year. Using heavier and longer projectiles than the 5.56/.223, it is capable of greater accuracy and substantially longer distance because of the higher ballistic co-efficient and increased energy carried down range.  The .224 Valkyrie produces velocities in the 2700 to 2900 foot per second range using 75+ grain Federal Valkyrie ammo. This is a 1200 yard capable round out of an H-bar profile barrel.  You won believe the performance you get. Distance shooting just became a lot more fun and much more accessible for AR15 owners. The .224 uses a mil spec AR lower, 6.8 bolt and 5.56 magazine.

At the heart of the Hardened Arms .224 Valkyrie upper/rifles are our Lynx barrels which are machined in-house from 4150CMV US steel. Hardened Arms barrels are nitrogen stress relieved, air gauged bore scoped and chamber checked all through the machining process to give you the most accurate, durable and reliable base to build your long distance .224 Valkyrie AR15 platform with.

Now available in 19.5 lengths, finished  hardcoat Melonite for accuracy and durability you will get years of performance out of your Valkyrie.

4150CMV Barrel Steel
Whether starting with our 4150CMV machine gun barrel steel or highly refined 416R stainless steel our barrels are a cut above the rest. Engineered for accuracy and durability they are double nitrogen stress relieved and sodium nitrate coated/melonited (raw stainless steel is polished with melonited extensions). Index pins that lock into the upper receiver are pinned into the barrel through the extension on melonited barrels meaning the extension will never come loose. Machined in house on state of the art CNC equipment we deliver a barrel with every spec carefully controlled for peak performance.
Rail Lock Free Float Handguard
Machining our handguards in house provides us the opportunity to integrate features not found on most rails in the industry. Our rail lock feature, is designed to dovetail around your upper reciever insexing to insure a perfectly aligned rail that extends over the end of the upper reciever enough to do away with the unsightly gap found on lesser quality rail to receiver match ups. Combined with 6061-T6 aluminum with class II type III, hard coat anodized finish to match our uppers, fit and finish are top notch. Hardened Arms has many rail styles to choose from that are both stylish and functional. Our handguard offerings include quad rails, reduced weight rails, ergonomic smooth rails, skinny competition rails and our innovative patented Lumashark(R) illuminated rail with high lumen lights built in. Hardened Arms rails come in a variety of lengths and choices to meet your mission specific needs. .
Attention to detail.
It's the attention to detail that sets Hardened Arms apart. Items such as our machined in house 'Jam Nut' ensure ease of changing muzzle devices and indexing flash hiders while being fully re-useable. Crush washers are a thing of the past as they are single use and can induce stress and cause problems if used improperly. Bull barrels use shims to time your muzzle device without adding to the diameter of the already rigid barrel.

Alignment dimples are also machined into your barrel at the same time the gas port is drilled to provide 100% accurate positioning of your gas block and to keep it securely in place in spite of recoil. We machine our gas blocks and adjustable gas blocks right here from 4150 US barrel steel to give you the strongest and most durable product possible..
Hardened Arms uppers are high end, accurate, head spaced, inspected and test fired prior to shipping. They are built using stringent specs, top quality parts and procedures to ensure maximum reliability and performance.

You are responsible for knowing your state laws regarding barrel lengths, pistol and short barreled rifle restrictions. 20% restocking fees if you cancel anytime after you order or can not take delivery due to state restriction. Dealer programs are available on our website. Two year warranty against manufacturer defects. Finishes will wear with use, no warranties apply to finish wear. Fits any mil-spec AR15 lower receiver.
