22 ARC Upper Assemblies
The .22 ARC is designed for exceptional long-range precision and aerodynamic efficiency, launching high-BC .22 caliber bullets such as 75–90 grain projectiles at moderate velocities optimized for stability and retained energy. This combination delivers a very flat and predictable trajectory, along with significantly improved wind resistance compared to traditional .223/5.56 loads, making it highly effective on small to medium targets at extended distances well past 500 yards. When paired with the AR-15 platform, the .22 ARC offers a refined balance of manageable recoil, excellent barrel life potential, and consistent match-grade accuracy. Overall, it emphasizes controlled long-range performance and efficiency over raw velocity, making it a purpose-built cartridge for precision shooting applications.
BallisticBarn.com builds each 22 ARC complete upper receiver to order, with thoughtful available options focusing on the needs of varmint hunters and precision shooters. Every upper is assembled in-house, checked for proper headspaced with Manson Go and No-Go gauges and tested for fitment plus function to ensure reliable operation. To match your preferences, each upper can be configured with your choice of barrel length, handguard and receiver finish, muzzle device, and adjustable gas block along with several options for bolt carrier group and charging handle.

Why Upgrade to a 22 ARC Upper Assembly? Precision Performance & Ballistics
22 ARC: AR-15 Power Goes Long Range
The 22 ARC (Advanced Rifle Cartridge) has redefined the ballistic ceiling of the AR-15 platform. By choosing a purpose-built 22 ARC Upper Assembly, you are transitioning from a standard 5.56 NATO carbine to a high-velocity, long-range precision system capable of rivaling the .22-250 Remington. Our uppers are engineered to maximize the 22 ARC’s unique geometry, utilizing a 1:7 twist rate to stabilize heavy-for-caliber, high-BC bullets that maintain supersonic speeds well beyond the 1,000-yard mark. Our 22 ARC upper receivers utilize a 6.5 Grendel Type II bolt carrier group since the parent case of the 22 ARC is 6.5 Grendel.
Performance Advantage
By integrating a purpose-built 22 ARC upper with your standard AR-15 lower, you gain a long-range precision system without the need for proprietary magazines or a new rifle platform. Whether you are dialing in at distance or engaging small game in the field, these uppers are engineered around a 1:7 twist and 6.5 Grendel Type II bolt compatibility to deliver exceptional stability, consistent accuracy, and sub-MOA potential in real-world conditions.
Industry Experience
All Ballistic Barn AR-15 uppers are American Made and machined by manufacturers of high quality, industry specific, mil-spec AR-15 components. Every upper we ship is individually checked for headspace using Manson go and no-go gauges prior to shipping to ensure safety and proper function. Pick from our 22 ARC upper assemblies selection of different length barrels and materials like 416R stainless steel to satisfy your project goals. 22 ARC is rapidly becoming a favorite caliber on the market for those seeking a leg up on 5.56/223.

Why It Matters
| Feature | Specification | Why It Matters |
| Cartridge | 22 ARC (Hornady) | Delivers bolt-gun ballistics (22-250) in a semi-auto AR-15, offering flatter trajectories and higher velocity. |
| Barrel Twist | 1:7 or 1:8 Twist | Specifically engineered to stabilize modern, heavy, high-BC projectiles (like 62gr-88gr) for extreme long-range accuracy. |
| Gas System | Rifle-Length | Softens the recoil impulse and slows down the action, reducing parts wear and keeping your sight picture steady. |
| Bolt Face | 6.5 Grendel (Type II) | The 22 ARC uses a larger casing base; a Grendel Type II bolt is required for proper extraction and headspacing. |
| Barrel Material | 416R Stainless Steel | Provides match-grade precision and superior corrosion resistance, ideal for precision varmint and target rifles. |
| Handguard | M-LOK Free-Float | Eliminates pressure on the barrel for better harmonics and allows easy mounting of bipods, lights, or ARCA rails. |
| Muzzle Thread | 1/2x28 TPI | The industry standard for .224 caliber bores, making it easy to swap the flash hider for a suppressor or muzzle brake. |
22 ARC Upper FAQs
Does the 22 ARC upper come ready to use?
Yes. All of our uppers are fully assembled, inspected, tested for fitment and function, and professionally checked for proper headspace using Manson Go and No-Go gauges before shipping. Since an upper receiver assembly is not a firearm, it can ship directly to your home.
Is a 22 ARC upper compatible with a standard AR-15 lower?
Yes. A 22 ARC upper is designed to work with a standard AR-15 lower receiver machined to mil-spec dimensions, provided that the proper bolt, magazines, and related components are used.
What bolt carrier group do I need for a 22 ARC upper?
A standard AR-15 bolt carrier can be used, but it must be equipped with a compatible 6.5 Grendel Type II bolt featuring a .136-inch bolt-face depth. A standard 5.56 NATO bolt is not compatible with 22 ARC ammunition.
What magazines are used with a 22 ARC AR-15 upper?
A 22 ARC upper commonly uses AR-15 magazines designed for 6.5 Grendel ammunition. Feeding reliability can vary depending on the magazine manufacturer, internal geometry, condition, and capacity.
What is the effective range of a 22 ARC AR-15?
The practical effective range of the 22 ARC depends on the rifle, barrel length, ammunition, environmental conditions, and intended application. For predator and varmint hunting, it is commonly used from approximately 300 to 600 yards. With an appropriate barrel and high-ballistic-coefficient ammunition, the cartridge can also remain supersonic beyond 1,000 yards for long-range target shooting.
Is the 22 ARC good for hunting?
Yes. The 22 ARC is well suited for varmint and predator hunting because of its accuracy, flat trajectory, and improved resistance to wind drift compared with many conventional .223 Remington and 5.56 NATO loads. The practical hunting range depends on the target animal, ammunition, environmental conditions, and proper shot placement.
What barrel length is best for a 22 ARC upper?
Barrel lengths from approximately 18 to 20 inches provide a useful balance of velocity, accuracy, weight, and handling. Longer barrels may produce additional velocity, while shorter barrels can provide a lighter and more maneuverable rifle.
Does a 22 ARC upper have more recoil than .223?
The 22 ARC generally produces slightly more recoil than typical .223 Remington or 5.56 NATO ammunition because it can use heavier bullets and a larger powder charge. Recoil remains mild and manageable in the AR-15 platform.
Is the 22 ARC upper good for long-range shooting?
Yes. The 22 ARC is designed to use high-ballistic-coefficient .22-caliber bullets that retain velocity and resist wind drift at extended distances. This allows it to deliver stronger long-range performance than many conventional .223 Remington and 5.56 NATO loads while remaining compatible with the AR-15 platform.
How long until my order ships?
We generally ship orders within one to three business days, depending on order volume. During seasonal holidays or periods of unusually high demand, shipping may take two to five business days. Tracking information is emailed as soon as the order ships.
Why should I order a 22 ARC upper from Ballistic Barn?
