Why the Howa M1500 Mini Action .22 ARC Delivers Next-Generation .22 Centrefire Performance

Mini Action — Correctly Sized for the .22 ARC Cartridge
The Howa M1500 Mini Action receiver is purpose-designed for AR-15-length cartridges including the .22 ARC, providing a shorter and stiffer receiver than a standard short action that is correctly sized for the .22 ARC case length. The Mini Action provides faster bolt cycling than a standard short action and contributes to the platform’s compact, lightweight handling characteristics that make it ideal for field use and extended range sessions.

.22 ARC — Hornady’s High-BC .22 Centrefire Cartridge
The .22 ARC (Advanced Rifle Cartridge) is Hornady’s newest AR-15-length centrefire cartridge, designed as a necked-down variant of the 6mm ARC case to drive heavy, long, high ballistic coefficient .224 calibre projectiles at velocities and trajectories that significantly exceed traditional .223 Remington and .22-250 Remington performance. The fast 1:7″ twist rate of the .22 ARC barrel stabilises projectiles of 77 grains and heavier, enabling the cartridge to use the same class of high-BC ELD-M and ELD-X bullets that made the 6mm ARC and 6.5 Creedmoor famous for long-range performance. The result is a .22 centrefire that shoots flatter, bucks wind better, and retains energy at distance more effectively than any previous .22 calibre AR-15-length cartridge. In a bolt action platform the .22 ARC delivers its full accuracy potential for varminting, predator hunting, and long-range precision shooting.

Cold-Hammer-Forged 20″ Blued Heavy Barrel — 1:7″ Twist Rate
The Howa M1500 Mini Action .22 ARC 20″ heavy barrel is cold-hammer-forged steel in a heavy varmint contour, finished in matte blue. The heavy profile improves barrel stiffness and heat management during extended varmint and predator sessions. The 1:7″ twist rate is the defining feature of the .22 ARC barrel, stabilising the heavy high-BC projectiles that give the cartridge its long-range advantage over earlier .22 centrefire options.

Threaded 1/2×28 Muzzle with Thread Cap — Suppressor and Muzzle Device Ready
The Howa M1500 Mini Action .22 ARC barrel is threaded to 1/2×28 TPI with a thread cap included, allowing direct fitment of .22 centrefire suppressors, muzzle brakes, and flash hiders without gunsmithing. The .22 ARC is an excellent suppressor host, producing minimal sonic signature when using subsonic or near-subsonic loads.

HACT Two-Stage Trigger — Precision-Focused Factory Trigger
The Howa M1500 Mini Action barrelled action includes the HACT (Howa Actuator Controlled Trigger) two-stage trigger system. Self-contained and attached to the receiver via a single Allen screw, the HACT delivers a clean, predictable two-stage pull with a defined take-up and crisp break, adjustable for pull weight to suit varmint, hunting, or precision field use.

Three-Position Safety for Safe Field Handling
The Howa M1500 Mini Action features a three-position safety on the right side of the receiver: forward for fire, middle for bolt operation with trigger locked, and rear for full bolt and trigger lock during carry.

Drilled and Tapped Receiver — Compatible with Remington 700 Bases
The Howa M1500 Mini Action receiver is drilled and tapped for scope mounting and compatible with standard Remington 700 two-piece scope bases, providing access to the widest range of aftermarket optics mounting solutions.

Sub-MOA Accuracy Guarantee
Howa guarantees the M1500 Mini Action barrelled action to produce sub-MOA groups with appropriate factory ammunition.
