Key Features
- 20″ Heavy Threaded Barrel — The muzzle is threaded 5/8×24, letting you add a suppressor, brake, or flash hider without a gunsmith. This keeps your setup modular and quiet.
- Howa Mini Action Platform — A shorter, lighter action that still cycles smooth as butter. Paired with the 6.5mm Grendel, you get a compact rifle that handles like a carbine but hits like a full-size rifle.
- Olive Drab Green HTI Stock — This synthetic stock is tough, weather-resistant, and has that low-vis look for the field. It also helps keep the overall weight down without sacrificing rigidity.
- Drilled and Tapped Receiver — Mounting a scope or red dot is straightforward. Just pick your base and rings, and you are ready to zero.
- 5-Round Magazine — A flush-fit detachable box magazine keeps the profile slim while giving you enough rounds for hunting or target work.
Who It’s For
This rifle is a solid choice for hunters who want a lightweight, short-action gun for deer or hogs out to 400 yards. It also fits target shooters who like the low recoil and high ballistic coefficient of the 6.5mm Grendel. New shooters will appreciate the mild report and manageable weight, while experienced hands will value the threaded barrel and aftermarket support.
Pros and Cons
- Pro: Compact and lightweight for a heavy-barrel rifle.
- Pro: Threaded muzzle from the factory.
- Pro: Howa’s two-stage trigger is crisp and adjustable.
- Con: The factory stock is functional but not as rigid as a chassis system. If you plan to shoot groups smaller than 0.5 MOA, you may want to upgrade the stock or bedding.
Comparison
| Feature | Howa Mini Action 6.5 Grendel | Geissele Super Duty AR-15 (6.5 Grendel) | Ruger American Ranch 6.5 Grendel |
|---|---|---|---|
| Action | Bolt action | Semi-auto | Bolt action |
| Barrel Length | 20″ | 16″ | 16″ |
| Threaded Muzzle | Yes (5/8×24) | Yes (1/2×28) | Yes (5/8×24) |
| Weight | 7.5 lbs | 6.8 lbs | 6.5 lbs |
| Magazine Capacity | 5 rounds | 10 rounds | 4 rounds |
| Price | $582.59 | $1,800+ | $550 |
The Geissele is a premium semi-auto, but it costs three times as much. The Ruger American is slightly lighter and cheaper, but the Howa offers a heavier barrel and a smoother factory trigger. For the money, the Howa gives you the most barrel and action quality per dollar.
FAQ
What scope base do I need for the Howa Mini Action?
You need a Howa Mini Action-specific base. The receiver is drilled and tapped for #6-48 screws. Most brands like EGW, Talley, or Leupold make them. Just verify it is for the Mini Action, not the standard 1500.
Can I use AR-15 magazines in this rifle?
No, this rifle uses a proprietary Howa Mini Action magazine. It is a 5-round steel box. Aftermarket options are limited, but Howa offers 10-round versions as well.
Is the barrel threaded for a suppressor?
Yes, the 20″ heavy barrel is threaded 5/8×24, which is the standard size for .30-caliber suppressors. You can mount a suppressor, brake, or flash hider directly.
What is the twist rate on this barrel?
Per Howa specs, the barrel has a 1:8 twist rate, which stabilizes bullets from 85 grains up to 130 grains well.
