Description
The 6mm ARC has earned its spot as one of the best do-it-all cartridges for predators, deer, and steel, and Howa built this Fence Line around it the right way. The heart of the rifle is the M1500 mini action, sized specifically for short cartridges like the ARC, which means less bolt travel, faster cycling, and a lighter overall package than a short action doing the same job. Howa has been machining the 1500 action in Japan since 1979, and every Fence Line rifle carries a sub-MOA guarantee of one inch or better at 100 yards, backed by a lifetime warranty against manufacturing defects.
What Sets the Fence Line 6mm ARC Apart
This 20 inch version wears a stiffer varmint-profile barrel, hammer forged for long service life and finished in Cerakote to shrug off weather and hard use. The muzzle is threaded and a radial brake comes installed, so you can tame what little recoil the 6mm ARC produces or spin on a suppressor without a trip to the gunsmith. The shorter tube also balances well with a can attached, which is a big part of why this configuration gets snapped up. Feeding comes from a 5-round detachable magazine, a feature exclusive to the mini action Fence Line models, and the receiver is drilled and tapped for your optic setup.
Trigger, Bolt, and Controls on the M1500
Howa's HACT two-stage trigger gives you a light take-up followed by a clean, crisp break that helps you get the most out of that accuracy guarantee. The bolt runs a 90 degree throw with dual locking lugs and an M16-style extractor for positive cycling and reliable case removal in dust, cold, and rain. A three-position safety lets you cycle the bolt and unload with the safety engaged, or lock the bolt down completely for the walk back to the truck.
The Prairie Reaper camo synthetic stock rounds out a rifle that feels equally at home in a coyote field, a deer stand, or on the bench. For anyone wanting a suppressor-ready ARC bolt gun that shoots better than its price tag suggests, this one is tough to pass up.

Frequently Asked Questions
Is the Howa M1500 Fence Line accurate enough for long range work?
Yes. Every Fence Line rifle carries Howa's sub-MOA guarantee, meaning one inch or better groups at 100 yards with quality ammo. The hammer forged barrel and HACT two-stage trigger do a lot of the heavy lifting there, and the 6mm ARC cartridge itself was designed to stay supersonic well past 1,000 yards.
Can I put a suppressor on the Fence Line 6mm ARC?
The 20 inch barrel comes threaded from the factory with a radial muzzle brake already installed. Remove the brake and you can thread on a suppressor directly. The shorter barrel length on this model makes it a popular pick for suppressed setups since the overall package stays manageable.
Does this Howa Fence Line use a detachable magazine?
It does. The mini action Fence Line models, including this 6mm ARC, feed from a proprietary 5-round detachable magazine, while the short and long action versions in the series use a hinged floorplate instead. One magazine ships with the rifle.
What is the difference between the 20 inch and 22 inch Fence Line in 6mm ARC?
The 22 inch version runs a standard sporter profile barrel, while this 20 inch model wears a heavier varmint-style profile. The stiffer barrel adds a bit of weight but resists heat-related shift during longer strings, and the shorter length balances better with a suppressor. Both are built on the same mini action with the same sub-MOA guarantee.
