HOWA Mini Action 6mm ARC Barrelled Action

Built for precision shooters, varminters, and hunters who demand accuracy from a compact platform, the HOWA Mini Action 6mm ARC Barrelled Action delivers Japanese-made quality in a lightweight and modular setup ready for your next build.

Compact Powerhouse in 6mm ARC

The 6mm ARC (Advanced Rifle Cartridge) was developed for modern sporting rifles, offering flat trajectories and excellent down-range performance without the recoil of larger calibres. Pairing this efficient round with the HOWA Mini Action gives you a fast-cycling, short-throw bolt rifle that’s lighter, smoother, and more compact than a standard short action.

Whether you’re chasing foxes out west or punching tight groups at the range, this combo keeps weight low and accuracy high.

Precision Barrelled Action

Each HOWA Barrelled Action is machined in Japan to strict tolerances for consistent head-spacing and superior accuracy. The cold-hammer-forged barrel provides excellent rigidity and long-term precision, while the one-piece forged receiver offers smooth bolt travel and exceptional durability.
