HK Army Paintball Ball Sizer Tool – 9 Bore Sizes | Multi-Tool with Carabiner

The HK Army Ball Sizer is a compact, multi-purpose paintball tool designed to help players get the most accuracy and consistency out of their setup—whether you’re a weekend woodsball player or a competitive tournament shooter.

Featuring 9 precision laser-engraved ball sizing gauges, this tool allows you to quickly measure paintball diameter and match it to the correct barrel bore size. Proper bore matching improves air efficiency, reduces roll-outs, and delivers more consistent shot placement—especially critical when paint quality varies.

Machined from durable aluminum, the HK Army Ball Sizer is built to survive life in a gear bag or clipped to your kit. Beyond paint sizing, it functions as a true multi-tool, incorporating a tank extender wrench, tape cutting edge, and bottle opener—perfect for quick field adjustments and downtime between games.

A built-in HK Army carabiner makes it easy to clip the sizer to belt loops, backpacks, pod packs, or lanyards, ensuring it’s always within reach when you need it most.

Lightweight, rugged, and endlessly useful, the HK Army Ball Sizer is one of those tools you’ll wonder how you played without.
