The M9 Bayonet | Autotronic is one of the most readable red industrial skins in the Gunsmith line: deep anodized red across the blade, with precision steel mesh panels that match Valve’s “lighten the weight” fiction. From third person it reads as a clean crimson slab; in inspect, grid lines and bevel breaks give it real depth. If you’re building a red loadout or collecting Gamma-era knives, this finish usually lands on the short list—not because it’s loud, but because the material split stays obvious even after hours of flipping.

What you’re actually buying

Gunsmith zoning means flat red planes vs mesh stay separated until high wear scrubs the contrast. Mythical rarity on a knife still means condition drives the invoice more than on a same-name rifle skin—float, tip, and screenshot honesty matter.

Inspect checklist

• Mesh placement can differ at the same float—open several listings and compare grid coverage on the spine and belly.
• Wear climbs on edges first—tip and back of the blade often fade or show base metal before the flats.
• Factory New hunters: prioritize a clean tip and even red on the point; one chipped-looking tip can tank the “premium FN” feel.
• Budget Battle-Scarred: the 0.85 cap leaves room for cheaper tiers if you only care about silhouette and flip animation.

Shop verdict

Worth it if you want a Gamma signature red knife with clear Gunsmith read at mid wear, or you’re theming crimson across knives and gloves.

Think twice if you need pixel-perfect grid symmetry—pattern variance is real—or you’re paying FN money without verifying tip and spine in in-game inspect.

Where to buy: Compare the same float band on C5GAME and Steam; confirm Gunsmith finish, exact wear, and that the listing screenshot matches what you see in inspect.

Editor’s nitpicks

Autotronic on M9 is a slow burn skin: it doesn’t rely on holo tricks—it relies on anodized red staying true and mesh staying sharp. I’ve passed on “cheap FN” listings because the tip looked BS in inspect. Conversely, a 0.80+ BS with muted mesh but solid red on the handle side can be a fine play knife if you’re not streaming your inventory. Unbox path is strictly Gamma / Gamma 2—for most buyers, secondary pick-by-screenshot is the sane route. When in doubt, inspect three times, then haggle once.
