FMTS aggregates fit evidence from specifications, owners, manufacturers, and occasional first-party testing. A fit report documents that parts mate; it is not a certification that a product is safe to load.

Recommend, mixed, or don't-recommend from people who own the Mutant Metals ARC Dual-Thread Weight Horns. No stars and no average — a rating out of five hides more than it says. Verdicts inform you; they never move this product's ranking anywhere on the site.

Verdicts are account-gated — no anonymous reviews. It keeps the section accountable and stops the spam that eats open review boxes.
