HERA Arms Triarii Stock Conversion

The HERA Arms Triarii is the premium, German-engineered chassis in the Glock conversion category. It wraps an unmodified Glock in a tightly toleranced shell with a full-length rail forend that surrounds the slide and barrel, giving more continuous mounting space than the open-frame clamshells. The fit and finish reflect HERA's European manufacturing pedigree.

The Triarii is model and generation specific, with SKUs for Glock 17/22/31 (Gen 3 and Gen 4/5), Glock 19/23/32 (Gen 3 and Gen 4/5), and Glock 34/35 (Gen 3/4). HERA states the chassis accepts AR15 buttstocks for an SBR configuration as well as pistol braces, so the same body can be built either way depending on the paperwork and the parts on hand. The full-rail forend carries optics, lights, and a forward grip without add-on rail sections.

For a shooter who wants a refined chassis with continuous rail real estate and the flexibility to run an AR stock or a brace, the Triarii is the premium pick. The model-specific fitment means buyers must match the SKU to their exact Glock and generation, but the payoff is a tighter fit than universal kits deliver.
