Give your Ruger American a confidence-boosting bolt lift with the MDT Bolt Handle – Clamp-On. Designed specifically for the Ruger American action, this black clamp-on knob delivers a larger, more ergonomic grip surface for quicker follow-up shots, smoother cycling in awkward positions, and surer control with cold or gloved hands—all without replacing your factory handle.
Bigger, better grip: Enlarged outside diameter and textured profile help you find the handle instantly, drive the bolt cleanly, and keep your sight picture steadier between rounds.
No permanent mods: The clamp-on design installs over your existing handle—no machining, no epoxy, no replacement handle—so you can upgrade now and revert later if you choose.
Cold-weather confidence: Gloves, rain, or numb fingers? The oversized knob and knurled contact points reduce slips and short-stroking.
Modern, low-profile style: Matte black finish complements hunting and precision rigs without glare.
MDT quality: Precision-made for repeatable fit and field durability.
