The Area 419 419-KNOBADT-BHBN Bighorn TL3 Bolt Knob Adapter is purpose built to let you run popular aftermarket bolt knobs on your Zermatt Arms / Bighorn TL3 or Origin action. Machined steel with a black nitride finish, it provides a clean, compact way to convert the factory female bolt handle interface to a standard 5/16x24 male thread for broad knob compatibility.

This adapter slightly extends the bolt handle for improved leverage and smoother cycling, while maintaining a low profile that stays out of the way during positional shooting or field carry. Ideal for precision rifle competitors and dedicated range shooters who want a more ergonomic bolt lift, it is also a simple upgrade for any Bighorn TL3 or Origin owner looking to personalize their rifle. Area 419 is known for thoughtful engineering and precise machining, and this adapter reflects that same attention to detail.
