Description
The Area 419 Bighorn TL3/Origin Bolt Knob Adapter is a precision steel upgrade component engineered to accept aftermarket bolt knobs on Bighorn TL3 and Origin bolt-action rifle actions. Machined from solid steel and finished in Black Nitride for corrosion resistance and a low-friction surface, this adapter threads into the factory bolt handle using a 5/16×24 thread pattern.
Designed and manufactured by Area 419 Firearms, this bolt knob adapter allows shooters to customize the feel and ergonomics of their precision rifle’s cycling action with a wide range of compatible aftermarket knobs. The compact, low-profile design preserves the action’s original geometry while giving competitors and hunters a more controllable cocking surface for follow-up shots.
MPN: 419-KNOBADT-BHBN. Engineered specifically for Bighorn TL3 and Origin actions.
