The Accu-Shot BT0857-B Replacement Bolt, part number BT0857-B from B&T Industries, is the standard M6 × 80 × 80 bolt for the BT08-QK and BT57-QK Accuracy International monopods. It is the correct spare when the original bolt is lost or damaged.
How It Compares
The BT0857-B is the standard-length bolt. If your rifle has additional length-of-pull spacers fitted, the longer Accu-Shot BT0857-LB replacement bolt in M6 × 80 × 100 is required instead. The monopods these bolts belong to are the Accu-Shot BT08-QK ASAI monopod for AE, AW and AICS pattern stocks and the Accu-Shot BT57-QK ASAIAT monopod for the AI AT. Both are in our Accu-Shot monopod range.
Ideal For
- Accuracy International rifles fitted with a BT08-QK or BT57-QK monopod
- Replacing a bolt lost during a stock strip or rebuild
- Keeping a spare with the rifle's kit
