The Accu-Shot BT0857-LB Replacement Bolt, part number BT0857-LB from B&T Industries, is the long M6 × 80 × 100 bolt for the BT08-QK and BT57-QK Accuracy International monopods. It is the bolt required when additional length-of-pull spacers are fitted to the rifle.
How It Compares
The extra length is the whole point: at standard length of pull, the shorter Accu-Shot BT0857-B replacement bolt in M6 × 80 × 80 is the correct part. 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

- BT08-QK and BT57-QK monopod owners adding spacers
