The B&T APC9 telescopic stock is a complete factory stock assembly for the APC9 PRO, APC40 PRO, and APC45 PRO. Its retractable design allows the stock to extend into several locking positions or collapse into a compact configuration. The assembly includes our BT-36320 hydraulic recoil buffer and sling attachment loop.

Compatibility

The BT-20394 telescopic stock is designed for the following B&T firearms:

APC9 PRO

APC40 PRO

APC45 PRO

For the APC10, use the separate BT-200579 telescopic stock assembly.

Telescopic Design and Adjustment

The collapsible stock provides adjustable length through a locking mechanism integrated into the assembly. Pull the stock outward to extend it into the desired position. To retract it, press the locking knob and push the stock inward until it locks with an audible click.

The complete assembly includes the stock base, buttplate, guide rods, and release mechanism.

Installation

With the stock extended, remove the lower receiver by pushing out the front and rear takedown pins. Insert the stock into the upper receiver and push it upward, then refit the lower receiver and push both takedown pins back in from the right.

After installation, verify that the stock extends, retracts, and locks properly. Refer to the applicable B&T operator manual for complete instructions.
