Usage & installation instructions

1. Confirm your barrel is threaded 1/2x28 and that your suppressor is an SN‑style SilencerCo quick‑attach model.

2. Ensure the firearm is unloaded and follow all safety protocols.

3. Thread the piston onto the barrel by hand until snug; use the recommended wrench or tool for final seating per SilencerCo torque guidance. Do not overtighten.

4. Attach the suppressor to the piston per the suppressor manufacturer’s instructions and confirm positive lock engagement.

5. After initial installation, perform a function check and, if possible, a proof/verification shot per manufacturer's guidance to confirm alignment and safe operation.

6. After use, remove the suppressor, inspect engagement surfaces, clean threads, and apply the recommended protective lubricant before reassembly.

Compatibility & safety notes

• Verify thread pitch (1/2x28) and right‑hand orientation on your barrel before ordering. Incorrect thread selection can damage threads or prevent secure attachment.

• Always follow SilencerCo’s installation and usage instructions for both piston and suppressor.

• Perform alignment and point‑of‑impact checks after installation and before live use.

• Consult a qualified gunsmith if you have any doubt about fitment, torque, or safety.
