Frequently Asked Questions

What tools are required to reverse the safety selector on a CMMG BR Series lower receiver?

You will need a T8 Torx wrench to remove the trigger pin screws and a 1/16th inch hex wrench to loosen and tighten the safety selector's set screw. A vice is recommended but not strictly necessary.

What are the small parts involved in the safety selector reversal process?

The process involves a small spring and a ball detent that sit underneath the safety selector's set screw. These parts are crucial for the safety's function and must be handled carefully to avoid loss.

How do you properly reinstall the safety selector after reversing it?

Ensure the detent cutouts on the safety selector face upwards. Reinsert the ball detent and spring into the receiver, then carefully guide the safety selector into place, aligning it with the detent and spring.

What is the correct torque specification for the safety selector set screw?

The set screw for the safety selector does not require high torque. It only needs to be snug enough to retain the internal spring and detent, ensuring it is flush with the surface and does not cause interference.
