Product Overview

This is our standard, heat treated S7 steel Checkered cam (machine cut textured ends) that's been paired with the redesigned heat treated S7 steel M508 lever and lifter spring assembly for use in your AR308 variant*

If you don't understand the different installation requirements of the M508 Safety, please email us for clarification.

*The lower rear section of the bolt carrier must measure 2.20"+- in order for the Safety to work correctly. Using a 2.40"+- BCG can damage or break the lever. The upper receiver must be trimmed flush with the rear take down lug to give the lever the proper clearance. This is not a "drop in" part. We do not accept returns for modified parts.

Awesome trip

Posted by Frederick ledger on Feb 16th 2026

This trip is awesome! Let me just say if as any part it required alil fitment of the top of the lever, but no points against it there. I'd give it 5 stars but it doesn't come with a centering block which is a preference of mine. Love it and it works great!
