S7 M508 Safety - AR308 Super Safety w/ Trigger Option

This is our checkered S7 tool steel M508 Super Safety for AR10s/AR308s and other firearms using an AR308 receiver set. 

This will not work on "small frame" 308s such as the Ruger SFAR/ DPMS Gen2/ POF Revolution/ etc. 

It is made up of our standard, heat treated S7 steel CHECKERED cam & S7 steel M508 lever - with the lifter spring assembly (machine screw/lock washer/spring) installed . The Safety includes a stainless machine cut detent and a choice to add a compatible trigger. 

If you do not understand the installation requirements of the M508 Safety, please email us for clarification before damaging or breaking the M508 Safety. It is slightly more involved than a standard AR15 Super Safety installation and the modification of the upper MUST be performed in order to not damage or break the M508 Safety.  

*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
