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 don't understand the different installation requirements of the M508 Safety, please email us for clarification before damaging or breaking the 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.
