@Ikyo and
@MDT_OFFICIAL yes, we do make a chassis that will work with the Ruger American barreled action in 7.62x39, and that is our LSS-XL Gen2 for the Ruger American SA AR. If you have an earlier version that is set up to run out of the Ruger Mini 30 magazines, you may run into some feeding issues, however, the current models feed just fine
