The vision mid section for TRG-42 is a highly robust but light weight part machined from 7075 t651 aluminum
This variant fits ar-15 style grips and comes with a wide magazine release that overlaps the trigger guard and therefor you do not have to move your finger far and is extremely easy to engage contrary to other magazine releases that are insanely small.
The mid section has a built-in bubble level at the rear end of the action insert, rounded barricade stop for perfect stability in every position,
mounting points on both sides over the trigger guard for mounting of different accessories like timer mount and thumb rest
