The Rainier Arms MARS (Magazine Advanced Release System) for Glock, designed by Battleline Industries, is a drop in release which is compatible with Glock 43X/48 pistols. The MARS is made of 6061-T6 aircraft grade aluminum, with a Type III Class 2 MIL-SPEC hard coat anodizing finish and stainless steel hardware for maximum corrosion resistance and durability. The MARS control surfaces are slightly extended and feature an aggressive texture for a faster reload and positive control. 

The MARS is COMPLETELY ambidextrous, giving both left and right hand shooters as well as competitors, a tactical advantage with the ability to release the magazine using the index finger from either side.  The MARS is a force multiplier in a combative situation, enabling the left and right hand shooter better options to manipulate magazine changes with speed and efficiency without disturbing the proper firing grip and allowing for more accurate follow up shots.
