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.
Review by Jeff on 29 Mar 2020review stating Fits Well and Doubles as an Ambi Release
Bought this and wasn't sure what to expect. It really does work as an ambi release. Works well with both OEM mags and the S15 mags. 3rd release I've tried from various manufacturers and this one is by far the best.

Q: The RAINIER ARMS MINI MARS (MAGAZINE ADVANCED RELEASE SYSTEM) FOR GLOCK 43X/48 doesn't work with the shield arms magazine? The comments are saiyng the oposite.

A: The M.A.R.S. is not rated to be used with the Shield Magazines because it will significantly decrease life of the magazine release.
