Rainier Arms MARS on RECOILTv Mail Call (full episode)
The Rainier Arms Magazine Advanced Release System (MARS) offers an alternative magazine release method for Glock Gen 1-3 pistols. It's designed for index finger operation, aiming to maintain a consistent grip and potentially speed up reloads by aligning with natural body mechanics. While ambidextrous in capability, its primary design encourages a specific manipulation technique that requires practice to master.
