The TacSol PMR (Performance Magazine Release) is a low profile, easy-to-use magazine release for the Ruger 10/22 and TacSol X-Ring rifles. The Performance Magazine Release is a shorter design than the popular TacSol Extended Magazine Release. This magazine release is easy to install and makes removing your magazine easy without searching for the magazine release button. It is machined from a solid block of 6061-T6 aluminum and is designed to conform to the shape of the trigger guard. The magazine release is laser engraved with the "TacSol" name.
