Now available for the Ruger-5.7, the TANDEMKROSS Wingman +5 Magazine Bumpers (2-Pack), are designed to add 5 additional rounds to your factory magazines! These bumpers extend the bottom of the magazine to provide more grip for control of your pistol while firing. The additional material of the extended bumpers also help with more confident magazine changes and proper seating. With the extended area, you can securely seat your magazines by ''bumping'' them into a locked state. Everyone can benefit from a two-pack of these easy-to-install upgrades. Feel free to check out the many reviews of our other Wingman Magazine Bumpers available for the Ruger LCP II in .22LR, Ruger SR22, TaurusTX 22, or Walther P22. As the Ruger-5.7 and Ruger LC Carbine share the same magazines, the Wingman +5 Magazine Bumpers are compatible with both.
