Upgrade your Ruger® Mark IV™ or Mark IV™ 22/45™ with the TANDEMKROSS Blast Shield Magazine Disconnect Replacement. This easy drop-in upgrade allows for safe removal of the factory magazine disconnect while adding performance-focused benefits for rimfire shooters.

The Blast Shield helps your Ruger Mark IV fire whether or not a magazine is inserted, while also improving magazine alignment and helping shield the sear and hammer from debris. It is a simple but effective upgrade for competition shooters, range use, and weekend plinking.

Designed for reliable function, the TANDEMKROSS Blast Shield works with the Volquartsen sear and disconnector, while being designed around use with the factory hammer.
