The BX-Trigger™ is a light, crisp, "drop-in" replacement trigger assembly that is compatible with all Ruger® 10/22® rifles 
and 22 Charger™ pistols. The BX-Trigger™ is a Genuine Ruger Factory Accessory and is the perfect upgrade for all 10/22® rifles 
and 22 Charger™ pistol models because of the significantly reduced pull weight of approximately 2.75 lbs. (versus 6 pounds 
on the standard 10/22® trigger). The BX-Trigger™ is sold as a complete assembly that drops in to replace the existing 
trigger assembly. A video of the installation process can be found at Ruger.com/BX-Trigger.
