Franklin Armory PC-C1: The Ruger Charger came on to the scene when pistol caliber carbines were gaining popularity again. They are light, mobile, modular, and come at a fantastic price, which Ruger is known for. Franklin Armory is known for its binary trigger system, which they want to put in every firearm platform they can. The very popular Charger was their next stop on the road to making all guns shoot fast. They are robust and reliable, with all of the safety features needed in a trigger like this. Another excellent feature of the PC-C1 is the ability to release the next round in binary mode by simply switching back to position 2 in semi. That will reset the trigger and keep the gun from firing on the release of the trigger. The PC-C1 is ingenious and wonderfully engineered. This trigger belongs in every Charger. If you own one, you really are missing out on something spectacular if you don\'t choose this trigger. This item cannot ship to California, the District of Columbia, Iowa, New Jersey, New York, Hawaii, Rhode Island, Flordia, Maryland, Connecticut, Washington, Oregon, Massachusetts. Manufacturers Note: The release round can be canceled by simply moving our Patent Pending selector out of Binary mode while holding the trigger back.
