	The single best mod you can do. Simple to install. My cheap gauge reads 3lb break with factory trigger. Buy a spare recoil striker assembly as a spare while Midwest has them. Cheap insurance.

	The gear box works extremely well, and really easy to install, not sure if it dropped trigger weight, but definitely made the trigger more crisp!
