TG2000 & TGS - What's the Difference?

The TG2000 Trigger Group is designed for use in our semi-auto 22 LR rifles as well as an aftermarket option for the 10/22 platform. The TGS Trigger Group is designed specifically for use with our Summit toggle bolt-action rifles. With the TGS being used on our bolt-action rifle it does not have a bolt hold open and the ejector is integrated into the front of the housing. The TG2000 has a trigger pull weight of 2.25# while the TGS has a trigger pull weight of 1.75#. Both are set at the factory.
