I modified a Geissle trigger to offer 3 positions - safe, SSA, then S3G
I know Bill Geissele said on TOS he already made one and was waiting on the ATF for approval. I got tired of waiting and made my own. It has safe, a SSA like position 2, and S3G like position 3. I'm still playing around with the timing of the wall in position 2 as well as the spring rates. I'll follow this video up with another using a trigger pull gauge hopefully this weekend and another live fire demo. Enjoy...
