Lightly used Geissele Fire Control Groups (pins included) for the AR platform. These FCGs have seen minimal use and remain in excellent condition. Per Geissele, the SSA has a two-stage trigger with a total pull of 4.5#, and the SSA-E has a two stage trigger with a total pull of 3.5#. Only $150 cash per set, not looking for trades. Pickup in the Gulf Breeze/Midway area. Please make all contact using the forum's PM/Conversation function. Thanks for looking.
