The Geissele Super "V" was designed exclusively for Viking Tactics by Geissele Automatics. We have searched for a rugged trigger system that is truly drop in, and allows the tactical shooter to have a hybrid single stage trigger with no surprises. This trigger allows the tactical shooter to have a 4-4.5 lb pull weight with the reliability that Geissele is famous for. No tools or adjustment needed, simply drop in the trigger and you are ready to roll. Only available from VTAC and our dealers and distributors. And yes, the "V" is for Viking Tactics.
