The Geissele Super Semi-Automatic Enhanced AR Trigger is based on the same trigger currently deployed with USSOCOM and is designed to fit most small pin AR rifles. The trigger excels at providing you with a crisp pull that is ideal for target and competition shooting. The SSA-Es reduced first and second stage pull weights result in a trigger with a smooth, light first stage take-up and a crisp, candy cane-like second stage break.
