The Geissele SSA-E X trigger with Lightning Bow (Geissele part no. 05-960) is a two-stage trigger for AR-15 and AR-10 rifles with a semi-curved, wide-body shoe that blends a standard curved trigger with the flat-bow style. Geissele describes a smooth, light first-stage take-up and a crisp second-stage break. The major components carry the Nanoweapon coating for wear and corrosion resistance. It is aimed at precision Designated Marksman type rifles where accuracy and reliability both count.

Key Specifications

• The platform is AR-15 and AR-10, built for mil-spec AR-pattern lowers.
• The trigger is a two-stage design, with a defined take-up before a clean break.
• First-stage weight is 2.0 to 2.5 pounds, a light take-up that is easy to control.
• Second-stage weight is 0.9 to 1.3 pounds, for a crisp break.
• Total pull weight is 2.9 to 3.8 pounds, all weights approximate.
• The trigger is not adjustable, so it ships set from Geissele.
