Geissele Super Semi-Automatic Enhanced X (SSA-E X) AR-15 Trigger with Lightning Bow

Geissele triggers are trusted by professionals around the world, from special operations forces to competitive shooters. The reason is simple: uncompromising quality, precision manufacturing, and reliability. Each trigger is designed to perform in demanding conditions where smooth operation and consistent shot-to-shot performance are essential.

Geissele SSA-E X is an advanced two-stage trigger and an evolution of the proven SSA-E model. It combines established combat reliability with modern coating technologies and unique trigger-bow geometry, making it particularly well suited to precision-oriented rifles such as Designated Marksman Rifles (DMRs).

Features:

• Lightning Bow® trigger: A unique hybrid profile combining elements of a flat and curved trigger, providing optimal finger placement, improved control, and reduced trigger slap.

• Nanoweapon® coating: The trigger body and hammer feature a Picatinny DSL nanocoating with hardness approaching that of synthetic diamond. It increases resistance to corrosion and wear, simplifies cleaning, and allows the trigger to operate with minimal lubrication.

• Trigger characteristics: A smooth first stage followed by an exceptionally crisp, predictable second-stage break.

• Reliability: Equipped with a chromium-nitride-coated disconnector to further enhance the durability of the system.
