Geissele G2S Two-Stage Trigger - AR-15 (05-145)

Geissele's gateway two-stage trigger — the G2S delivers the house pull at the sharpest price in the line-up.

The Geissele G2S (05-145) exists to put a genuine Geissele two-stage into more rifles. The pull follows the SSA's celebrated profile — smooth first-stage take-up into a crisp, reliable second-stage break — manufactured with streamlined production to reach a price point, not by cutting the metallurgy or the safety margin that make Geissele triggers trustworthy.

For a first trigger upgrade, the G2S is transformative: mushy, gritty factory pulls become a clean two-stage you can actually shoot to the rifle's potential. It drops into any Mil-Spec AR lower and runs duty ammunition with full-power ignition reliability.

Why shooters choose the G2S

• True Geissele two-stage pull — SSA character, accessible price
• Crisp, repeatable break — an immediate upgrade over any factory trigger
• Full-power ignition springs — reliability uncompromised
• Drop-in Mil-Spec fit — standard .154 in pins
• Made in the USA
