Specifications
September 2026 on GunPartPicker
Geissele Automatics G2S Two Stage AR-15 Trigger .154" was the ninth most added trigger on GunPartPicker in September 2026, behind the Geissele Automatics Super Semi-Automatic Enhanced SSA-E Two Stage AR-15 Trigger .154", with about 3% of all triggers added to builds. Up from #14 in August. Builds with this trigger are nearly all chambered in 5.56 NATO, mostly on mid-length gas (94%), and nearly all AR-15.
Availability is good: it was in stock at one retailer or another nearly every day in September 2026, and today 9 of the 11 retailers we track have it in stock. Prices barely moved in September 2026, holding around $139.49, so there haven't been real sales lately. Buying today, the lowest price is $147.67 at KY Gun Company, above September's low of $139.49, so a better deal may come back.
