AR-15 – Two-Stage Trigger – SD-E – Flat Bow
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
Geissele Automatics built the SD-E as the flat-bow counterpart to the SSA-E, giving AR shooters a lighter two-stage pull with a straighter trigger face and a more consistent feel across the press. It is a serious trigger for people who actually care what the break feels like.
Fitment
- Fits mil-spec AR-15 pattern lower receivers using standard small-pin trigger geometry
- Semi-auto trigger assembly for AR-platform rifles
What it does
The SD-E provides a smooth first stage and a crisp second-stage break, with the flat bow changing finger placement and helping some shooters get a more repeatable press.
Why it’s worth it
If you like a flatter trigger face and a lighter precision-oriented two-stage pull, this one makes a lot of sense. It keeps Geissele’s strong reputation without turning the rifle into a fragile science project.

Verify before you buy
Verify standard AR lower compatibility and make sure you actually want a flat-bow trigger instead of a curved bow before you spend the money.
