Description
The Geissele Super Dynamic Enhanced (SD-E) is a two-stage trigger built around a flat trigger bow. The flat bow geometry changes the mechanical advantage through the pull, giving shooters a more consistent feel and finer control over break point compared to a curved bow.
Pull weight is split across two stages: 2.3 lb first stage and 1.2 lb second stage, for a 3.5 lb total. That first stage gives you positive wall feel before the second stage breaks, which matters when precision and speed need to coexist. Geissele built this on the same fundamental architecture as their combat-proven two-stage designs, so reliability is not traded for the lighter pull weight.

What platform does the SD-E fit?
Verify fitment for your specific lower receiver before ordering.
How does the flat bow affect the pull compared to Geissele's curved-bow triggers?
The flat bow shifts leverage through the pull cycle, which many shooters find reduces perceived stack and improves consistency at the break. Preference between flat and curved is individual, so if you have not shot both, factor that into your decision.
