Product Overview

The lightest-breaking flat-bow trigger in Geissele's two-stage line — the SD-E is precision shooting distilled.

The Geissele Super Dynamic Enhanced (SD-E, 05-167) marries the SSA-E's famously crisp, light second stage with the flat trigger bow of the Super Dynamic line. The flat shoe's geometry adds leverage and puts your finger in the same place every shot; the enhanced internals reward that consistency with a break routinely compared to snapping glass. Together they make the SD-E the pick for DMR and precision gas guns whose owners still demand two-stage safety margin.

Geissele's machining and finishing keep the pull identical across thousands of rounds, and full-power springs preserve certain ignition with any duty-grade ammunition. Non-adjustable — because nothing about it needs adjusting.

Why shooters choose the SD-E

Enhanced light second stage — the famed glass-rod break
Flat trigger bow — repeatable finger position, added leverage
Two-stage precision with safety margin — prep, then commit
Full-power ignition springs — reliability without compromise
Made in the USA

Product Questions

Will the SD-E drop into my AR-15 lower?

It is designed as a drop-in for AR-15/M4 pattern lowers with mil-spec trigger pins. Large-pin receivers and some non-standard lowers will not take it, so check your pin size before ordering. If in doubt, measure the pin holes or ask us with your receiver details.

What is the SD-E aimed at?

The SD-E is the Super Dynamic Enhanced: a two-stage trigger on a flat bow, set up as the lighter, more precision-oriented member of the Super Dynamic family. The flat shoe puts your finger lower on the bow, which changes the leverage and makes the break feel more consistent to many shooters. It suits marksmanship and general precision work more than close-range speed shooting.

How does it compare with the SD-C?

Both are flat-bow two-stage triggers, but the SD-C is set up as the combat-weight option with a heavier, more duty-oriented pull, while the SD-E is the enhanced, lighter-feeling one for precision. If the rifle is a working carbine, the SD-C is the safer choice; if it is a target or DMR-style build, the SD-E is the natural pick.

Do I need any other parts to fit it?

No, it assembles into the lower with standard trigger and hammer pins in the usual positions, so no extra hardware is required if your existing pins are in good condition. Anti-walk pins are optional rather than necessary. You can see how it sits against the rest of the range in our AR-15 triggers collection.
