Geissele Automatics Super Dynamic Enhanced SD-E 2-Stage AR-15/AR-10 Flat Bow Trigger 3.5 lb - Black

The Geissele Automatics Super Dynamic Enhanced (SD-E) is a precision-engineered two-stage trigger built for the AR-15 and AR-10 platforms. Part of Geissele's Super Dynamic line, the SD-E is a rugged, non-adjustable combat trigger with a sear design that provides a wide margin of safety against unintentional discharge.

Pull weight is split between a 2.3 lb first stage and a 1.2 lb second stage for a total pull of approximately 3.5 lbs. At that weight the SD-E comes in lighter than a standard AR-pattern mil-spec trigger while retaining the safety margin and defined break of a two-stage design. The flat trigger bow sits naturally under the shooter's finger and provides consistent placement from shot to shot, and the smooth, predictable let-off has made the Super Dynamic series a long-standing benchmark for AR-pattern rifles.

The SD-E installs in any standard AR-15 or AR-10 lower receiver using standard Mil-Spec pin geometry. Finished in black, the Geissele SD-E is a drop-in upgrade for shooters stepping up from a stock trigger without sacrificing reliability.
