Geissele Automatics SD-E Super Dynamic Enhanced 2-Stage Trigger AR-15

The Geissele Super Dynamic Trigger is the semi-auto only version of a select fire trigger that Geissele makes for customers in the U.S. Special Operations community. The SD is a non-adjustable combat trigger, with a stunningly smooth 1st stage and solid 2nd stage built for use in the adverse environment of battle. Suitable for Close Quarters Battle (CQB) and mid-range carbine work, the Geissele SD is also the perfect trigger for Squad Designated Marksman (SDM) rifles. The trigger features tool steel construction with wire EDM cut sear surfaces. Total pull weight is 4.5lbs (2.5lb 1st stage/2lb 2nd stage). Instructions are included. This trigger features a flat trigger bow for a consistent trigger feel regardless of finger placement. The flat trigger bow is also 0.141" forward of a standard AR-15 trigger resulting in an increased trigger reach for proper placement on the trigger finger. Notes: Combat: 2-1/2 - 3lb 1st stage, 2lb 2nd stage Enhanced: 2.2 - 2-1/2lb 1st stage, 1.2lb 2nd stage
