The Geissele Super Dynamic trigger allows precise and accurate trigger control under various usage conditions. They make a great drop-in replacement for that old, clunky Mil-Spec trigger found in most AR-15/AR-10 rifles.

The SD-C is what Geissele considers a combat trigger, with a heavier pull and a more pronounced break, while the SD-E has a lighter pull and a sharp, quick break. They are precision machined from S7 tool steel which provides excellent impact resistance, strength, and toughness. Geissele triggers are known for their consistent, long-lasting performance.

The Super Dynamic-Combat (SD-C) and Super Dynamic-Enhanced (SD-E) provide the same two-stage trigger pull as the Super Semi-Automatic (SSA) and Super Semi-Automatic Enhanced (SSA-E). But instead of the M4 curve, the Super Dynamic line features a flat trigger bow.

This is mainly a preference thing, so if you prefer the standard trigger bow, you can find the SSA and SSA-E HERE.

FAQ

Which is better? Curved or Flat?
One is not necessarily better than the other. It all comes down to personal preference. Just remember, the best trigger is the one you get out and train with. IYSYS.
