Geissele Super Dynamic Combat (SD-C) Trigger – AR-15/AR-10

The Geissele Super Dynamic Combat (SD-C) is a two-stage trigger designed for shooters who demand precision and speed in both competitive and defensive applications. This trigger delivers a clean, consistent break with minimal overtravel, allowing faster follow-up shots while maintaining the control of a two-stage design. The SD-C is built to withstand high round counts and harsh conditions, making it a reliable upgrade for serious AR platform users who need a trigger that performs when it matters.

Machined from tool steel with a proprietary hardening process, the SD-C features a corrosion-resistant finish and is built to mil-spec dimensions for compatibility with standard AR-15 and AR-10 lower receivers. Installation is straightforward for those familiar with AR trigger group removal and requires basic armorer tools. The trigger includes all necessary pins and springs.
