Geissele triggers are the most widely used aftermarket trigger in U.S. military and law enforcement service — and the correct choice for any URGI, Super Duty, or HRT clone build. Charlie's Custom Clones carries the full Geissele trigger lineup including the SSA (Super Semi-Automatic), SSA-E (Enhanced), SD-E (Super Dynamic Enhanced), Hi-Speed, and rare mil-contract variants issued to USASOC and FBI units.
The Geissele SSA is a two-stage, mil-spec inspired trigger used extensively in USASOC M4A1 builds. The SSA-E improves on it with a lighter and crisper second stage. The SD-E is optimized for rapid semi-auto fire. Browse the full selection below — color variants including Black, DDC, and limited production runs are noted in each listing.
