Frequently Asked Questions (FAQ)

What is the “DDC” finish I see on many Geissele parts?

DDC stands for Desert Dirt Color. It is a unique, high-durability anodized finish. Because of the nature of the anodizing process, DDC shades can vary slightly from part to part—a feature that many shooters love for its professional “custom” look.

Can I install Geissele triggers myself?

Yes. Geissele triggers are designed as “drop-in” parts for any Mil-Spec AR-15 lower receiver. Most installations take less than 10 minutes with a standard punch set.
