What is a drop-in AR-15 trigger?

A drop-in AR-15 trigger is a self-contained trigger module that can be installed into a lower receiver without needing to assemble individual parts. It's designed for faster installation and more consistent performance.

Are drop-in triggers better than mil-spec?

Yes, drop-in triggers usually offer a much cleaner break, reduced pull weight, and faster reset compared to standard mil-spec triggers. They’re ideal for upgrades, precision shooting, and competition use.

Do I need special tools to install a drop-in trigger?

Most drop-in AR-15 triggers can be installed with basic tools such as punches and a small hammer. Anti-walk pins may be required for some models.

What's the difference between single-stage and two-stage triggers?

Single-stage triggers offer a consistent pull and are great for fast shooting. Two-stage triggers provide an initial light take-up followed by a crisp break, ideal for precision shooting and long-range control.
