AR-15 Trigger

United Defense AR-15 Trigger

This is a replacement trigger from United Defense for the AR-15. It is for builders finishing a lower receiver, the lower half of the rifle that holds the fire control group, and for owners swapping out a worn or damaged trigger. It has the familiar curved blade and a black finish, so it looks at home in a standard rifle.

Features

• AR-15 Pattern Trigger — Shaped for the AR-15 fire control group, the trigger, hammer, disconnector and springs that release each shot.
• Curved Trigger Blade — The blade has the traditional curved profile that most AR-15 shooters already know.
• Black Finish — The black surface matches the receivers and controls on most AR-15 rifles.
• Trigger Pin Bore — A cross hole through the body lets the trigger pivot on the trigger pin that runs through the lower receiver.
• Integral Trigger Body — The blade and body are one piece, and the body carries the surfaces that hold the hammer and contact the safety selector.
• Bare Trigger Component — The photo shows the trigger alone, without hammer, disconnector or springs.
• United Defense Brand — It is made by a commercial manufacturer and is not a surplus-issue part.

Fit And Installation

The trigger goes into the lower receiver's fire control pocket and is held by the trigger pin. You will need your existing disconnector and springs, or new ones, to complete the group. After installation, function check the rifle by testing safe, fire and reset with the rifle unloaded. If you have not worked on a fire control group before, have a gunsmith fit it.
