How to Replace a AR Trigger | Timney Triggers | Tactical Rifleman

Some people ask why you might want to change the trigger in your AR.  I explain that with trigger control being one of the important fundamentals of shooting and that a standard AR has an two stage trigger with 5-8 lb pull, you might want to change that stock trigger to help you improve your trigger control.  

In this video I show you how to replace the stock trigger with a Timney 667s.  This is a single stage trigger that is set to break at 3 lbs.  I like Timney because this is a one piece unit that is simple to install along with having a crisp clean break every time at 3lbs.  Timney has been building great rifle triggers for over 60 years. 

When exploring the different triggers, it’s important to find a product that is right for you and your needs.   Here are the main differences between the two-stage and the single-stage replacement triggers.

What are Single-Stage Triggers?

Single-stage triggers are the traditional product for the avid user. They’re designed to operate in one smooth range of motion allowing you to pull the trigger through to release the pin. It’s simple and there are no gimmicks involved in the use of single-stage triggers. Many find single-stage triggers easier to adjust and with a clean break in the trigger action.

What are Two-Stage Triggers?

Two-stage triggers have an operating process that involves two distinct phases of firing. The advantage of this style of design is that it allows the user to know exactly when the firing will take place. They know that once they set the trigger after the first phase, the gun will fire. Instead of breaking and firing as part of one process, you hit a break wall within the firing of the weapon. Immediately following this break wall, the weapon discharges. Knowing when the trigger is going to break gives you the advantage in terms of accuracy over your target. You’ll be able to time your shots more effectively, and mitigate issues with balance and unsteady grips that can limit some weapons.

How to Choose Between the Two

In choosing between single-stage replacement triggers and two-stage triggers, it’s important to determine what you want from the weapon. The single-stage triggers work well for those who require a fast action pull with reliable performance, while the two-stage triggers are effective for target practice in high stress scenarios.
