At CMC Triggers we get asked all the time what the difference is between a single stage and a two stage trigger. Well, let’s simplify things and get that question answered! Whether single stage or two stage, upgrading your AR15/AR10 trigger is a big step toward better accuracy. CMC Triggers manufactures light/crisp triggers that are designed to operate safely and reliably. Our sear engagement surfaces overlap 6-8 times greater than standard triggers making them significantly safer by comparison.

Single stage triggers are the most common type of AR-15 trigger on the market. The vast majority of rifles sold on the civilian market come equipped with a basic mil-spec-ish single stage trigger. That doesn’t mean that the single stage is bad. There are many precision and hunting rifles on the market with this type of trigger. The benefit of a single stage trigger is that it’s simple! A single stage trigger requires one range of motion to pull the trigger in order to release the hammer. There is no slack during the take-up as the full weight of the trigger is already resting on the spring and sear. To fire, the shooter simply overcomes the trigger pull weight. Single stage triggers are popular due to their quick operation and simple design and the majority of shooters prefer a single stage trigger for most applications. A good shooter, with practice, can shoot slightly faster with a single stage trigger.

At CMC Triggers We offer AR15/AR10 single stage triggers in the following trigger pull weights: 2.5lb (competition), 3.5lb, 4.5lb, 5.5lb & 6.5 Lbs. Available in the CMC Flat signature patented bow design, Standard Curved Bow and Combat Curved Trigger hybrid bow (CCT®).

Two stage triggers require the shooter to pull the trigger until it hits a “break wall”, which is a stopping point between the first and second stages. Similar to taking up the slack as some people call it, the two stage trigger then breaks during the second stage after hitting the break wall. The benefit of a two stage trigger is that the shooter knows at exactly what point the trigger will break and is usually preferred on a DMR or marksman style bench-rest rifle. The total weight of the trigger is the sum of both portions of the trigger pull. For instance, a 4lb trigger might have a light 2lb uptake followed by an additional 2lb “wall.” This provides a bit of safety slack for the rifle to be bumped around as well as a very predictable breakpoint for the shot. Another benefit of the two-stage trigger is the ability to “prep” it. The shooter takes the initial slack out of the trigger or first stage. Once ready for the shot, the shooter only needs to gently pull past the remaining wall to fire.

We offer AR15/AR10 two stage triggers in the following trigger pull weights:

  • 1lb&3lb
  • 2lb&2lb
  • 2lb&3lb
  • 2lb&4lb
  • 2lb&5lb

The decision is purely personal preference but it’s important when choosing between single-stage and two-stage triggers, to determine what you want from the weapon. The single-stage triggers work well for those who require fast action pull with reliable performance, while the two-stage triggers are effective for target practice and applications that require more precision. Regardless of which type you chose, you must further select an appropriate weight for your shooting style. More important than the type selected is that you practice with your new trigger.

CMC Triggers is the original manufacturer of the Drop-in Trigger Group for the AR-15/10 rifle since 2003. CMC’s critical sear engagement surfaces have a proprietary machining process that renders superior surface finish and dimensional control. As compared to their competition, the techniques used to establish a 1-2 RMS surface finish as opposed to EDMing which leaves a pitty 32 RMS, compared to a mirror which is 0 RMS. All CMC triggers come with CMC Anti-Walk Pin Set. All CMC products come with 100% Satisfaction Guarantee and Lifetime Warranty.
