CMC Triggers AR-15 Pro

Best AR 15 Trigger

Smooth AR 15 trigger pulling ensures secure and accurate shooting, necessary for tactical and competition shooters. The trigger is an important firearm part, which provides a hitting-the-target mission. The majority of triggers are single-action (mechanically the simplest kind), which disconnect a sear that releases in its turn a spring-tension hammer.

Why do we need AR 15 trigger?

The smoother trigger, the more precise firing. Upgraded AR 15 triggers should deliver for the rifles a light pull, safe position, and short crisp reset to enhance performance and faster shooting rate in combat, competition shooting, training, or plinking on the range. Dependable new triggers allow remarkable upgrading of any AR rifle, enhancing the performance of pulling, reset, lock time, and delivering safety (while holding the trigger).

FAQ

How does a two-stage trigger work?
Two-stage triggers feature such a working process, which consists of two distinct phases of shooting. Such a trigger design allows the shooter to control the firing start for sure. The firearm will fire after setting the trigger and passing the first phase.
What is the influence of the trigger pull?
Trigger Pull shows how many force pounds should be applied to pull the trigger. If the trigger is hard to pull, it can cause less precise shots, meanwhile, the lightweight pull can result in accidental discharges if the shooter isn’t careful.
How does an AR 15 trigger work?
The trigger is a 2-stage small device, releasing a catch (or spring) to activate a shooting mechanism. The trigger is equipped with sear hooks and a built-in disconnector.

The trigger starts operating after its release: it turns, helping the disconnector turn out, the hammer go and drop onto the trigger sear hooks.

What is the trigger pull on an AR 15?
According to the mil-spec requirement for the trigger pull on the AR-15, the trigger pulls weight should be from 5.5 to 8.5 pounds. Not all AR-15 are completed with Mil-spec triggers, so trigger pull can be even 2.5 pounds.
Should I upgrade my AR 15 trigger?
The trigger modernization allows enhancing firing accuracy. That’s why it makes sense to install a better reliable trigger without high expenses.

Conclusion

Choose triggers with well-polished surfaces of sear and hammer, which are involved in pulling action for sleeking the trigger up, ensuring proper performance. Follow the manufacturer’s guides while installing or any modernization not to void the warranty. At times after squeezing the trigger, the rifle can be pulled off the target, because of the incorrect trigger pull weight. Be aware sometimes advertised ones can differ from really tested trigger pull weights.
