The CMC Triggers AR-15 Component trigger with 4.5 lb pull weight gives you precision trigger control without committing to a full drop-in assembly. Built on the same proven engineering as CMC's drop-in line, this component trigger strips away the housing and lets you integrate a refined trigger mechanism into your existing AR platform receiver. It's engineered for shooters who want a cleaner, crisper break and positive reset in a customizable package.

Installation is straightforward for anyone comfortable working inside an AR receiver. The combat curved trigger face delivers a natural finger position and consistent engagement, while the 4.5 lb pull weight strikes a balance between control and speed—suitable for duty, sport, and hunting applications. The small pin design confirms compatibility with standard AR-15 platforms, so you're not locked into proprietary parts.

Whether you're building a precision rifle, tuning a duty gun, or refreshing the trigger on an existing upper, this component trigger works as a foundation for the exact trigger pull and feel you want. CMC's reputation for consistency and reliability carries through to this trigger mechanism, giving you confidence in repetitive performance at the range or in the field.

Frequently Asked Questions

Will this trigger fit my AR-15?

Yes, the small pin design is compatible with standard AR-15 and AR platform receivers. Confirm your receiver uses small pin holes; large pin (M16) receivers require a different trigger.

What does "component trigger" mean, and what do I need to install it?

A component trigger is the trigger mechanism alone—it does not include the drop-in housing. You'll install it directly into your AR receiver's trigger group cavity. You'll need basic AR gunsmithing tools and familiarity with trigger assembly. A CMC patented assembly tool can simplify installation but is sold separately.

What's the pull weight, and is it good for hunting or competition?

The 4.5 lb pull weight offers a middle ground between control and speed. It's versatile enough for duty rifles, hunting, and sport shooting, though your preference may depend on your specific use case and shooting style.

Is this a drop-in trigger?

No. This is a component trigger without a drop-in housing. If you want a plug-and-play drop-in option, CMC makes a separate Drop-in Trigger line. The component trigger requires installation into your receiver's trigger group.
