If your AR-15 has a crisp trigger you installed yourself in a few minutes, you know why CMC Triggers matters. Its self-contained drop-in AR-15 trigger sold shooters on a simple idea: push two pins and you’re done. Today it makes single-stage and two-stage AR triggers, Glock flat triggers through Gen 6, AK triggers and triggers for the Ruger 10/22 and Remington rifles. Here is who they are, what they make, and what is worth buying.

Who CMC Triggers is

CMC Triggers Corp. is a family-owned Fort Worth, Texas company founded in 2003, best known for what it calls the Original Drop-In AR-15 trigger. CMC traces to champion shooter Chip McCormick, who sold the trigger business to the Biegel family in 2012.

There’s a tangle of names here that confuses people, so here it is straight. Michael “Chip” McCormick was a well-known competitive shooter and 1911 man. The Biegels bought the trigger company from him in 2012, and it has stayed in that family. Separately, Chip McCormick Custom, the 1911 magazine and parts company, went to Wilson Combat around the end of 2017. McCormick said he wanted to retire, and that there was no one he felt more comfortable selling to than Bill Wilson. The two had been friends since they met at a match in 1981. Both businesses trace back to the same man, but they’re different companies. So a “CMC” 1911 magazine in a listing may have nothing to do with this trigger company.

The current leader is Jennifer Biegel, who returned as CEO and president in July 2025. She joined the family business in 2010, left in 2021 to start a consulting firm and a Phoenix gun store, and came back. The group also includes San Tan Tactical and SOUSA Optics, which makes this a bigger operation than its trigger reputation suggests.

On the quality ladder, CMC is solid mid-tier. It isn’t the cheapest drop-in or the most prestigious, but it’s proven and fairly priced.

What CMC Triggers makes

AR-15 and AR-10 drop-in triggers

This is the core. The self-contained group comes in single-stage and two-stage versions, flat or curved, at preset pull weights. A flat single-stage drop-in was $174 at MidwayUSA and Optics Planet in our feed, across pull weights including 3.5 and 5.5 pounds. CMC’s cheaper Component and curved triggers start much lower, from $97.99 at Optics Planet for a small-pin curved 3.5-pound unit. Check the listing, because Component triggers don’t all share the housed drop-in design. Anti-walk pin kits are $13.50 and fit the same way.

Glock triggers and Kragos slides

CMC’s flat-faced Glock kits are $107.99 for the Gen 5 9mm guns at MidwayUSA and KYGUNCO. Its own site now lists a drop-in trigger for Glock Gen 5/6 9mm, without housing, at $93.74 on sale from $124.99. That’s worth knowing, since a lot of Glock parts stop at Gen 5. Retailers also carry Kragos RMR-cut slides for the Glock 17 and 19 Gen 3 at about $427.50, although CMC’s home page doesn’t feature them, so check stock.

AK, Ruger and Remington

The AK-47 drop-in is a single-stage in flat or Yella Jacket styles, from $129.92 at Shooting Surplus for a 3.5-pound flat and $169.99 at Battlehawk for lighter pulls. CMC also lists triggers for the Ruger 10/22 and Remington rifles.

Receivers and parts

CMC has quietly become more than a trigger shop. Its site lists a mil-spec AR-15 stripped lower, marked new at $74.99, and our feed shows CMC barrels, BCGs from about $160, gas parts, buffer tubes and lower parts kits. Most buyers still come for the trigger, and I’d shop the rest on price against bigger parts brands.

Build quality and the drop-in idea

Instead of a loose hammer, trigger, disconnector and springs that have to be fitted, CMC assembles everything into one housing at a preset pull weight. You get the same pull on every unit and far less chance of a bad install. CMC advertises a 100% satisfaction guarantee with a lifetime warranty, and says adjustments are handled by returning the trigger for repair or replacement. So don’t open it up and start filing. It’s made to be left alone.

One thing to think about before you order a light one: a light trigger is great at a bench and less forgiving under stress. A 3.5-pound single-stage is a nice all-round range choice, while a defensive rifle deserves a more careful look at a heavier pull. And always do a function check after installing any trigger: test safety, disconnector and reset with an empty, verified-clear rifle.

How CMC Triggers compares

The main rivals are Geissele, Timney, Rise Armament and LaRue. Geissele is the premium name for two-stage triggers. Timney is the other big drop-in brand, and Rise competes on value. CMC’s edge is the mix of a proven design and a fair price. Check the actual price, though: at $174, a flat CMC isn’t a bargain-bin trigger, and watching for sales pays off. Its own site was running marked-down prices when I checked. If you want the best-regarded two-stage feel and price doesn’t matter, buy a Geissele. If you want a clean upgrade you can install at the kitchen table, CMC makes sense.

Who should buy what

• First-time AR upgrader: a 3.5-pound single-stage flat.
• Competition shooter: a lighter single-stage or a two-stage.
• Defensive rifle owner: a heavier pull, such as the 5.5-pound flat.
• Glock owner: a flat kit for your exact generation.
• AK shooter: the AK drop-in, which is a big step up from a gritty factory pull.
• Lower builder: a stripped lower and matching trigger, priced against rivals.

The CMC philosophy

CMC takes something that used to need a gunsmith and makes it hard to get wrong. Every part is fitted and set before it reaches you. That removes the skill barrier and most of the risk of a bad install, and it’s why self-contained triggers took over the market. The same thinking runs through the Glock and AK kits: a meaningful upgrade an ordinary owner can do at home.

How to choose your CMC setup

Start with the platform and the job. On an AR, check your lower first, because small-pin and large-pin versions differ, and most standard AR-15 lowers use small pins. Pick flat or curved by feel. The flat face gives your finger a consistent spot, and the curve feels traditional. Then choose your pull weight honestly for how you use the rifle. Glock owners should match the kit to the generation and caliber, since the listings split Gen 3, 4, 5 and 6 and separate 9mm from .40. If it’s a Gen 6, stick with the kit that names it.

The upgrade that became the default

It’s easy to forget what AR trigger upgrades used to be like: loose match parts, careful fitting and maybe a gunsmith bill. Today “drop-in trigger” is a whole category that every major maker competes in. CMC’s claim to the word “original” is printed on its own product line, and it has earned a long run on the strength of it. A Texas family has now run the trigger business for well over a decade, long after the man whose initials are on it moved on to retirement.
