Description
If you have ever fought a gritty, spongy mil-spec trigger while trying to hold a tight group, the CMC 93502 fixes that in about five minutes of bench time. This is CMC's two-stage curved drop-in unit for the AR-15 and AR-10, factory-tuned to roughly a 2-pound take-up with a 4-pound release. The whole assembly lives inside a sealed housing, so the hammer, sear, disconnector, and springs stay protected from carbon and grit that normally collect in an open lower.
What Sets the CMC 93502 Apart
The curved bow gives you that traditional finger feel most folks grew up with, and the two-stage design lets you take up the slack, feel the wall, then break the shot clean. There is no creep before the hammer drops and no grittiness through the pull, which is exactly what you want for precision work or a designated marksman build. CMC machines the engagement surfaces to tight tolerances and builds the trigger and sear from S7 tool steel inside an alloy steel housing, so it holds up over a long service life. A rocket wire hammer spring keeps lock time short and reliable with commercial or military grade ammo.
Dropping the 93502 Into Your Build
Installation is about as painless as it gets. You separate the upper from the lower, set the one-piece unit into the trigger pocket, slide the supplied oversized pins through, and snug the retaining screws. Keep in mind this is the small pin (.154) version, which fits the vast majority of AR lowers built after 2009 and any non-Colt receiver.
The pull is preset at the factory and not user adjustable, which is a good thing here since you get a consistent, repeatable break every time without fiddling with tension screws. It is a straightforward way to make an accurate rifle shoot even better, and it is proudly made in Texas.

Frequently Asked Questions
Will the CMC 93502 fit my AR-15 lower?
This is the small pin version with a .154 pin diameter, which fits standard mil-spec receivers and any non-Colt AR built after 2009. If you have a Colt made between 1991 and late 2009, you likely need the large pin (.172) version instead. It also does not fit Colt rifles equipped with a sear block, so check your lower before ordering.
How hard is the 93502 to install?
It is one of the easier upgrades you can do to an AR. You split the upper and lower, drop the one-piece unit into the trigger pocket, push the supplied pins through, and tighten the retaining screws. Most people have it done in a few minutes with basic hand tools, and there is no fitting or tuning required.
What does the 2 lb / 4 lb pull weight actually feel like?
The two-stage design means you take up a light first stage of around 2 pounds, hit a defined wall, then break the shot at about 4 pounds total. That staged feel is great for precision shooting because it gives you a tactile warning right before the hammer drops. The break is crisp with no creep or grittiness.
Can I adjust the pull weight on the CMC 93502?
No, this trigger is preset at the factory and is not user adjustable. That is by design and it keeps the break consistent and repeatable shot after shot. If you want a different weight, CMC offers this same two-stage curved unit in other pull weight configurations.
