Performance-grade AR triggers that drop in for instant, better accuracy.

If you're ready to take your AR build to the next level, the first thing you should upgrade is that mil-spec trigger. While it provides consistent performance, its take-up, creep, and over-travel often leave more to be desired. It makes sense to upgrade that factory trigger while you install your lower parts kit for the first time. Drop-in triggers are preassembled and literally "drop in" to the receiver using factory pins if pins are not provided.

Why a Drop-in Trigger Upgrade?

The factory AR trigger can feel a loose gritty and loose. This often means less-than-ideal shot placement and poorer accuracy than is possible with that shiny, new upper assembly. Drop-in triggers take just a few minutes to install. If you're building your lower for the first time, a drop-in trigger makes assembly easier: The hammer, trigger, disconnect, and sear are built into the trigger housing. All you do is seat it and pin it!

Triggers from PSA, ALG, Rise Armament, Bravo Co., and More

We've worked closely with top AR parts makers to provide the best "bang for your buck" (literally) when it comes to a decent AR trigger. With options like PSA's custom Match Trigger, Rise Armament's LE Series, and Bravo Company's nickel trigger assemblies, you'll find something that fits your receiver's needs without burning a hole in your wallet.

"How do I install my new trigger?"

Installing a drop-in trigger is easier than assembling your factory lower parts kit's included hammer and trigger. If you're about to finish your new lower, give it a pause and grab your upgraded trigger from the options above. If you've already installed your LPK and want to upgrade even still, simply remove your existing hammer and trigger pins, then remove all components that come loose. Drop your new trigger in, and replace your pins. Easy.
