Upgrading your build with a quality trigger has never been easier than with the LANTAC E-CT1. The trigger is packaged in a lightweight, yet durable aluminum cassette, allowing it to simply be dropped into your favorite lower receiver. Unlike many drop-in triggers, the E-CT1 does NOT require captive or anti-rotation trigger pins, as it features adjustment set screws built into the chassis allowing shooters to get the perfect amount of pin tension. This drop-in aluminum chassis has been finished with a high quality black hardcoat anodized finish, and then laser engraved.

The chassis is only half the story, however.

The heart of the E-CT1 is the S7 Tool steel trigger bow, hammer, and disconnector. With fully redesigned internal geometry and a proprietary sear manufacturing process, the E-CT1 AR-15 trigger offers shooters an insanely short trigger reset, allowing for blazing quick split times to get the edge over the competition. The fixed 3.5lb trigger also has very minimal over-travel and a fantastically crisp break, giving you not just speed, but a predictable and consistent pull that will help you land those longer-range hits easier than ever before. This trigger features a flat bow, providing consistent finger positioning and increased leverage. With the perfect combination of slick-styling and top-tier performance, the LANTAC USA E-CT1 is the perfect trigger for your next build.

LANTAC USA manufactures and produces some of the highest quality AR-15 components, accessories, and rifles available on the market today. Each component is made right here in the U.S.A. utilizing the latest tools and techniques to rigid standards.

Double taps and distance precision all in one trigger


I purchased this trigger about a year ago on an amazing sale. I waited to review it because I wanted to really give it some use. This has been in my primary and now only AR15 rifle for that entire year. It has seen about 300 unsuppressed rounds and about the same with a suppressor.(I know not that much, it was a busy year so didn't get the trigger time I'd have liked to) It functioned flawlessly the entire time and always broke when expected. My groups tighted up considerably after installing this trigger and follow up shot time was cut in half. I have used most triggers out there and this is the only one I'd ever chose if I decided to build another AR after working down to one. Fast installation, light predictable pull, fast short reset, and a high quality fit n finish. You can't really ask for more.

Nice Drop In


Picked this up over a year ago now on a steal of a deal (Thanks PA). Very nice trigger, Durable flat bow, nice pull with short reset. Fit, function and reliability, are good. No failures. Skeletonized to fit this particular build and add a bit of character. At teh price I paid, I'm happy with my purchase and recommend this trigger.
