LANTAC E-CT1 3.5lb Single-Stage Flat Trigger for AR-15 / AR-10

Description

The LANTAC E-CT1 is the evolution of Lantac's original curved trigger, redesigned from the sear surfaces on out. The flat-bow shoe gives your trigger finger a longer reach and more leverage, and the 3.5 lb single-stage pull breaks clean with almost no creep. It's the kind of upgrade you feel on the very first shot, whether you're running a duty rifle or chasing faster split times at a match.

What Makes the E-CT1 Break So Clean

The hammer, trigger, and disconnector are precision machined from S7 tool steel using a proprietary sear process, then case hardened and given a black oxide finish for the long haul. The internal geometry was completely reworked to deliver a short reset and near non-existent overtravel, so the reset is quick and positive under your finger. The trigger mechanism is built by Timney and the whole assembly is manufactured to AS9100 aerospace standards, which tells you plenty about the tolerances involved.

Dropping the E-CT1 Into Your Lower

Everything lives in a CNC-machined aluminum cassette finished in hard-coat anodize, so it drops straight into your lower receiver as a single self-contained unit. Unlike a lot of drop-in triggers, the E-CT1 doesn't require captive or anti-rotation pins. It has adjustment set screws built into the chassis that let you dial in perfect pin tension, and you can run it with standard pins or the included threaded hardware. Install is quick and beginner-friendly.

Where the E-CT1 Fits

This one is designed for AR receivers chambered in 5.56/.223 or 7.62/.308, so it covers both AR-15 and AR-10 pattern builds. It's a fixed 3.5 lb weight, which lands in a sweet spot that works for competition, range work, and a well-tuned defensive rifle. If you've been running a gritty mil-spec trigger, this is one of the first upgrades that genuinely changes how your rifle shoots.
