Lantac E-ct1 3.5lb Ss Str Trigger

The Lantac E-CT1 3.5lb straight trigger brings match-grade precision to your AR-platform rifle without the guesswork. Built for shooters who demand a crisp, predictable break and minimal reset—whether you're running a precision rifle at distance, competing on the clock, or hunting from a cold barrel—this single-stage trigger is engineered to tighten your shot groups and speed your splits. Lantac's proprietary sear manufacturing process and entirely redesigned internal geometry deliver the kind of reliability and feel you get from triggers that cost twice as much.

What sets the E-CT1 apart is the attention to manufacturing fundamentals. The hammer and trigger disconnector are machined from S7 tool steel and case hardened before receiving a Black Oxide finish—the same process aerospace manufacturers use to ensure zero drift and maximum durability. The CNC-machined aluminum cassette accepts either standard AR pins or threaded screw-type pins, and includes adjustment set screws so you can dial in perfect pin tension without guesswork. Every unit is built to AS9100 aerospace standards and inspected with precision equipment before it ships.

The E-CT1 comes in both hybrid curve and flat bow designs, so you can choose the bow geometry that fits your trigger finger and shooting style. Installation is straightforward on any standard AR receiver chambered in 5.56/.223 or 7.62/.308. You get the complete trigger assembly and pin set ready to go.

Frequently Asked Questions

What AR platforms and calibers does the E-CT1 work with?

The E-CT1 is designed for AR-15 and AR-10 receivers chambered in 5.56/.223 or 7.62/.308. It installs using standard AR trigger pins or optional threaded screw-type pins.

What's the difference between the hybrid curve and flat bow designs?

Both designs use the same precision sear geometry and 3.5lb pull weight. The choice between hybrid curve and flat bow comes down to personal preference and how your finger naturally contacts the trigger—hybrid curve offers a subtle radius, while flat bow is straightforward. Either way, you get the same crisp break and fast reset.

Can I adjust the trigger pull weight after installation?

The E-CT1 cassette includes adjustment set screws that allow you to dial in perfect pin tension. This fine-tunes the feel and performance without changing the 3.5lb pull weight specification.

What's included in the box?

You get the complete trigger assembly and a pin set ready for installation. No additional parts are needed for a standard AR build.
