LBE Unlimited AR2STG Adjustable Two-Stage Curved Trigger Group for AR-15

The LBE Unlimited AR2STG is a drop-in two-stage trigger group built for AR-15 rifles and carbines. If you're upgrading a build or refreshing a rifle that's spent years at the range, this curved trigger delivers a smoother, more controllable break than milspec without requiring gunsmithing. LBE Unlimited engineered the AR2STG with a self-centering disconnector and precision-ground working parts to keep the pull clean and predictable across the full range of 4.2–4.6 pounds—the kind of measured take-up and release you want whether you're running precision drills or hunting.

Installation is straightforward: the trigger fits .154" pins and drops into a standard AR-15 lower receiver without modification. All critical components are heat-treated and case-hardened, so you're not trading durability for a lighter, crisper trigger. This is a practical upgrade for shooters who want to tighten their groups and improve trigger control without the cost and complexity of a full-custom job.

LBE Unlimited has built a reputation on honest, no-nonsense AR parts. The AR2STG reflects that philosophy—high-quality manufacturing, solid metallurgy, and real-world performance that justifies its place in a rifle you actually shoot.

Frequently Asked Questions

Will the AR2STG fit my AR-15 lower receiver?

Yes. The AR2STG is designed for standard AR-15 platforms and uses .154" trigger pins. It drops in without modification to any compatible AR-15 lower.

What's the difference between a two-stage trigger and a standard milspec trigger?

A two-stage trigger has a take-up phase before the break—you feel the first stage before the trigger breaks. This design can improve control and accuracy by giving you a clearer, more predictable release point. The AR2STG's self-centering disconnector and precision-ground parts ensure that this two-stage feel is smooth and consistent.

Is this trigger suitable for hunting and general shooting?

Yes. The AR2STG's 4.2–4.6 lb. pull and smooth two-stage break make it well-suited for hunting, target shooting, and range work where improved trigger control and consistency matter.

Does installation require a gunsmith?

No. The AR2STG is a drop-in trigger group designed for easy assembly in any standard AR-15 lower receiver. No modifications or special tools are required.
