Description
Sometimes you just need a solid, no-nonsense trigger that does exactly what it's supposed to. The LBE Unlimited AR-15 Mil-Spec Replacement Trigger Group is that part. It's a full set of GI-style fire control components built to standard military specifications, giving you a familiar curved trigger bow and the dependable break that generations of AR shooters have run without a second thought.
What Comes in the LBE Unlimited Trigger Group
This is a complete kit, not just a trigger shoe. You get the trigger, hammer, disconnector, hammer spring, trigger spring, disconnector spring, trigger pin, and hammer pin. That means everything needed to fill out a bare lower or swap out a worn set of internals in one go. The full-power springs are there for a reason too, giving you reliable primer ignition round after round. Pull weight lands in the standard mil-spec range of roughly 5.5 to 8.5 pounds, which is right where a classic GI trigger should be.
Built to Spec and Made in the USA
The components are heat-treated hardened steel with a matte black finish, machined to hold up to real range time and rougher conditions. Fit and finish on these tends to be clean, with a crisp break once installed. It's a true drop-back-to-factory setup, so there's no guesswork on compatibility with standard AR-15 lower receivers.
A Practical Pick for Builders and Armorer Work
This group makes a lot of sense as a spare in your parts bin, the foundation of a budget build, or a straightforward fix when an old fire control group starts feeling gritty. If you enjoy the challenge of running iron-clad basics and sharpening your marksmanship on a traditional trigger, this is a reliable, wallet-friendly way to get there. LBE Unlimited has built a reputation on turning out honest, hardworking gun parts, and this trigger group fits that mold perfectly.

Frequently Asked Questions
What's the pull weight on the LBE Unlimited mil-spec trigger group?
It sits in the standard mil-spec range of about 5.5 to 8.5 pounds. That's typical for a GI-style trigger and gives you a consistent, dependable break. It won't feel like a light target trigger, but that's by design for reliability.
Does this trigger group include everything I need to complete a lower?
For the fire control side, yes. You get the trigger, hammer, disconnector, all three springs, and both pins. It covers the trigger group portion of a build, though a full lower parts kit would also include items like the safety selector, bolt catch, and grip.
Will this LBE Unlimited trigger group fit a standard AR-15 lower?
It's built to military specifications and designed to drop into any standard AR-15 lower receiver. If your lower is mil-spec, this group is a direct fit. It uses standard pins for a straightforward install.
Is this a drop-in cassette-style trigger or individual components?
This is a traditional component-style fire control group, not a self-contained drop-in cassette. You'll install each piece individually into the lower using the included pins. It's the classic setup that's been standard on AR-15 rifles for decades.
