Product Overview

The Lantac M-SPEC Lower Parts Kit is a complete, domestic-made component set designed for AR15 platform rifles. Whether you're building a rifle from a stripped lower receiver or restocking spare parts, this LPK bundles every small component you need to assemble a functioning lower—no trips back to the parts bin mid-build. Lantac manufactures to military specification standards, so you're getting parts engineered for durability and compliance, not bargain-bin compromises.

This kit covers the takedown and pivot pins, all detents and springs, ambidextrous safety selector, bolt catch assembly, and magazine catch hardware. If you're working with a Lantac Aero lower or other quality receiver, the mag catch set screw is 6-32 compatible and comes with the hex key you need. It's the kind of kit that lets you focus on the build instead of hunting through your spare parts drawer or waiting for backorders on individual components.

Made in the USA and backed by a lifetime warranty, the M-SPEC LPK is built for shooters, hunters, and builders who expect their AR parts to work the first time and stay reliable through years of hunting season, range trips, and field use. All hardware is engineered to current military spec materials, heat treatment, and finishes—the kind of attention that matters when you're counting on your rifle in the field.

Frequently Asked Questions

Will this lower parts kit work with my AR15 lower receiver?

The Lantac M-SPEC LPK is designed for AR15 style rifles. It is confirmed compatible with Lantac Aero lowers and other quality AR15 receivers. If you have a specific lower in mind, verify that it accepts standard AR15 components.

What's included in this kit?

Everything you need to assemble a functioning lower: both pivot and takedown pins, all detents and springs, the ambidextrous safety selector, complete bolt catch assembly with springs and hardware, magazine catch assembly, and a 1/16th hex key for the mag catch set screw.

Is the safety selector truly ambidextrous?

Yes. The kit includes an ambidextrous safety selector, meaning it operates from both sides of the receiver for left and right-handed shooters.

Are there any tools I need to assemble this kit?

The 1/16th hex key for the mag catch set screw is included. Depending on your lower and build approach, you may need standard gunsmith tools, but the critical hardware for this kit is covered.
