Product Overview

Building an AR-15 from the ground up doesn't have to mean hunting down parts one by one. The ALG Defense AR-15 Lower Parts Kit with ACT Trigger delivers everything you need to complete your lower receiver in a single package. Whether you're assembling a precision rifle, upgrading an existing build, or putting together a reliable field gun, this kit bundles all the small but critical components that make your AR function—plus ALG's respected ACT trigger to give you a clean, predictable break right out of the box.

This is purpose-built for shooters who want to skip the parts-chasing phase and get to the range or field faster. ALG Defense has earned a solid reputation among AR builders for no-nonsense, reliable triggers and quality control, and this kit reflects that philosophy. You get the trigger and every detent, spring, pin, and lever needed to complete the job without having to cross-reference a dozen vendor websites. The modular design means you can pair it with any receiver and furniture to match your shooting style.

If you already have a grip you prefer or want to source one separately, ALG offers this kit with or without one—so you can build exactly what you need without paying for duplicates.

Frequently Asked Questions

What do I still need to complete my AR-15 lower receiver?

This kit includes all the internal parts and trigger. You'll still need the stripped lower receiver itself, and optionally a grip if you choose the no-grip version of the kit.

What is the ACT trigger, and how does it perform?

The ACT is ALG Defense's Advanced Combat Trigger. We don't have specific pull weight or technical specs in our system, but ALG is known for producing reliable, field-proven triggers. Contact our team for detailed performance specs if you have specific requirements.

Can I use this kit with any AR-15 lower receiver?

Yes. This is a standard AR-15 pattern lower parts kit and will work with any mil-spec or commercial AR-15 lower receiver.

Does this kit come with a grip?

This kit is available both with and without a grip. Choose the option that matches your build plan or existing grip preference.
