Frequently Asked Questions

What comes in an AR-15 lower parts kit?

A lower parts kit includes the internal fire control components that go into a stripped AR-15 lower receiver: the trigger group, hammer, springs, pins, and related small parts. You'll still need to source the lower receiver itself separately.

Is this kit compatible with all AR-15 lowers?

The Tapco TAP22037 is designed for standard AR-15 lower receivers. Always verify compatibility with your specific receiver before ordering if you have a non-standard or proprietary platform.

Do I need gunsmithing experience to assemble a lower parts kit?

Lower parts assembly requires care and attention to detail—proper pin placement, spring orientation, and hammer/trigger geometry are critical to safe function. If you're new to AR builds, consult a detailed build guide or have an experienced builder walk you through the process.
