Outerwild Outpost AR-15 Lower Parts Kit – No Trigger Guard, No Grip

100% Made in America

The Outerwild Outpost AR-15 Lower Parts Kit – No Trigger Guard, No Grip is the perfect choice for custom AR builders who want high-quality, American-made components and the freedom to select their own furniture. Whether you’re upgrading an existing rifle or building a new lower from scratch, this kit delivers the essential Mil-Spec internals you need—without the parts you plan to replace.

Each component is precision machined and manufactured to exacting Mil-Spec standards to ensure proper fit, flawless function, and long-term reliability. Unlike many mass-market kits, Outerwild Outpost does not use polymer or MIM components—only high-strength materials designed to withstand hard use in the field or at the range.

This kit includes the complete Fire Control Group (FCG), so you’re covered on performance-critical parts, but leaves out the grip and trigger guard, giving you the flexibility to install aftermarket options of your choice. If you prefer a fully populated kit, check out our Complete AR-15 Lower Parts Kit. Or, if you’re going ultra-custom and don’t need the FCG, take a look at our stripped AR-15 LPK.
