TacFire® USA-Made AR-15 Lower Receiver Parts Kit - Complete Small Parts Kit, Single-Stage Fire Control Group, Less Pistol Grip, Mil-Spec Steel Construction, Black Finish - LPKUSA-NG / 811261027534
Product Description
When building a custom AR-15, buying a standard lower parts kit often leaves you paying extra for a basic plastic A2 pistol grip that immediately gets tossed into a spare parts bin. Modern rifle builders almost always prefer choosing an aftermarket ergonomic grip that fits their hand size and angle preference. The **TacFire® AR-15 Lower Parts Kit / No Grip Included (Made in the USA) (LPKUSA-NG / 811261027534)** eliminates that wasted component, delivering a complete set of USA-manufactured lower receiver small parts and a fire control group without forcing you to pay for an unwanted factory grip.
Manufactured entirely in the United States to strict mil-spec tolerances, the LPKUSA-NG kit includes everything you need to finish a stripped AR-15 lower receiver except the pistol grip. You get a clean single-stage trigger and hammer assembly, takedown and pivot pins, mag catch assembly, bolt catch assembly, safety selector, buffer retainer, trigger guard, and all necessary detents and springs. Made from heat-treated carbon steel with black oxide and manganese phosphate protective finishes, these parts ensure crisp trigger breaks, smooth pin installation, and reliable mechanical operation.
Designed for universal fitment across all standard forged and billet mil-spec AR-15 lower receivers, this USA-made lower parts kit provides everything needed to complete your lower receiver build directly from your workbench.
*Armorer Bench Notes & Real-World Staging Guidance: The TacFire LPKUSA-NG kit arrives organized with all small pins, springs, and detents ready for assembly. LOWER RECEIVER COMPATIBILITY MATRIX: Fits all standard **mil-spec forged and billet AR-15 lower receivers** (.223 Rem / 5.56 NATO, 300 AAC Blackout, 6.5 Grendel, etc.). *Grip Note:* Requires a standard AR-15 pistol grip and grip screw/washer (sold separately). Workbench Setup Steps: 1. Organize small parts into small bench trays by sub-assembly (bolt catch, mag catch, pivot/takedown pins, fire control group). 2. Install the mag catch assembly and bolt catch roll pin using appropriate roll pin punches and bench blocks. 3. Install the front pivot pin and detent, using a pivot pin tool to keep the small detent spring from flying across the room. 4. Lubricate and install the single-stage trigger, disconnector, and hammer using the included trigger pins. 5. Install the safety selector, insert your chosen pistol grip with its detent and spring, and verify proper mechanical safety function before attaching an upper receiver.*
