Sons Of Liberty Gun Works Blaster Guts - Premium SOLGW BG Blaster Guts Kit

The Sons of Liberty Gun Works Blaster Guts kit is a complete small-parts solution for builders and gunsmiths assembling or refreshing mil-spec AR-platform rifles. Whether you're putting together a competition gun, a duty rifle, or a reliable defensive carbine, this kit consolidates the internal hardware you need—trigger group parts, safety controls, magazine catch, and bolt catch assembly—so you're not hunting down components from multiple suppliers.

SOLGW has built a reputation on no-nonsense quality, and the Blaster Guts kit reflects that philosophy. The kit includes mil-spec cast components where appropriate, QPQ-finished steel pins and detents for durability, and springs and buffers engineered to function reliably in hard use. If you're familiar with mil-spec ARs and you know what you're doing at the workbench, these parts play well with standard receivers and fire control groups. The kit consolidates a significant portion of the small-parts burden, leaving you free to focus on upper assembly, furniture, and fit.

This kit works for DIY builders, armorer-level tinkerers, and anyone restocking spares for multiple guns. Because SOLGW manufactures rather than rebrand, you're getting parts with real design intent behind them, not generic commodity hardware. It's the kind of thing you grab when you want to know exactly what's going into your gun and you trust the maker.

Frequently Asked Questions

Will the Blaster Guts kit work with my AR-15 build?

The kit is designed for mil-spec AR-platform firearms. If your receiver and other components are mil-spec standard, these parts should fit. When in doubt, verify with your receiver manufacturer or consult an experienced builder before final assembly.

What exactly comes in the Blaster Guts kit?

The kit includes all the small parts needed for the fire control group, safety controls, bolt catch, and magazine catch assemblies: pivot and takedown pins with springs, mil-spec cast bolt catch with buffer and spring, safety selector with detent and spring, mag catch with steel button and spring, buffer retainer pin and spring, and trigger and pistol grip hardware.

Is this kit suitable for a first-time AR builder?

The Blaster Guts is a kit of individual components, not an assembled unit. It's intended for builders who understand mil-spec AR assembly and are comfortable working with small springs, pins, and detents. If you're new to AR builds, consider pairing this kit with a quality assembly guide or getting support from an experienced builder.

What's the difference between cast and QPQ steel in this kit?

The kit uses mil-spec cast steel for parts like the bolt catch and safety selector—a standard, reliable choice. Critical wear surfaces and detents are finished in QPQ (a case-hardening process) for enhanced durability and corrosion resistance. This combination balances cost with longevity in field use.
