SOLGW Blaster Starter Kit - Complete Tactical AR-15 Build Package

The SOLGW Blaster Starter Kit from Sons of Liberty Gun Works is a complete small-parts package designed to get your AR-15 build off the ground. Whether you're assembling your first rifle, working on a competition gun, or building a reliable defensive carbine, this kit bundles the mil-spec components you'll need for the lower receiver. It's a smart choice if you want to buy the fiddly bits together rather than hunting down each spring, pin, and detent individually.

This is a no-frills, function-first kit. SOLGW manufactures these parts to mil-spec standards, so they'll work with most standard AR-15 lower receivers. The kit focuses on the parts that matter: takedown and pivot pins, safety selector, bolt catch, magazine catch, and all the springs and detents that make your controls work smoothly. Nothing fancy, nothing unnecessary—just solid parts that belong in any build.

If you're sourcing parts piecemeal, you know the frustration of watching your cart total climb as you add one spring here, one pin there. This kit consolidates those essentials into one purchase, saving you time and shipping headaches. Many builders appreciate having a complete set of small parts on hand, especially if you're working with a new lower or replacing worn components.

Frequently Asked Questions

Will these parts work with my AR-15 lower receiver?

Yes—SOLGW manufactures these components to mil-spec standards, so they're compatible with most standard AR-15 lower receivers. If your lower is mil-spec, you're good to go.

Is this a complete lower build kit?

This is a small-parts kit. It includes the pins, springs, detents, bolt catch, safety selector, and mag catch—the internal components you need. You'll still need to source your lower receiver, stock, grip, and trigger group separately to complete a full build.

What's the difference between the regular takedown pins and the QPQ steel ones?

The kit includes both standard takedown pins and QPQ steel takedown pins. QPQ is a case-hardening process that increases durability and corrosion resistance, making those pins more robust for heavy use.

Can I use this kit if I'm building my first rifle?

Absolutely. This kit is a solid foundation for a first build. You'll have all the small parts that often trip up new builders, and the included components are straightforward mil-spec fare that play well with standard lower receivers.
