Who This Is For
This kit is ideal for AR-15 builders who already have their fire control group and pistol grip selected and simply need a reliable, quality lower parts kit to complete their build. It's also a smart choice for gunsmiths and enthusiasts stocking spare components, or anyone upgrading from a lower-quality OEM parts kit to Sons of Liberty Gun Works' trusted mil-spec standard.

Frequently Asked Questions
Does this kit include a fire control group or pistol grip?
No. The SOLGW Blaster Starter Kit is designed specifically without the fire control group (trigger, hammer, disconnector, and associated pins) or pistol grip. This allows builders to pair the kit with their preferred trigger group — such as a drop-in cassette or upgraded single-stage trigger — and their grip of choice, while still getting all of SOLGW's quality mil-spec hardware for the rest of the lower.
What lower receivers is this kit compatible with?
The Blaster Starter Kit is built to mil-spec dimensions and is compatible with any standard mil-spec AR-15 lower receiver. Whether you're running a forged, billet, or stripped polymer lower, as long as it conforms to standard AR-15 mil-spec tolerances, this kit will fit and function correctly.
Why choose QPQ finish over standard phosphate or anodized components?
QPQ (Quench-Polish-Quench) is a salt-bath nitriding process that delivers superior corrosion resistance and surface hardness compared to standard mil-spec phosphate (parkerized) finishes. On high-wear components like the safety selector detent and takedown pin detents, QPQ helps extend service life and maintain smooth operation even under heavy use or adverse conditions — a key reason SOLGW specifies it on critical steel parts in this kit.
