Build it once, build it right. The Sons of Liberty Gun Works (SOLGW) Blaster Starter Kit is a premium AR-15 lower parts kit finished in black nitride for long-term durability, smooth function, and corrosion resistance. Whether you’re assembling a new lower or refreshing a hard-use carbine, SOLGW’s Blaster Starter Kit delivers duty-grade springs, pins, and controls with the fit and feel serious shooters expect.
Why Choose the SOLGW Blaster Starter Kit
Nitride Finish (Black): Enhanced wear resistance and lubricity on high-contact components for cleaner operation and longer service life.
Duty-Grade Components: SOLGW spec parts are selected for reliable engagement, crisp detents, and repeatable performance under round-count and weather.
Mil-Spec Fitment: Compatible with AR-15 pattern receivers built to mil-spec dimensions for hassle-free installs.
Consistent Controls: Positive selector clicks, confident mag releases, and a bolt catch that just works—from build day to class day.
Smart Value: Everything you need to complete a lower (see contents note below) in one quality-controlled kit from a brand known for hard-use rifles.
What’s Inside (Typical LPK Contents)
The Blaster Starter Kit is designed to provide the core small parts required to assemble a mil-spec AR-15 lower receiver. Typical contents include:
Controls: Safety selector, magazine catch, mag release button, bolt catch, bolt catch roll pin
Pins & Detents: Takedown and pivot pins, detents and springs, selector detent/spring, bolt catch spring/plunger, buffer retainer and spring
Fire Control Group Hardware: Trigger and hammer pins, disconnector spring (FCG components may be included depending on production lot—see note)
Other Small Parts: Trigger guard and roll pin (model dependent), grip screw and washer (model dependent)
Important note: Exact contents may vary slightly by production lot or distributor configuration (some kits include a mil-spec trigger group and A2 grip, others ship minus FCG and grip so you can add your preferred trigger and furniture). Always confirm the current box contents with the product listing before purchase.
Benefits of a Nitride-Finished LPK
Smoother Surfaces: Nitride imparts a hard, low-friction layer that helps parts resist galling and carbon adhesion.
Corrosion Resistance: Ideal for humid, wet, or salty environments—and for rifles that see heavy training cycles.
Long-Term Consistency: Springs and detents maintain positive engagement, so controls feel the same in month twelve as they did on day one.
Ideal For
First-time AR builders who want a trusted, complete small-parts solution.
Experienced shooters refreshing a high-round-count lower.
Duty, defense, and training carbines where reliability is non-negotiable.
Custom builds pairing a premium trigger and furniture with SOLGW’s proven small-parts quality.
Installation Tips (General Guidance)
Unload and clear any firearm before beginning work.
Use the right punches and a bench block to protect receiver ears and finish.
Tape off high-risk areas (bolt catch ears) to prevent marring during roll-pin installs.
Lightly lubricate detents and springs to improve initial feel and reduce galling.
After assembly, perform a full function check: safety on/off, trigger reset (if FCG installed), mag release, bolt catch, takedown/pivot action.
If pairing with a match trigger, follow the trigger manufacturer’s torque and thread-locker guidance.

Care & Maintenance
