AR-15 – Lower Parts Kit – Ambidextrous – Liberty Fighting Trigger with B5 Grip
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Sons of Liberty Gun Works Enhanced Blaster Guts kit is a premium AR-15 lower parts kit built around the Liberty Fighting Trigger, a B5 pistol grip, and a mil-spec ambidextrous safety. This is for builders who want better parts from the jump instead of buying a cheap kit first and then slowly replacing the junk they already paid for.
SOLGW positions this as an enhanced lower build kit, not a bare-bones parts bag. It is meant to give you a cleaner starting point for a serious rifle build with upgraded controls and a better trigger setup right out of the gate.
Fitment
- Fits AR-15 pattern lower receivers
- Designed for standard AR-15 small-frame builds in 5.56 NATO / .223 Rem and similar AR-15 pattern configurations
Does NOT fit
- Does not fit AR-10 / LR-308 / large-frame rifle platforms
- Do not assume compatibility with nonstandard or proprietary lower receiver systems
What it does
This kit gives you the core lower receiver parts needed for an AR-15 build, while upgrading key touch points with the Liberty Fighting Trigger, B5 grip, and ambidextrous safety. It is built to improve control, feel, and overall lower completion quality compared to bargain-bin kits.
Why it’s worth it
If you are already building with quality in mind, this kit saves time and cuts down on part-swapping later. The ambi safety and better trigger make real use-of-rifle improvements, and the B5 grip keeps the package from feeling like a random mixed-parts compromise.

Install notes
This is lower receiver build hardware, so install should be done with proper tools and actual attention to detail. Verify spring orientation, selector function, trigger reset, and safe operation before live fire.
Verify before you buy
Verify you are building on a standard AR-15 lower and that you specifically want the ambidextrous safety version with the B5 grip and Liberty Fighting Trigger. SOLGW has other Blaster Guts variants, and buying the wrong one because the names look similar is a dumb way to waste money.
