Sons of Liberty Gun Works Enhanced Blaster Guts LPK Liberty Fighting Trigger B5 Grip Mil-Spec Safety - EBG-B5-LFT-MS - UPC 691821688753
Product Description
The Sons of Liberty Gun Works Enhanced Blaster Guts Lower Parts Kit (EBG-B5-LFT-MS) eliminates the traditional weak points found in commercial lower component sets. Engineered strictly to USGI Technical Data Package (TDP) specifications or higher, SOLGW utilizes AISI 8620 investment cast steel for critical controls like the bolt catch and safety selector. Rather than using cheap aluminum magazine buttons or commercial MIM small parts, this kit supplies a heat-treated steel magazine catch button and solid hardened stainless steel detents from KNS Precision Machine, preventing binding, galling, and premature wear under hard use.
This package centers around the single-stage Liberty Fighting Trigger (LFT). Coated in a low-friction Nickel PTFE finish on both the hammer and trigger, the LFT delivers a smooth, clean 6-pound duty pull with zero grit and an authoritative tactile reset. Paired with a traditional single-sided mil-spec safety selector and the ergonomic B5 Systems Type 22 P-Grip, this configuration provides an ideal balance of streamlined control and wrist-sparing comfort for modern carbine operation.
Every single pin, spring, and detent in the Enhanced Blaster Guts kit undergoes strict quality inspection. Designed and assembled in San Antonio, Texas, and supported by SOLGW’s lifetime warranty, this complete lower parts kit provides a rock-solid, duty-spec internal foundation for any hard-use defensive or tactical AR-15 rifle.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Compatible with all standard mil-spec forged and billet AR-15 lower receivers using standard .154" fire control pin holes. Fully compatible with 5.56 NATO, .223 Rem, .300 Blackout, 6.5 ARC, and 9mm PCC lower assemblies.
Staging & Installation Steps:
- Degrease all lower receiver pin channels and clean out machining residue prior to installing small detents.
- Install the single-sided mil-spec safety selector along with its detent and spring, verifying crisp rotational detent engagement.
- Install the Nickel PTFE Liberty Fighting Trigger group; ensure the hammer spring legs rest flat inside the trigger pin grooves to lock the pin in place.
- Conduct a full dry-fire function test: verify safety selector lockup, trigger pull, and mechanical reset while riding the hammer forward.
- Mount the B5 Systems P-Grip, taking care that the safety detent spring compresses straight into the grip channel without kinking.
