Description
The Sons of Liberty Gun Works (SOLGW) Liberty Fighting Trigger (LFT) is a premier “enhanced mil-spec” trigger. While many standard AR-15 triggers are inconsistent, the LFT is famous for its strict quality control, ensuring a predictable, crisp break every time.
Core Specifications
| Feature | Details |
| Type | Single-Stage Combat Trigger |
| Pull Weight | 5.5 lbs – 6 lbs (Consistently checked by SOLGW) |
| Coating | Nickel PTFE (Teflon) – Provides a permanent “slick” feel and high corrosion resistance. |
| Pins | Includes high-quality QPQ Stainless Steel Trigger/Hammer pins (.154″ diameter). |
| Reset | Shorter and more tactile than a standard mil-spec trigger. |
Why It’s Called a “Fighting” Trigger
Unlike match triggers that use light springs to achieve a low pull weight (which can lead to light primer strikes), the LFT uses full-power mil-spec springs.
- Reliability: It will ignite even the hardest military surplus or steel-cased primers.
- Smoothness: The Nickel PTFE coating removes the “grit” or “sandiness” common in standard phosphate-finished triggers.
- Installation: It ships with a stainless steel slave pin, which holds the trigger and spring together for easy insertion into the lower receiver.
Expert Insight: “Nickel Boron” vs “Nickel PTFE”
You mentioned Nickel Boron (NiB), but SOLGW specifically uses Nickel PTFE (Teflon). While both are silver/nickel-based, Nickel PTFE is arguably superior for triggers because it has a lower coefficient of friction and doesn’t develop the “crusty” carbon buildup that NiB sometimes can after high-volume fire.
