Sons of Liberty Gun Works (SOLGW) Liberty Gas Block – .750 Stainless – SOLGW-LGB-750SS
The Sons of Liberty Gun Works Liberty Gas Block (SOLGW-LGB-750SS) is a professional-grade 2026-spec component designed for mission-critical reliability in AR-15 and AR-10 platforms. While many standard gas blocks are made from carbon steel, the "SS" model is precision-machined from heat-treated stainless steel and finished with a durable Black Nitride coating. This combination provides the best of both worlds: the extreme corrosion resistance of stainless steel and the surface hardness of nitride, ensuring the gas port remains dimensionally stable even under the intense heat and erosive pressure of suppressed fire. Designed for barrels with a .750" gas journal, this low-profile block is slim enough to fit under nearly any modern M-LOK or KeyMod handguard.
Engineering-wise, the SOLGW Liberty Gas Block (657628674351) is built to "seal" better than commercial alternatives. It features a shortened length designed to sit directly against the gas block shoulder of the barrel, eliminating the traditional "handguard cap gap" for a more secure and aesthetically pleasing fit. The block is secured via two knurled-head set screws that "bite" into the barrel dimples to prevent rotation. For the 2026 builder, the Liberty Gas Block also comes pre-dimpled for pinning, featuring a witness mark that allows an armorer to easily drill and install a coil pin for a permanent, "bomb-proof" installation. Backed by the SOLGW "No BS" Lifetime Warranty, this is a "set-it-and-forget-it" internal part for any duty-grade carbine.
Includes: (1) SOLGW .750 Stainless Steel Nitride Gas Block and (2) Knurled Set Screws. (Gas tube pin sold separately).
Key Features
- Stainless Steel Construction: High-grade stainless steel base material offers superior heat and corrosion resistance for high-firing schedules.
- Black Nitride Finish: Provides an ultra-hard surface layer that resists carbon "welding" and environmental wear.
- Low-Profile Design: Engineered to clear the tightest internal diameters of modern slim-line handguards.
- Shoulder-Agnostic Fit: Designed to sit flush against the gas journal shoulder, maximizing gas seal efficiency and reducing leakage.
- Pinning Ready: Includes a machined pilot hole/dimple to assist armorers in pinning the block to the barrel for ultimate security.
- Knurled Set Screws: Features specialized knurling on the screw tips to ensure a positive lock that won't vibrate loose under fire.
