Description
The VLTOR Set Screw Gas Block (GB-S) is a low-profile, steel gas block engineered to replace the standard front sight base on AR-15 barrels, allowing use of free-float handguards without obstruction. The set-screw design (versus pinned) enables tool-free installation and removal on standard .625" to .750" barrel gas journal diameters. VLTOR's precision machining ensures a consistent, repeatable gas seal for reliable cycling. Low-profile design clears most free-float handguard systems for a clean, unobstructed sight picture. The GB-S is compatible with standard AR-15 low-profile gas block dimensions.
