Product description
EGW Gas Block: Machined Aluminum with Picatinny Rail for Accessories
Features
- Picatinny top rail for mounting backup sights or accessories
- Fits .875″ diameter barrels
- Machined aluminum construction
- Won’t interfere with optics or free-float handguards
- Easy installation with hex screws
- Roll pin included
The Evolution Gun Works gas block solves the accessory mounting problem by adding a Picatinny rail that accepts backup front sights, lights, or lasers without adding bulk to your handguard. This gas block works well for heavy profile barrels needing front sight mounting, shooters who want tactical accessories at the muzzle end, and free-float handguard setups where rail space is short or limited. The machined aluminum construction properly directs gas flow while keeping weight down, and hex screw installation makes setup straightforward without specialized tools.
