Sadlak Industries
The Sadlak Industries AR-15 Skeletonized Lo-Pro Gas Block in .625" diameter is a purpose-built component for builders and upgrades on modern carbines and rifles. Built domestically by craftsmen with proven experience, this gas block combines low-profile geometry with a skeletal design that strips away excess weight and material without compromising function. The .625" bore matches mid-length and carbine-length barrels common to most AR platforms, and the low-profile profile slides cleanly under free-float handguards for a streamlined, modern look while preserving maximum gripping surface on your fore-end.
Precision matters in gas block manufacturing—every bore is honed to exacting tolerances, and critical dimensions are 100% inspected to guarantee consistency. This one mounts securely to your barrel using included setscrews; the clamp-style attachment cinches around the barrel as you tighten the side-mounted fasteners for a solid, repeatable hold. Steel construction with manganese phosphate finish delivers durability and corrosion resistance through years of shooting and maintenance cycles.
Whether you're assembling a new rifle from a stripped lower or refreshing an existing upper, the Sadlak skeletonized lo-pro delivers proven performance without the weight penalty of heavier designs. All required hardware is included—no additional purchases needed to get running.

This model is a fixed-position, non-adjustable gas block. The setscrews secure it in place once you've positioned it on the barrel.
