Building or tuning an AR-15 upper? The Kak Industry Low Pro Gas Block in .750 diameter is a no-nonsense steel component built to manage gas flow and bolt cycling on your rifle. This low-profile design fits cleanly under most handguards and barrel configurations, making it the practical choice for shooters who want a compact gas block without sacrificing durability or function. Whether you're assembling a new upper or refreshing an existing one, this block delivers the straightforward performance that makes AR building straightforward.
Kak machines this block in-house from 4140 steel and applies a manganese phosphate finish—a time-proven treatment that resists corrosion and wear. The .750 bore accommodates standard AR gas tubes, and the included hardware (two knurled set screws and one gas tube roll pin) means you get everything needed to install and secure it without hunting for extras. The knurled set screws are designed to grip firmly without rounding, and the 425-degree set screw spacing keeps the block locked in place under firing.
If you're assembling a rifle or replacing a worn gas block, this is the kind of straightforward, durable part that fades into the background once installed—exactly what you want from a gas block. No frills, no marketing talk; just solid steel and proven materials that cycle rounds reliably.
| Brand | Kak Industry |
| Product | Ar15-Up-001 Low Pro Gas Block |
| Bore Diameter | .750 |
| Material | 4140 Steel |
| Finish | Manganese Phosphate (Blasted) |
| Set Screw Spacing | 425 degrees |
| Included Hardware | 2 Knurled Set Screws, 1 Gas Tube Roll Pin |
The .750 bore is compatible with standard AR-15 gas tubes. Verify your barrel's gas port diameter and gas tube setup before ordering to ensure proper fit.
Yes. The block includes two knurled set screws for clamping and one gas tube roll pin. You'll need a wrench to tighten the set screws, but all necessary fasteners are in the box.
The low-profile design is engineered to sit low on the barrel. Most standard and slim-profile handguards will clear it, but tight-fitting or very slim handguards may need verification with your specific setup. Measure your gas block height and handguard clearance if you're unsure.
Manganese phosphate is a durable, corrosion-resistant treatment that's been the standard on rifle components for decades. It protects the steel under normal shooting conditions and field use without adding significant bulk or cost.
