Troy Industries Ar-15 2'' Low-Profile Gas Block .750''Id Black

Building a modern AR-15 with a slim handguard? The Troy Industries 2" Low-Profile Gas Block is engineered to tuck under free-float rails and keymod/picatinny furniture without interference. This is a direct swap for AR-platform rifles running .750" gas tubes, letting you ditch the chunky A2-profile front sight and clean up your receiver's appearance. The low-profile design also covers the taper-pin holes left behind by traditional A2 gas blocks, so you won't have empty divots visible on your rifle.

Troy machined this block from 4140 steel and applied a manganese-phosphate finish for durability and corrosion resistance in the field. At just 2 inches long, it delivers the gas-tube port function you need without the visual bulk of older designs. This is the part serious AR builders reach for when they're tired of compromising between a quality handguard and a functional gas block.

Installation is straightforward for anyone comfortable swapping AR upper components. You'll need to source a gas-tube roll pin separately to complete the assembly, but that's a standard hardware-store find. Dimension check: the .750" inside diameter confirms compatibility with standard AR-15 gas tubes.

Frequently Asked Questions

Will this fit under my slim handguard?

Yes. The low-profile design is specifically engineered to clear free-float and slim-profile handguards that would normally interfere with standard A2 gas blocks.

What gas tube size do I need?

This block is compatible with .750" inside diameter gas tubes, which is the standard for AR-15 platforms. You'll need to source a gas-tube roll pin separately to complete installation.

Does it cover the old A2 taper-pin holes?

Yes. When you install this block as an upgrade from an A2 front sight, it covers those unused taper-pin holes, giving your receiver a finished appearance.

What's included?

The gas block itself is included. You will need to supply your own gas-tube roll pin to complete the assembly.
