One Horse Low Profile Steel Gas Block Features The One Horse Low Profile Steel Gas Block is machined from high strength carbon steel and finished with a durable Black Nitride coating for long term corrosion resistance. Built for .750 inch diameter barrels it is sized for one of the most common gas block diameters used on AR-15 rifles. Its sleek low profile design sits cleanly under free float handguards helping maintain a streamlined look while protecting the gas system from impact. Reliable gas flow through this block supports consistent cycling of the AR-15 action across a range of ammunition loads. Included set screws make installation quick and secure letting builders mount the block without sourcing separate hardware. Because the block is made in the USA from steel rather than lighter alloys it offers exceptional durability under the heat and pressure cycling an AR-15 gas system experiences. The low profile shape is specifically intended to optimize fit under free float handguards for a clean custom rifle build. Builders upgrading or repairing an AR-15 gas system will find this gas block a reliable American made option that balances durability with a clean aesthetic.
