The Super Performance Series of ultra-low profile gas blocks by Black Dirt Rifleworks is the apex of modern gas block design.  Designed for 100% leak-free performance under the demands of high stress and high heat, the Super Performance Series ultra-low profile gas block lives up to its name in a big way. With its ultra-low and ultra-slim profile, the Super Performance Series Gas Blocks provide a perfect contact free fit with any rail system on the market today and its precise design makes it the ideal companion for barrels with a standard .936 diameter gas journal. Precision machined in Trenton Texas from extreme heat and corrosion resistant 602A super alloy steel, all Super Performance Series gas blocks are microscopically inspected for fractures, high pressure tested and finished by H&M Metal Processing in Akron, Ohio using their patented BlackNitride+™ QPQ Process.

The Difference is in The Alloy!

The engineering team at Black Dirt Rifleworks set out to solve two critical problems that plague almost every other gas block on the market today. Poor fitment resulting in performance draining gas leakage and improper material selection resulting reliability robbing uncontrolled expansion and contraction under high stress / high temperature use. After months of torture testing, the 'out-of-the-box' solution they chose was the super alloy 602A. 602A super alloy steel is an austenitic heat resistant alloy that displays superior strength in the face of temperatures of up to 1200 degrees C, (2200 degrees F).  In fact it is the single strongest and most oxidation resistant wrought alloy currently available for service above 1040 degrees C, (1900 degrees F). While cost prohibitions and a high level of machining difficulty has kept 602A from being used in firearm components up to this point, the outstanding strength displayed by this alloy has seen its popularity flourish in high stress / high heat applications including vacuum furnace fixturing, CVD retorts; rotary calciners, gas fired radiant tubes and many others.

Ready to perform!

Perfect for high stress lightweight builds, Black Dirt Rifleworks Super Performance Series Gas Blocks attach firmly to your barrel using 2 high-temp allen screws on the bottom of the block. 

Installation Note:

These gas blocks are designed to get very hot! Black Dirt Rifleworks highly recommends the use of high-temp Loc-Tite or similar heat resistant thread-locking compounds.
