Slim Profile Design: The D2 Series boasts a streamlined profile, purpose-built to fit cleanly beneath even the slimmest profile hand guards with top rail, such as our M-LOK Series.

Short Journal Optimized: Shorter dimensions cater to shorter gas block journals such as those on Proof Barrels, ensuring a superior fit.

Enhanced Dirt Tolerance: The exterior detent mechanism on the nut enhances dirt and carbon tolerance while the robust 5/32 drive also allows for heavier torque to overcome and easily eject fouling.

Minute Adjustment Refinement: With 52 clicks between full open and full close, the D2 Series doubles the adjustment clicks of our current detent blocks, making them ideal for SBRs and other high-pressure/short-dwell-time barrels.

Versatile Adjustment Options: The adjustment nut features a 5/32 hex drive and slots, providing flexibility for customization with a range of tools, including screwdrivers and knives.

Lightweight Design: The D2 Series add negligible weight at just 2.5 oz.
