Superlative Arms.750″ Adjustable Gas Block, Set Screw Mount Stainless Matte Finish

Low Profile, Adjustable, Direct Impingement, Forward Venting “Bleed Off.”

SABO-DI-750SS: Superlative Arms Direct Impingement (DI) adjustable gas blocks are ideal for many tactical setups and shooting styles.  The Sup Arms patented DI “Bleed Off” design adjusts the gas flow by bleeding the gas from the block instead of restricting the flow like a conventional adjustable block. The pressure in the block reduces to only the amount required to drive the bolt carrier group. The remaining pressure bleeds from the front of the block, reducing felt recoil and allowing the system to run cleaner and cooler. This performance-driven design reduces blowback and is beneficial on SBRs or when using a suppressor. If you want the best Set Screw-mounted gas block on the market, look no further!

The gas adjustment screw does not restrict the gas flow, so there is no erosion or seizing of the screw / no loss of detent due to carbon build-up. Although removable, a safety mechanism prevents the screw from coming out. Sup. Arms adjustable gas blocks feature 30 positive-lock gas settings, accessible without hand-guard removal.
