The main difference is the adjustment screw positioning. In BLEED OFF® mode the adjustment screw is not exposed to high pressure gases, heat and carbon fouling giving your gas block a long service life. Running in restrictive mode may eventually erode and/or seize the gas adjustment screw from operating effectively. 

Using the right amount of gas pressure in BLEED OFF® mode has many benefits: 

> Proper cycling of the bolt carrier group. 

> Less felt recoil allowing for faster follow up shots. 

> Less heat and carbon fouling, keeping your system cooler and cleaner. 

> Minimize wear on the internal components. 

> Adjustment screw is not exposed to high heat, pressure and fouling. 

Although you can use your gas block in restrictive mode, we always recommend using the bleed off mode to experience the benefits listed above. If you plan on shooting in restrictive mode, we highly recommend backing the gas adjustment screw out counterclockwise until it stops and apply a dab of anti-seize to the gas adjustment screw before going into restrictive mode.

Our piston system is NOT rated for 300BLK. Low pressure from this caliber creates cycling issues which reduces reliability. We will not warranty the piston system if used with this caliber. We recommend using our Direct Impingement Clamp On Gas Block (SABO-DI-750CM) for 300BLK.

With a set of calipers, measure the diameter of your barrel at the gas port location. Most barrel manufacturers will provide this information on their product pages. We offer the following sizes: .625″ / .750″ / .875″ /.936″ for Direct Impingement Gas Blocks and .625″ / .750″ for Piston System Gas Blocks.  

YES! Our carriers and gas blocks work with any Superlative Arms op rod (pistol/carbine/mid/rifle). Just be sure the barrel diameter is the same as the gas block. You will also want to verify the gas port location before installation. Make sure it meets our specifications before installation or use. Gas port location is critical for the op rod length. If it is not the same distance as stated on our schematic (found on each product page), you will bend the op rod. However, in some cases, we can cut you a custom op rod to fit your setup. Please call 727-849-6880 for details.  

It is a patented locking detent mechanism located exterior of the gas block, not allowing carbon fouling to seize it from operating. There is a flat on the adjustment screw that tells the end-user that it is in the last position of adjustment or at maximum Bleed Off. This also prevents the screw from backing out completely.  

This is normal. It will not affect accuracy or reliability. You can also remove the gas rings since they are no longer needed.
