Description
MPN: SUA-SABO-DI-625 / SUA-SABO-DI-750
FEATURES:
- Can be used as a standard gas restricting or a "Bleed Off” adjustable gas block
- Patented "Bleed Off" design allows gas flow to be adjusted by bleeding the excessive gas out from the gas block instead of restricting the gas flow
- Bleed Off port reduces blowback when using a suppressor
- Reduces felt recoil
- Reduction of wear on the bolt carrier group components
- Patented adjustment detent is located outside of the block and therefore no contamination
- Cooler and cleaner gas system
- Safety detent prevent unintentionally backing the screw all the way out
- Made in U.S.A.

DETAILS:
When you build an AR platform weapon, change a barrel, or simply want to upgrade a gas block in your current gas impingement system, you have to choose whether you want to install a standard gas block or an adjustable one. The Superlative Arms Adjustable Gas Block brings a third option to the table, and this one includes features that just might be the answer everyone is looking for. The SA Adjustable Gas Block is a bleed-off gas block that doesn’t control gas flow with the same screw you adjust with, so it really is adjustable for its service life.
WHY AN ADJUSTABLE GAS BLOCK?
The Superlative Arms Adjustable Gas Block is a fully adjustable gas block that also includes a bleed-off feature. The bleed-off feature allows the shooter to set the gas block to allow a portion of the gases produced on firing to exit from the SA gas block itself, reducing overpressure in the impingement system without forcing it all through the muzzle. Using this bleed-off gas block lets your AR run cooler and cleaner than ordinary gas management with less blowback, especially when you’re running a suppressed system.
THE SUPERLATIVE ARMS ADJUSTABLE GAS BLOCK MOVES THE ELEPHANT OUT OF THE WAY
When you talk about adjustable gas blocks, most of the time you’re talking about a gas block you can easily set where you want it when it’s new, but if you want to change it after a few hundred rounds, you might be using some of the more colorful words in your vocabulary as you tear off your handguard to get to work on a stuck set screw. That's the elephant in the room when you talk about adjustable gas blocks. Sometimes that adjustability "option" becomes more optional than adjustable, but not with the Superlative Arms Adjustable Gas Block.
The problem with most adjustable gas blocks is that they control the flow of gas with the same screw you turn to make the adjustments. After a few hundred rounds that screw gets fouled, maybe even corrodes and the easy adjustability you bought it for is a thing of the past. That’s not a problem with the SA gas block because its unique design uses an adjustment screw that isn’t actually responsible for the restriction of gas flow, so it remains free and clean, even after repeated firing. That's one way to give yourself an edge.
CHOOSE YOUR SIZE AND ATTACHMENT TYPE
Superlative Arms Adjustable Gas Blocks are available in a variety of diameters, and finishes and can be purchased as clamp-on components as well as a solid set screw-secured version. don't settle for what another manufacturer is willing to give you.
ADJUSTING THE GAS PRESSURE:
The Superlative Arms® patented “Bleed Off®” gas block comes to you with the adjustment screw in the closed position (zero pressure). From here you will adjust the piston gas block utilizing the 3/32” Allen wrench provided. Start by backing out the gas adjustment screw counterclockwise four and a half revolutions or 18 clicks (there are 4 clicks/revolution). This is equal to a non-adjustable gas block at full pressure. A barrel manufacturer will port their barrels for a non-adjustable gas block. From 18 clicks you have 30 more clicks of adjustment you can make before the patented exterior detent mechanism of the Superlative Arms gas block prevents the gas adjustment screw from coming all the way out. This is a reference point so the end user knows this is the last position of adjustment. Do not over torque as this will damage the plunger.
CLICKS OF ADJUSTMENT:
0: CLOSED
1-17: RESTRICTIVE MODE
18: FULLY OPEN, FULL PRESSURE (ACTING LIKE A NON-ADJUSTABLE GAS BLOCK)
20-48: BLEED OFF® MODE (RECOMMENDED)
Next, load 5 rounds into the rifle's magazine using the lowest-pressure ammo you plan to use. Keeping your rifle pointed in a safe direction (down range), insert the magazine and charge the rifle. In a safe manner, fire 5 consecutive rounds at your intended target.
