SLR Rifleworks Sentry 7 AR-15 Adjustable Gas Block - Set Screw - .750"

The SLR Rifleworks Sentry 7 AR-15 Adjustable Gas Block is built for rifles running into reliability issues from being over-gassed or under-gassed. With 15 adjustment positions on a .750" gas seat, it lets you tune your AR-15 for an SBR, a suppressor, light varmint loads, or heavy surplus ammunition, whatever the setup demands.

Features:

• .750" gas block diameter, set screw design
• 15 adjustment positions
• .125" port opening
• Precision-machined metering screw for repeatable settings
• Includes tool to adjust the metering screw
• Melonite-finished 4140 steel construction
• Uses standard gas tubes
• Roll pin and mounting screws included
• Needs a handguard with at least 1.4" internal diameter to hide underneath
• .400" set screw spacing
• Weight: 1.3 oz

Positive tactile clicks between each of the 15 settings make it easy to return to a known-good position after cleaning or changing ammunition, and the precision-machined metering screw and bore keep those settings consistent shot to shot. The gas block, metering screw, and detent plunger are all Melonite finished for corrosion resistance, and everything needed for installation, down to the adjustment tool, ships in the box, so there's nothing extra to source before getting the rifle running reliably.
