If you’re a gas tuner, you’re just not satisfied with a standard gas block. You want adjustability. If you’re looking for a high-end adjustable gas block Wing Tactical has something special for you. The SLR Titanium Sentry 7 Adjustable Gas Block is the gas block for those of you who refuse to compromise. The SLR Sentry 7 uses a patented design to deliver true adjustability for real tunable control over your rifle's gas system.

A High-Quality Titanium Adjustable Gas Block

The SLR Titanium Sentry 7 Adjustable Gas Block is sized for barrels with .750” gas block seats and comes in models designed for set screw mounting or clamp on application. Simply check your chosen barrel for dimples. If it has them go with the set screw model, if not, the clamp-on version is the one for you. Either way, you get a fully machined, grade 5 titanium gas block with Melonite coated 4140 metering screw and detent plunger.

The Metering Screw & Flat Spring

The Sentry 7 Gas Block features a special gas block metering screw and flat spring pairing that will maintain adjustability in your Sentry 7 Gas Block long after it’s put to work. The 4140 Nexturn Swiss Precision Metering Screw is fully adjustable through 15 individual positions. It features a quality Melonite coating with outstanding self-lubricity to shed fouling and resist corrosion. That allows you the ultimate in flexibility and sure operation with the SLR Sentry 7, even after you’ve put the rifle in service. Adjustments are easily made with a single tool, one click at a time. The Proprietary design of the flat spring and its 1400-degree tempering assures that it won’t go slack after exposure to the heat produced when the firearm system is put to use.
