The DELTA Vanguard Sentry is built for players who want the freedom to choose their rifle configuration without sacrificing electronic performance. Available in 7", 10" and 13" front-end options, the Sentry adapts to your role, your environment and your play style.

The 7" configuration prioritises manoeuvrability and rapid movement for tight indoor environments and aggressive CQB play. The 10" option offers balanced versatility for mixed woodland and urban sites. The 13" variant extends the front profile for improved stability, sight radius and controlled mid-range engagement.

At its core, the Sentry features the Vortex programmable ETU system. The selector allows semi-only, 2-round burst, 3-round burst, 4-round burst, 5-round burst, binary trigger mode and full auto options. This gives players the ability to tailor firing behaviour to match site regulations or tactical preference.

Internally, the reinforced Version 2 gearbox provides dependable mechanical strength. Supported by 18:1 steel gears and 8mm ball bearings, and powered through Deans wiring, the Sentry delivers consistent cycling and improved trigger signal response.

Accuracy is enhanced through the rotary hop unit combined with a 50° hop rubber and 6.03 mm precision inner barrel. This system promotes stable BB flight and reliable grouping across engagement distances.

Constructed from nylon fiber polymer across the upper receiver, lower receiver and handguard, the rifle maintains durability while keeping weight manageable. The modern skeletonised adjustable stock helps maintain balance regardless of configuration length.

The DELTA Vanguard Sentry delivers modular adaptability backed by programmable performance, giving players the flexibility to build the rifle that fits their mission.
