Nuprol Delta Vanguard Sentinel AEG Rifle

The Sentinel is the full-length field rifle in the Vanguard range. A long, skeletonised KeyMod handguard, extended outer barrel with flash hider, and flip-up iron sights front and rear — it's the build you want for outdoor woodland play where reach and sight radius matter more than tight-space agility.

KeyMod attachment is the older sibling of M-LOK. Slotted teardrop-shaped openings down both sides and the underside of the handguard accept KeyMod-compatible rail sections, hand-stops, and accessories — though the standard has been losing ground to M-LOK across the wider industry, plenty of accessories are still produced for it and the second-hand market is well-stocked.

Like every Vanguard, the Sentinel runs the reinforced V2 gearbox with Vortex programmable ETU at its heart. 18:1 steel gears, 8mm ball bearings, M90 quick-change spring, rotary hop with 50° rubber, Deans wiring, and the same configurable fire selector with semi-only, 2/3/4/5-round burst, binary trigger, and full-auto positions. The longer barrel gives slightly improved BB stability with heavier weights — relevant if you plan to push past 0.28g.
