The Zion Arms R15 Mod 1 Long Rail Airsoft Rifle with Delta Stock in bronze is built for players who want extended reach, strong field presence, and dependable performance in a full-length AEG platform. Featuring CNC aluminum upper and lower receivers paired with a polymer grip and stock, this electric automatic airsoft rifle delivers a realistic feel with a durable, competition-ready build. Shooting at 380 to 400 FPS with 0.20g BBs, it is well suited for outdoor fields and mid-to-long range engagements. Internally, the reinforced full metal version 2 gearbox uses ultra-smooth 8mm bearings, 18:1 steel gears, a steel-tooth polycarbonate piston, and a bearing spring guide, all driven by a 19k RPM neodymium high speed motor for consistent cycling and trigger response. Accuracy and range are enhanced by the copper polished 6.03mm tightbore inner barrel working in combination with the Kinetic TDC hop up system for precise, repeatable adjustments.

Includes Lancer Tactical's Kinetic TDC hop up system, which replaces traditional swinging arm designs with true top down vertical pressure for perfectly centered BB contact. This system eliminates side loading, delivering a straighter and more consistent flight path, especially when using heavier BBs. The tactile rotary adjustment dial provides precise micro click control that locks settings in place, even under sustained full auto vibration. Paired with a pre installed flat hop bucking and nub, the Kinetic system increases surface contact on the BB for improved range, accuracy, and long term shot stability, bringing pro level hop up performance as a factory standard component.

The long rail Mod 1 design emphasizes customization and control, starting with a 10 inch M-LOK handguard that offers generous mounting space for lights, lasers, and other mission-essential accessories. Integrated QD sling mounting points on both sides allow flexible sling setups, while the full length 20mm Picatinny top rail supports optics, magnifiers, and PEQ boxes with ease. The Zion Arms fully programmable electronic trigger unit enables burst firing modes and smooth semi-automatic performance, enhanced further by a flat trigger and enlarged trigger guard for rapid follow-up shots. Rear-wired Deans connectivity supports high output 11.1v LiPo batteries, and the quick change spring system allows easy FPS tuning through the rear of the rifle. Finished in a distinctive bronze color, the Zion Arms R15 Mod 1 Long Rail airsoft rifle stands out as a premium AEG that blends aggressive styling, extended rail versatility, and reliable field performance for serious airsoft players.
