Key features

• HAL™ ETU system — trigger detection with magnetic sensors and Hall effect, active brake, binary trigger, adjustable trigger sensitivity (5 levels from 20% to 100%), adjustable pre-cocking (6 levels), programmable AUTO fire modes (full auto, semi, 3-round burst, 5-round burst) and programmable SEMI fire modes (semi, binary, AUG, sniper). Easy programming via the trigger and a built-in low battery alarm keep you in control on the move.
• Magnus TDC rotary Hop-Up — Magnus Top-Down Center chamber delivers consistent BB backspin for tighter groupings and improved range, even when the wind shifts on the field.
• Enter & Convert quick-change spring system — field-friendly tuning that minimizes downtime; compatible with higher-tension springs for tournaments and field play (kit includes M90 spring for quick baseline tuning).
• Industrial-grade build — sheet steel body with steel components (barrel, breech cover, outer barrel, trigger guard, magazine catch, selector wing, dummy gas tube, QD mounts, extractor, pins and rivets) and zinc/aluminium alloy parts (dovetail mount, discharge device, sights, dummy slide). Pistol grip, handguard, and adjustable tactical buttstock are polymer for balanced weight and handling.
• Internal engine — Gearbox ORION™ V3, designed for tuning and ready to accept higher-power springs; reinforced internals include a polymer piston with full steel jaw, double-sealed aluminium cylinder head, aluminium sealed nozzle, polymer sealed piston head, and polymer bearing spring guide.
• Practical field features — abundant space for a stick-type LiPo battery under the lock chamber cover, making battery management straightforward; side dovetail mounting rail for optics and accessories; one-piece steel external barrel for durability.
• Package contents — 2 x mid-cap S-MAG magazines, cleaning rod, Allen key, small Tamiya-Deans adapter, BBs speedloader, and an M90 additional spring. Note: battery and charger are not included.
• First-time setup tip: When powering on for the first time, immediately after connecting the battery, hold the trigger in SAFE mode for about 5 seconds to activate the HAL™ module.
