The Trident MK3 SPR-M by Krytac is an updated iteration of a highly successful and recognizable AR-15 replica — an elegant yet highly versatile configuration built in a compact but accurate long-rifle format. Compared to previous iterations, the MK3 M model replaces outdated Keymod slots with the modern M-LOK system and introduces numerous upgrades to the gearbox and internal components. Designed as a “special purpose rifle,” it is the longest rifle in the Trident family, emphasizing accuracy, stability, and extended-range performance.

The MK3 SPR-M is manufactured using modern casting and machining technologies. The upper and lower receivers, outer barrel, and collapsible stock are crafted from metal alloys in a precise production process. The lightweight handguard is CNC-machined from aircraft-grade 6061-T6 aluminium. All external components are coated with a matte, scratch-resistant, anti-reflective finish, ensuring protection against field wear and harsh treatment.
Smaller components such as takedown pins and QD sling points are machined from steel for excellent durability.
Only the pistol grip, stock body, and magazine are made from high-quality, lightweight polymers.

The MK3 SPR-M uses a standard AR-15 upper and lower receiver layout, providing excellent ergonomics and broad aftermarket compatibility. The replica accepts standard AR-15-pattern magazines.
A 406 mm aluminium outer barrel houses a 416 mm high-precision inner barrel with a 6.03 mm bore. The barrel ends with a birdcage-style flash hider mounted on a 14 mm CCW thread.
The collapsible stock is comfortable, easily adjustable, and designed to accommodate different battery types. Its angled cheek rest improves sight alignment and aiming speed.
The Trident MK3 SPR-M is equipped with an ambidextrous selector switch, ensuring intuitive use for both right- and left-handed players — a crucial feature in dynamic scenario-based airsoft environments.

At the front, the rifle features a high-quality free-float aluminium handguard with multiple M-LOK attachment slots across seven mounting positions. Combined with the long top RIS rail formed by the upper receiver and handguard, players can attach optics, grips, lights, lasers, and other mission-specific accessories.

At the heart of the replica lies a reinforced, Gate Titan-ready Nautilus V2 gearbox equipped with 8 mm high-performance bearings, a ported full-metal piston, a high-torque motor, and a quick spring change system. These strengthened components significantly improve reliability and durability. The rotary hop-up system stabilizes BBs more efficiently, granting better range and consistent accuracy.
Additionally, the electronics receive major upgrades: an enhanced FET system offering active braking, low-battery detection, and a micro-switch e-trigger. These improvements deliver superb trigger response, lower power consumption, and excellent protection against electrical overload.

Thanks to high-quality materials, precise engineering, and well-thought-out construction, the Trident MK3 SPR-M excels as a designated-marksman-style replica — long-ranged, stable, accurate, and still compact enough to maneuver effectively during skirmishes and milsim operations.
