Construction & Reliability

The Vanguard Spearhead is constructed using durable nylon fibre polymer throughout the upper receiver, lower receiver and handguard. This lightweight construction helps reduce fatigue during extended skirmishes while maintaining the durability required for demanding field use.

Internally, the rifle features a reinforced Version 2 gearbox supported by 18:1 steel gears and 8mm ball bearings. Combined with the Deans wired electrical system, the platform delivers efficient power transfer, reliable cycling and long-term durability.

Performance & Field Use

The Spearhead is built around the Vortex programmable ETU system, allowing players to customise firing behaviour to suit different game types and site requirements. Available firing modes include:

• Semi-Auto Only

• 2-Round Burst

• 3-Round Burst

• 4-Round Burst

• 5-Round Burst

• Binary Trigger Mode

• Full Auto

This flexibility allows the rifle to adapt from CQB-focused gameplay to more tactical outdoor scenarios.

Accuracy is supported by a rotary hop-up chamber, 50° hop rubber and a 6.03mm precision inner barrel. Together, these components provide stable BB flight, reliable consistency and dependable shot placement at a variety of engagement distances.

The hybrid quad rail handguard offers extensive mounting space for accessories while incorporating smoothed side sections that improve comfort and support modern C-clamp shooting techniques. This design provides superior weapon control during rapid transitions and aggressive movement without the bulk commonly associated with traditional quad rails.

The M90 quick-change spring system further enhances adaptability by allowing users to adjust power levels without fully disassembling the gearbox.
