Specna Arms SA-P28 PRIME™ M4 AEG – Compact 12.5” Rifle Black

The Specna Arms SA-P28 PRIME™ is a professional-grade M4/AR-15 platform AEG engineered for serious airsoft operators. This compact 12.5” rifle combines real-steel ergonomics with Specna Arms’ legendary build quality, making it an ideal choice for close-quarters skirmish, confined milsim environments, and urban field play.

Key Features

• Compact 12.5” outer barrel with M-LOK rail system – easy weapon handling in tight spaces
• Brushless motor – quieter, more efficient performance with extended motor lifespan
• Rotary hop-up system – precision backspin adjustment for consistent accuracy
• V2 gearbox – proven reliability, straightforward upgrade path
• Multi-position M4 Crane stock – adjustable length of pull for different operator ergonomics
• CNC-machined aluminium handguard and receiver – professional durability and tight tolerances
• 20mm RIS/RAS + M-LOK rail integration – extensive tactical accessory mounting
• Programmable firing modes – safe, semi, full auto, plus user-configured burst settings

Real-World Use Cases

Ideal for skirmishers who favour CQB gameplay in woodland bunker sites or indoor arenas. Milsim players appreciate the compact footprint and genuine Daniel Defense® inspired ergonomics for realism. Shorter barrel length reduces weight, improves manoeuvrability, and suits operators with smaller frames or those running lightweight loadouts. The brushless motor and rotary hop ensure reliable performance in extended play sessions.
