VM4A1 // BUILT ON KWA. FINISHED WITH RAS-II.

The Custom KWA VM4A1 2.5 Carbine RAS-II Airsoft AEG Rifle starts with KWA’s performance-oriented VM4A1 V2.5 platform and gives the classic M4 carbine a distinctive custom front end built around the:

G&P RAS II RAIL SYSTEM.

Underneath that custom exterior remains the technology that defines the VM4 family: KWA’s Variable Performance System, custom V2.5 gearbox, upgraded high-speed gear set, improved high-torque motor, integrated Switch Life Extender, full-metal receiver construction, PTS Enhanced Polymer Grip, and compatible 30/120-round magazine cut-off system.

It’s a custom M4 that combines recognizable carbine styling with one of KWA’s most feature-rich AEG architectures.

RAS-II

THE FEATURE THAT CHANGES THE BUILD.

The defining component of this custom configuration is its:

G&P RAS II RAIL.

The RAS II gives the VM4A1 a dramatically different front-end appearance from the standard configuration while providing a solid rail interface for appropriately compatible airsoft accessories.

Its traditional Picatinny-style architecture also gives the rifle the unmistakable appearance associated with earlier rail-equipped M4 carbine designs.

For customers who prefer the substantial look of a classic RAS system over a modern slimline handguard, this configuration has a personality all its own.

VPS

VARIABLE PERFORMANCE SYSTEM.

Inside the rifle is one of KWA’s signature VM4 technologies:

VARIABLE PERFORMANCE SYSTEM // VPS.

The VPS allows the rifle’s output configuration to be adjusted through the stock area using the supplied KWA adjustment tool.

KWA lists an approximate adjustment range of:

390 → 440 FPS.

This provides a broader level of factory-designed output adjustment than a conventional fixed-output AEG.

Actual chronograph results can vary with BB weight, hop-up configuration, air seal, spring condition, internal condition and testing methodology, so the published range should be treated as a manufacturer specification rather than a guaranteed velocity.

V2.5

THE POWERTRAIN UNDERNEATH.

The VM4A1 is built around KWA’s:

CUSTOM V2.5 GEARBOX.

Inside, KWA combines an:

UPGRADED HIGH-SPEED GEAR SET

with an:

IMPROVED HIGH-TORQUE MOTOR.

The supplied platform information also identifies reinforced metal gearbox construction, precision metal gearing and KWA’s distinctive 9mm bearing/bushing arrangement.

Rather than relying on the exterior to carry the build, the VM4A1 has a purpose-built electric drivetrain underneath it.

SWITCH LIFE EXTENDER

BUILT INTO THE ELECTRICAL SYSTEM.

KWA equips the V2.5 platform with an integrated:

SWITCH LIFE EXTENDER // SLE.

Its purpose is to help reduce electrical wear on the mechanical trigger contacts.

Repeated electrical operation can gradually wear conventional AEG contacts. The SLE is designed to minimize that stress and help extend the service life of the switching components.

It’s hidden inside the rifle, but it’s an important part of the VM4A1’s electrical architecture.

FULL METAL

A SOLID FOUNDATION FOR THE CUSTOM BUILD.

The custom RAS-II configuration is built around a substantial metal VM4A1 body.

Construction includes a:

ONE-PIECE FULL-METAL UPPER RECEIVER

along with a:

METAL LOWER RECEIVER

METAL BARREL ASSEMBLY

and:

METAL BUFFER TUBE.

That gives the rifle the solid foundation needed to complement the G&P RAS II front end while maintaining the classic proportions of an M4-style carbine.

ROTARY HOP-UP

REFINED M4 ADJUSTMENT.

The supplied VM4A1 platform information also identifies a:

ROTARY-STYLE HOP-UP.

The rotary architecture provides dial-style adjustment for configuring hop pressure according to the BB weight and conditions being used.

As with any AEG, consistency depends on more than the hop unit alone.

Quality BBs, barrel cleanliness, hop-up condition, air seal and proper adjustment all contribute to overall performance.

PTS

ENHANCED POLYMER GRIP.

The lower configuration is finished with a:

PTS ENHANCED POLYMER GRIP.

The PTS grip replaces the basic feel of a conventional M4 motor grip with a more refined component while retaining durable polymer construction.

Together with the G&P RAS II, it gives the custom VM4A1 recognizable aftermarket character at both ends of the rifle.

30 / 120

MAGAZINE CUT-OFF SYSTEM.

The VM4A1 is compatible with KWA’s:

30 / 120-ROUND MAGAZINE SYSTEM.

Compatible magazines can provide selectable 30/120-round capacity along with the VM4 platform’s magazine cut-off functionality.

This feature depends on the correct magazine architecture.

A conventional M4 AEG magazine may physically fit depending on the model, but it should not automatically be expected to provide the VM4’s cut-off functionality.

REAR-WIRED

LIPO-READY PLATFORM.

The VM4A1 is configured as a rear-wired AEG and is described by KWA as:

LIPO READY.

Battery voltage, connector type, physical dimensions and electrical specifications should always be matched to KWA’s current recommendations for the exact rifle.

LiPo-ready does not mean that every LiPo battery is appropriate for the platform.

CHRONOGRAPH BEFORE FIELD USE.

The VPS gives the VM4A1 useful factory-designed adjustability, but the upper end of the manufacturer-listed range may exceed the limits of some airsoft fields.

Always verify actual muzzle velocity and energy with a chronograph using the BB weight required by the field.

Field limits vary, and a particular VPS position should never be assumed to equal a guaranteed FPS or joule output.

CUSTOM KWA

VM4A1 2.5 // G&P RAS-II.

The Custom KWA VM4A1 2.5 Carbine RAS-II Airsoft AEG Rifle combines KWA’s sophisticated VM4 architecture with the unmistakable appearance of a G&P RAS II-equipped M4 carbine.

Its combination of G&P RAS II rail system, KWA Variable Performance System, approximately 390–440 FPS manufacturer-listed adjustment range, V2.5 metal gearbox, upgraded high-speed gears, improved high-torque motor, integrated Switch Life Extender, rotary hop-up, full-metal receiver construction, PTS Enhanced Polymer Grip and compatible 30/120-round magazine cut-off system creates a custom M4 with far more beneath the surface than its classic carbine profile suggests.
