A Note on BB Care

BB quality and cleanliness, combined with a good barrel and hop-up rubber, are crucial for accuracy. Especially with precision barrels, protect your BBs from dirt (for example, inside the magazine while crawling), and clean your inner barrel regularly to prevent buildup that affects performance.

Key Features

• Biodegradable formula: Faster decomposition, eco-friendly and field-compliant
• Precision tolerance: 5.95mm ± 0.005mm for reliable accuracy
• High-gloss polish: Smooth, consistent surface finish
• Full production control: Perfectly round BBs for flawless feeding

The SA Dark Matter™ is a brushless electric motor, meaning it operates without the carbon brushes found in traditional DC motors. This brushless technology enables smoother, more efficient operation, delivering higher power output that significantly boosts a gun's overall performance — including a faster rate of fire and reduced trigger response time for greater accuracy and faster shooting speed.

The biggest advantage, though, is extended battery life. With a brushless motor, an 11.1V 1000mAh battery can deliver 5,000+ shots, compared to roughly 1,000 rounds from a standard brushed motor. The only trade-off is a higher upfront cost — but this is easily offset by zero maintenance requirements and a significantly longer service life.

Built for durability, the motor is housed in a high-quality aluminum casing with an aluminum end cap. Specna Arms also offers replacement end caps in both aluminum and nylon, in case the connector ever gets damaged.

All Specna Arms brushless motors are rated for use with springs up to M190, but RPM should be chosen based on your specific spring setup — as a rule, the stronger the spring, the lower the recommended RPM.

Key Features

• Brushless technology: No carbon brushes, for smoother and more efficient operation
• Improved performance: Faster rate of fire, reduced trigger response time, greater accuracy
• 5x longer battery life: 5,000+ shots per charge vs. ~1,000 with brushed motors
• Zero maintenance: No brushes to wear out or replace
• Durable construction: Aluminum casing and end cap
• Replaceable end caps: Available in aluminum or nylon
• Spring rated: Compatible with springs up to M190 (choose RPM based on spring strength)

Internal Components
At the heart of this replica sits the HAL ETU™ electronic trigger unit — a genuine leap forward for Specna Arms, pushing what used to be a mid-range lineup firmly into the same performance bracket as the industry's top names. The "HAL" name comes from the Hall effect principle the unit relies on to read trigger input with exceptional precision.

Even before you factor in the electronics, the base platform is well specced: a 6.03 mm inner barrel for tightened accuracy, paired with an adjustable Hop-up chamber fitted with quality rubber. Spring swaps are handled through the ESA quick spring change (QSC) system, so you can move to a stiffer or softer spring without ever pulling the gearbox from the receiver — the whole job is done through the buffer tube. The gearbox itself is reinforced to handle springs rated up to M120, per Specna Arms' specifications.

What the HAL ETU™ unit brings to the table:

Hall-effect magnetic sensor for trigger detection
Active braking system
Binary trigger function (fires on both pull and release)
5-stage adjustable trigger sensitivity (20%–100%)
6-stage adjustable pre-cocking
Custom SEMI modes: semi, binary, AUG-style, delayed sniper
Custom AUTO modes: full-auto, semi, 3-round burst, 5-round burst
Trigger-based programming — no extra tools needed
Low battery alert
Brushless motor compatible (works well with units like the Specna Arms Dark Matter or Warhead)

Exterior Build
The nylon body is finished to a high standard — matte texture, realistic detailing, and fiberglass reinforcement that keeps it both tough and light in the hand. Metal shows up where it counts: the outer barrel, ejection port, and pins are all steel or machined metal, not plastic substitutes.

Built on the familiar AR15 ergonomic platform, the layout feels intuitive from the first grip — controls fall naturally under your fingers and the balance suits fast handling. A CNC-machined metal RIS handguard gives you rail space for grips, AN/PEQ boxes, flashlights, and other accessories, while the Crane-style adjustable stock accepts Buffer Stick, Nunchuck, or Crane battery types, keeping you flexible for different loadout setups.

A replica that punches well above its price point, blending serious internal tech with a durable, field-ready exterior.

Machined from hardened steel, these 7mm bushings feature a double oil groove that holds lubricant against the gear shafts for smoother rotation and reduced wear inside a Version 2 or Version 3 gearbox. Swapping worn stock bushings for a precision steel set tightens gear alignment, cuts drivetrain slop, and helps your AEG run quieter and more efficiently over time. Sold as a full set to replace all shaft positions in a standard gearbox.

Upgrade your V2 gearbox AEG with the Specna Arms HAL electronic control unit, a Hall-effect trigger system that replaces mechanical contacts with magnetic sensors — no more worn microswitches or failing contact points.

Key features:

• Hall-effect magnetic trigger sensing for high sensitivity and long service life
