S&T ST46 Sports Line PDW M4/AR-15 AEG

The ST46 features a combination of both polymer and alloy throughout its build and feels solid as a rock, yet lighter than other PDW replicas. Gone are the days when polymer meant shiny, squeaky and rattley rubbish, the polymer of the ST46 feels great in the hands and will not get greasy over time thanks to its textured finish. The ST46 is sturdy, with no rattles, wobbles or other complaints to be found. It is the perfect tool to use as a backup to a full metal AEG around the end of the day when the arms get tired or for those with less physical strength.

Starting at the tip of the outer barrel we can find an alloy birdcage flash hider attached to the 14mm CCW male threading of the barrel. This means you can add a tracer or suppressor straight away and all you need to do is remove the flash hider grub screw and unscrew it. The barrel is constructed from alloy also, ensuring it is strong enough to survive the trials and tribulations of any skirmish setting.

Moving rearwards, we come to the handguard of the ST46 PDW which is constructed from alloy. The handguard is equipped with a 20mm Picatinny rail along its entire upper surface, allowing for a wide range of 20mm Picatinny rail accessories to be added without having to sacrifice all the space to mount your choice of optical sight. At the 3, 6, and 9 o'clock positions, we are treated to M-LOK attachment slots, allowing you to mount grips or extra Picatinny rails, the options are endless!

The upper Picatinny rail of the handguard runs back and meets the receiver rail seamlessly to allow for longer optical sights to be mounted, including red dot sight and magnifier combinations. The receiver itself follows the familiar M4/AR-15 format and is constructed from high-density polymer to keep the platform light and manoeuvrable. The finish on the receiver is consistent and strong enough to resist scratches more effectively than most metal receivers, making the DA-B18-EGL ideal for those who skirmish recklessly!

The fire selector is positioned just above the pistol grip and offers 3 modes of fire; SAFE, SEMI and AUTO, with a 90-degree throw between each mode. This makes the selector easy to switch with your thumb, but not so easy that it can be changed accidentally. The magazine release is on the right side of the magazine well and is accessible for a right-handed user with the tip of the trigger finger.

The mock bolt catch is located in the centre of the left side of the receiver, and while this is a dummy control which doesn't provide a function it is nonetheless a separate part to maintain the realistic appearance and avoid the tell-tale signs of being a replica. The dummy forward assist is present on the right side of the upper receiver, right where it should be, reprofiled to match modern "billet" style receivers with their dynamic angles. This control does nothing on an AEG, and some real AR shooters argue it does nothing on the real thing, but it is included on the ST46 to keep the rifle faithful to real M4/AR-15 rifles.

The charging handle is located at the top rear of the receiver and doesn't need to be pulled before the first shot. It instead serves to retract the mock bolt carrier and open the dust cover on the right side of the upper receiver, which allows us to access the rotary HOP-up unit inside. The HOP-up allows you to tune the flight path of your BBs and set the ST46 up for different ammo weights, looking for the flattest trajectory possible. The use of the rotary adjuster style is a nice touch and futureproofs the ST46 with the most modern HOP-up design for the M4/AR-15 platform, boasting an improved ability to hold its setting under the vibrations of firing and being adjustable in finer increments than the older "gear" adjuster design.

The pistol grip of the ST46 boasts a refined ergonomic grip angle for greater comfort when shooting with the stock fully collapsed and in more modern shooting stances. The sides of the pistol grip include fine texturing, with a finger ridge on the front for improved grip. The trigger is a classic curved trigger, making it ideal for firing out long intervals of full auto firing. The trigger guard is built into the receiver, improving strength and allowing gloved fingers easier access to the trigger than the standard AR flat trigger guard.

As we reach the rear of the AEG we can find the unusual stock situation. The compact PDW stock of the S&T ST46 PDW allows it to be stowed in much smaller spaces and used in a much more compressed shooting stance. The stock is primarily constructed from alloy with a polymer butt plate and steel stock bars for additional strength. The adjustment lever can be found on the bottom of the stock and allows the user to extend the stock to multiple different positions, depending on your body type and the scenario.

The battery compartment of the ST46 PDW can be found within the buffer tube, which is secured via a threaded cap that twists onto the buffer tube and will keep your battery secure and waterproof. The AEG is equipped with a Deans connector and can house a 7.4V LiPo battery of up to 600 mAh capacity. The Specna Arms 7.4V 600mAh 20/40C Battery for PDW is recommended, however, due to its small size it's best to bring two of these to your skirmishes so you will have enough battery power to play all day!

On the inside, the ST46 has a basic but reliable internal setup, with an alloy version 2 gearbox with steel gears and full compatibility with aftermarket upgrades. The use of a rotary HOP-up unit will provide ample range when combined with its 6.03mm inner barrel, but if you want more, the hop-up and inner barrel are also compatible with Tokyo Marui upgrade parts. The preinstalled MOSFET protects the ST46 from electrical errors and also noticeably improves the trigger response.

For those who are relatively fresh to the battlefield or maybe an experienced Airsofter looking for a lightweight backup platform, the S&T ST46 Sports Line PDW M4/AR-15 AEG is perfect for your needs. Its compact size and polymer receiver is optimal for any close-quarter battle and the preinstalled MOSFET and Deans connector ensure the electrical internals will be safe and sound for years to come!
