Specna Arms SA-C27 CORE™ Gen.2 Daniel Defense® RIII™ 10.5" M4/AR-15 AEG

If you're looking for a real steel styled all-purpose platform, the Specna Arms SA-C27 CORE™ HAL¹ ETU™ M4/AR-15 AEG is worth your scrutiny. Constructed to Specna's CORE standard, the SA-C27 boasts a CNC aluminium handguard and alloy outer barrel and bird cage muzzle attachment paired with a high-density polymer receiver, buffer tube, stock and pistol grip, giving you a great introduction to more realistic replicas, but still easy to use during a day of skirmishing. As with the original CORE series, the polymer quality is top-notch, more scratch-resistant than comparable metal receivers and ultra-light for high energy throughout the skirmish day.

Inside this SA-C27 variant, known as the "Gen.2", we are treated to the advanced AETHER™ gearbox shell and Magnus TDC HOP-up unit of Specna's PRIME™ series, providing enhanced long-range performance and making gearbox tuning a piece of cake. Also inside is the HAL™ ETU/MOSFET, offering binary trigger, AUG mode and sniper delay instead of semi-auto and semi-auto lock, 3-round burst or 5-round burst instead of full auto, along with several quality-of-life improvements and most importantly for CQB, adjustable pre-cocking. Pre-cocking positions the piston at the rear of its cycle after a shot, meaning when you pull the trigger, the response is practically instantaneous, ideal for semi-auto duels in the close confines of a CQB site.

A considerable improvement over the original SA-C27, the Gen.2 enhancements add a lot of functionality to this compact and player-friendly platform. With no more trigger lock-ups when shooting semi-auto, plenty of fire mode options and the pre-installed 6.03mm tightbore inner barrel and Magnus rotary HOP-up combo, the CORE™ Gen.2 line provides more bang for your buck than ever before!

Starting at the front of this powerhouse of a platform, we find a preinstalled bird cage-style flash hider. This is very much the industry standard when it comes to muzzle devices, being present on most Airsoft M4/AR-15 platforms straight out of the box. The muzzle device can be removed by twisting it clockwise, revealing the 14mm CCW threading underneath. This is the most common threading and will accept a plethora of aftermarket tracer units and suppressors.

Then, we immediately come to the handguard. A truly exquisite design. It is an Airsoft replica of the Daniel Defense® Rail Interface System III, RIS III 10.5". The real steel variant is well respected and loved by the American military for good reason, it's effective, tactical and streamlined. The SA-C27 handguard shares these same attributes. It is constructed from CNC Aluminium, guaranteeing flawless form and precise, in-spec attachment interfaces.

The M-LOK design of this handguard modernises its look; it is much less chunky and cumbersome when compared to a 20mm Picatinny quad-railed handguard, and it's much lighter. It's the perfect design for skirmishers who like a streamlined and agile platform to match their playstyle. M-LOK slots are available at the 3, 6 and 9 o'clock positions as well as recessed offset M-LOK slots (these offset slots may only be compatible with some rail attachments). A 20mm Picatinny rail runs along the top and pairs seamlessly with the receiver rail, allowing for longer optical setups to be used with plenty of spare space.

The front flip-up iron sight is present on the handguard's top rail. This polymer-constructed attachment pairs with the rear iron sight found at the back of the receiver. The front sight has an adjustable elevation, and the rear has adjustable windage; together they make an excellent set of backup sights if the worst comes to worst whilst out on the battlefield.

The handguard features a preinstalled angled foregrip, constructed from a strong alloy and designed for quick target acquisition. It matches the streamlined design of the handguard, but it can be removed to make space for an alternative grip. The angled design helps improve stability and control when aiming, which is essential for more accurate shooting. There is a QD swivel point on the handguard and two on the angled foregrip; however, the points should be thoroughly tested for security and strength before being trusted with the weight of your platform for a full day of skirmishing!

Next up, we reach the receiver, which is of a standard and instantly recognisable M4/AR-15 configuration with controls laid out in a considerate and ergonomic manner, allowing the SA-C27 to be manipulated quickly and instinctively by veterans or learned rapidly by new users.

The fire selector lever can be found just above the pistol grip, on the left side of the AEG, providing 3 modes of fire: SAFE, SEMI, and AUTO, with a 90-degree throw between each. The fire modes are helpfully marked in recessed text on the receiver, and the selector switch locks positively into each mode with the help of texture on its surface to guarantee you can stay in control of your fire modes. The magazine release is on the right side of the magazine well and is accessible for a right-handed user with their trigger finger or by a lefty using their off-hand thumb.

Pulling back the extended charging handle, at the rear of the receiver, will pop open the dust cover and retract the mock bolt carrier, which allows access to the rotary HOP-up adjuster. This is the latest HOP-up unit design for the M4/AR-15 and provides finer increments of adjustment and holds its setting more effectively when compared to the older gear-style HOP-up unit. The charging handle has an extended latch for easier access, allowing even those with thick gloves to access the HOP-up unit, though you may need to remove your glove to adjust the unit!

The bolt catch on the left side of the receiver does not function, but is nonetheless a separate movable part to reduce the common tell-tale signs of a replica. The forward assist is a similar story, being present on the right side of the upper receiver and being another separate moving part which can be pressed in, but does not affect the function of the AEG. A new addition to this HAL-equipped SA-C27 is its flat trigger, enhancing the military aesthetic with a touch of modernity and providing an easily slappable trigger for snappy double taps in semi-auto.

The pistol grip of the SA-C27 is an M16A2/M4A1 style pistol grip, also known as the "A2" finger ridged grip. The A2 has diamond checkering on either side and linear texture on the back strap to provide excellent gripping qualities, whether you wear gloves or not. The finger ridge is designed to help you keep hold of the rifle and prevent the grip from slipping out of your hands when held in a single hand. As with most M4/AR-15 AEGs, this grip is compatible with aftermarket M4/AR-15 AEG grips, ideal for customisation addicts!

The battery compartment is inside the crane stock, accessible by squeezing the two tabs at the toe of the stock together, after which you can lift the butt plate off, remove the battery plug and make use of the stock's built-in battery compartment to house a nunchuck/crane-style battery. Being equipped with the HAL ETU, we are also treated to a Deans/t-plug battery connector, a lower resistance alternative to the mini-Tamiya found on previous Specna Arms CORE AEGs. For the SA-C27, we recommend a 7.4V 1300mAh LiPo crane/nunchuck battery for an easy fit and great performance.

The Crane stock also includes a pair of QD sling sockets, one on each side, allowing for QD sling swivels to be added for a quick, removable sling setup. Conventional sling slots (aka "footman loops") are also present for those who want a two-point sling but prefer the old-fashioned way. The butt plate is also made from grippy rubber, ensuring your SA-C27 doesn't slip off your shoulder at a critical moment.
