Specna Arms SA-P22 PRIME™ MK16 M-LOK M4/AR-15 AEG

If you're seeking premium performance straight out of the box, set your sights on the Specna Arms SA-P22 PRIME™ MK16 M-LOK M4/AR-15 AEG! A rock solid full metal build on the outside, kitted out with some of the best internals we've ever seen in a mass-produced Airsoft AEG, the SA-P22 is at the cutting edge of external platform design with its M-LOK handguard, ergonomic pistol grip and pre-installed SAAS angled foregrip, and inside, things get even better!

Inside, the PRIME series really brings the heat, equipped with the Specna Arms Dark Matter Brushless motor straight out of the box. This is a rare thing to find pre-installed in anything but a Bolster Tuned custom AEG, though the good stuff doesn't end here! Also inside is a 6.02mm tightbore inner barrel, Specna's latest Magnus™ HOP-up chamber and Helium™ HOP-up bucking, 16:1 high-speed CNC gears, a steel quick change spring guide, 8mm J-CAGE bearings, CNC aluminium cylinder group parts, CNC aluminium nozzle, a reinforced tappet plate and reinforced polymer piston with a full rack of steel teeth. This truly is a platform you'll never need to upgrade!

Starting at the front of this powerhouse of a platform, we find a pre-installed 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.

The handguard of the SA-P22 is a perfect match for the real steel SMR rail used on the MK16, offering a 20mm Picatinny rail at the 12 o'clock position as well as M-LOK slots at 3, 6, and 9 o'clock, with additional slots at offset angles. The upper rail mates seamlessly with the receiver rail, allowing for optical sight setups of any length to be mounted, including red dot sight and magnifier combinations. The use of M-LOK negative space attachment slots makes the front end super light and agile, and despite its length, the SA-P22 can be swiftly manipulated easily, ideal for modern shooting doctrine.

Close to the receiver, the handguard has what appears to be QD sling sockets on either side. In our tests, we found these sockets to be non-functional, at least with the QD swivels we had handy. If you plan to use a QD two-point sling setup with the SA-P22, we recommend using the QD sling sockets built into the pre-installed SAAS Angled Foregrip, as these are fully functional. Also pre-installed on either side of the handguard are 20mm Picatinny rail adapters for M-LOK, allowing you to run 20mm accessories on the sides, reposition the rails to any of the other M-LOK slots or remove them entirely for a sleeker look.

As we come to the receiver of the SA-P22, we can take note of its familiar M4/AR-15 style layout, making it an easy transition in terms of training if you're already accustomed to running an AR platform in-game. The charging handle is an extended example, positioned at the top rear of the receiver, which can be pulled back to reveal the rotary HOP-up unit, known by Specna as the "Magnus" HOP-up chamber.

A rotary design with the "Helium" HOP-up bucking pre-installed, the Magnus HOP-up unit is the latest design for the M4/AR-15 AEG and is known for allowing finer increments of adjustment for more precise HOP-up application, and holding its setting for longer under the vibrations of full-auto fire. This HOP-up unit is paired with a steel 6.02mm tightbore inner barrel, giving the SA-P22 spot-on accuracy right out of the box, with little left to improve!

The fire selector is of the standard M4/AR-15 layout, with a 3-position selector switch located above the pistol grip on the left side, offering safe, semi-auto and full auto. The selector has a 90-degree throw between each fire mode, allowing the control to be used swiftly while minimising the chances of accidentally knocking the selector out of place. Being equipped with either the ASTER II™ or HAL¹ MOSFET, these fire modes can be programmed with a wide variety of alternatives, from burst mode to binary trigger and more!

The Specna Arms SA-P22 PRIME™ features a skeletonised flat trigger. This enhances the military aesthetic of the AEG and complements the modernity of the rest of the Airsoft rifle, not to mention the easily slappable design, perfect for snappy double taps in semi-auto. The pistol grip features diamond checkering on either side and a linear texture on the front and back, providing excellent gripping qualities for both gloved and ungloved users. As with most M4/AR-15 AEGs, this grip is compatible with aftermarket M4/AR-15 AEG grips, ideal for customisation addicts!

The magazine release is located on the magazine well on the right side and is well within reach of the trigger finger for right-handed users. This mag catch is right-hand optimised but can be used by lefties as well with a bit of practice. The right side of the upper receiver has the usual M4/AR-15 features, including a mock forward assist button, mock brass deflector and the dust cover which conceals the mock bolt and HOP-up adjuster.

At the rear of the receiver, we are treated to an ambidextrous sling plate which offers two sling points on the left side and one on the right. The sling plate is ideal for single-point slings, but can also be paired with a front sling mount if you prefer a two-point sling setup. Being constructed from steel allows the sling plate to take the weight of the SA-P22 easily, and provides confidence that the plate will never fail and dump your gorgeous rifle into the dirt.

Following the sling plate, we come to the 6-position M4/AR-15 buffer tube, which is constructed from aluminium for a great balance of strength, realism and low weight. The stock of the SA-P22 is mounted over the buffer tube and features an rubberised cheekpiece for greater comfort, a thick rubber butt plate with aggressive gripping texture, a low profile adjustment lever to reduce snags and a QD sling socket on either side, both of which are fully functional. The stock has 6 positions of adjustment, making it suitable for any body type or loadout and includes an quick detach butt plate for easy access to the battery compartment.

Internally, the Specna Arms SA-P22 PRIME™ has a lot to boast about. The gearbox shell spine has been reinforced to ensure that it doesn't break, this is a well-known fault with V2 gearboxes and it is good to see that Specna Arms have addressed this issue and taken matters into their own hands to make sure that it won't be a problem with this premium line of PRIME™ AEGs.

Inside the reinforced shell we find a plethora of premium parts such as CNC 16:1 ratio steel gears running on 8mm J-CAGE bushings, a reinforced piston with a full rack of steel teeth, a reinforced tappet plate for reliable feeding, and a CNC aluminium piston head, cylinder head and nozzle for maximum long term durability. The cylinder is also CNC machined from steel, as is the spring guide.

To match these parts we also find Specna Arms Dark Matter Brushless High-Speed Motor, this insane component gives the SA-P22 a truly insane rate of fire when on full auto and the brushless design ensures that it won't overheat as easily, even after long periods of constant full auto.

Gate ASTER II Bluetooth™

The Gate ASTER II is one of the most advanced ETU/MOSFET systems on the market, granting the user endless shooting customisation based on their preference. It connects to the GCS (Gate Control Station) app via Bluetooth®;this is where the vast range of settings can be adjusted to make this assault rifle perfect for your play style.

It supports the high rate of fire of the SA-P22 PRIME™ and reduces the overheating and wear on internal components, plus, the trigger sensitivity and pre-cocking can be adjusted, so you can be sure that you are always first to fire in a duel. This nifty MOSFET also allows you to program fire modes to replace semi and full auto with a range of options, including burst modes of various durations and binary trigger.

Specna Arms HAL¹ ETU

The HAL¹ ETU is ideal for skirmishers who prefer the simple life, with improved trigger response and alternative fire modes on the side! The HAL¹ adds a whole lot of functionality into the mix, with programmable fire controls, 6 levels of pre-cocking adjustment and 5 levels of trigger sensitivity adjustment, exactly what you need to get the most out of the PRIME build without overcomplicating things.

Available fire modes include 3 or 5-round burst, binary trigger, AUG mode aka two-stage trigger, semi-auto only and sniper delay, giving you loads of options for how you use your SA-P22. All fire modes are programmable through the trigger and fire selector, and instructions can be found here.

If you're after a primary at the top tier of handling and performance, the Specna Arms SA-P22 PRIME™ MK16 M-LOK M4/AR-15 AEG belongs in your arsenal. Ultra modern both inside and out, the SA-P22 is ready to be dressed up with accessories and bring the pain downrange!
