Specna Arms SA-PH21 PRIME™ M-416 14.5" AEG

Whether you're a fan of the 416 or you simply need a mission-ready AR platform with the special forces look, the Specna Arms SA-PH21 PRIME™ M-416 14.5" AEG is one to watch. A hefty full metal replica of one of the most popular real-world platforms for special forces worldwide, the SA-PH21 suits an SAS, Delta Force, Navy SEAL and practically any other special forces loadout perfectly. What sets this 416 aside from others is its innovative pre-upgraded internals you simply won't find in other out-of-the-box Airsoft AEGs. Get ready to be impressed!

Internally, the Specna Arms SA-PH21 PRIME™ has a lot to boast about. The AETHER V2 gearbox shell spine has been reinforced to get ahead of a well-known weakness with V2 gearboxes operated at high-performance parameters. It is great to see that Specna Arms has addressed this issue, to ensure the premium PRIME™ AEGs are as reliable in the long term as they are fantastic shooters on the field.

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 drive this impressive gearbox setup, we also find the Specna Arms Dark Matter™ Brushless High-Speed Motor. This insane component gives the SA-PH21 an impressive 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. To keep these high-quality parts in check at high-performance parameters, PRIME™ AEGs are available with either the Specna Arms HAL MOSFET or the GATE ASTER II Bluetooth MOSFET pre-installed. The HAL is ideal for Airsofters who like to keep things simple and the ASTER II is what any techy skirmisher who loves playing with settings to achieve the optimal setup needs!

Starting at the tip of the 14.5-inch "carbine length" outer barrel, we find an M4/AR-15 birdcage flash hider mounted to 14mm CCW male threading. The outer barrel is constructed from alloy to provide a strong backbone and keep the tightbore inner barrel nice and straight for perfect accuracy. The barrel profile also perfectly matches the real steel 14.5" 416; full marks for realism so far! If you want to mount a tracer unit, suppressor or alternative muzzle device, all you need to do is unscrew the flash hider and mount your preferred device, thanks to the common 14mm CCW threading at the tip of the barrel.

The front iron sight is a fixed front post with "wings" on either side of it to keep it protected from accidental bumps. The sight is constructed from alloy and is not adjustable, as it is welded onto the wings. This sight design is taken straight from the legendary G3 and MP5 platforms, offering the option to aim quickly using one of the wider apertures on the rear sight while offering 3 additional apertures for different engagement ranges. These sights are excellent but are also rail-mounted and removable, giving you the option to replace them with flip-up sights or remove them entirely.

Surrounding the outer barrel, we have a CNC aluminium quad 20mm Picatinny rail, a perfect match for the original, iconic 416 rifle. At the 3, 6, 9 and 12 o'clock positions, we have full length 20mm Picatinny rails, ready for any 20mm accessories you choose to add to complete your mission. All this rail space is excellent for people trying out new loadouts; the freedom of being able to mount common 20mm Picatinny attachments on any side of your handguard allows you to find the perfect setup. The major perk of the 416 style handguard interface is its keyed engagement with the upper receiver, ensuring the handguard will never loosen up and rotate.

The receiver should be a familiar sight to anyone who has handled an M4/AR-15 platform before, constructed from alloy and matching the 416 receiver style perfectly. This includes the more vertical magwell angle, mil-spec flat trigger guard, magazine release fence and raised upper receiver rail. The magazine release is on the right side of the magazine well, with a push-through design just like a standard M4/AR-15 AEG with a textured surface for optimal traction.

The fire selector switch is just above the pistol grip on the right side, offering 3 modes of fire with a 90-degree throw between each. The default fire modes are safe, semi-auto and full auto, but with the pre-installed ASTER II Bluetooth ETU, you have almost infinite fire mode configuration options programmable through the Gate Control Station App. This makes the SA-PH21 as versatile as it is advanced!

The charging handle can be found at the top rear of the receiver and features an extended charging handle latch to provide easy access when wearing gloves. Pulling the charging handle back will pop the dust cover open and retract the mock bolt, revealing the rotary Magnus™ HOP-up unit on the right side. The HOP-up allows you to adjust the amount of backspin applied to your projectiles and tune the SA-PH21 for different ammo weights, looking for the flattest possible trajectory. When you've completed your adjustments, you can slap the "ping pong paddle" style bolt release catch on the left side of the receiver to drop the mock bolt with a satisfying metal-on-metal "clank".

Up top, we have a 20mm Picatinny receiver rail with a preinstalled rear iron sight. The rear sight offers the choice of 4 different aiming apertures, designed for engagements at different ranges and in different ambient lighting conditions. If you prefer to run an optical sight you can loosen the screws with an Allen key on the left side of the iron sights and remove them to access the full length of your receiver rail.

At the rear of the receiver, we come to the steel CQD-style sling plate, which offers ambidextrous functionality with single-point slings; perfect for left or right-handed shooters. The steel construction practically guarantees no matter what you choose to mount to the SA-PH21, the sling plate will be strong enough to support the weight.

To the rear of the sling plate, we come to the M4/AR-15 buffer tube, which is constructed from the same strong, high-density polymer used for the receiver. The buffer tube offers 6 positions of stock adjustment and boasts a low-snag design to keep mobility high. The adjustment lever is located on the bottom and is well concealed inside the design, allowing the stock to be lengthened and shortened to suit the environment and play style. We don't recommend using the visible loop sling points on the stock as they are made from polymer, we would recommend using the slit in the middle of the stock instead.

The battery compartment is inside the HK-style sliding stock, offering plenty of room for Crane/nunchuck configuration batteries. To access the battery compartment you can either remove the stock entirely by pulling the adjustment lever out and sliding the stock off to the rear or remove the butt plate by rotating it counterclockwise and pulling it off. Inside, you will find a Deans battery connector to which you mount your chosen battery. We recommend a 7.4V 1450mAh LiPo in crane/nunchuck config for easy installation and perfect performance. The Deans connector has the advantage of being smaller and offering lower electrical resistance when compared to the mini-Tamiya, and we are always happy to see more Deans connectors appearing on out-of-the-box AEGs.

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-P19 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-P19. All fire modes are programmable through the trigger and fire selector, and instructions can be found here.

Whichever variant you decide to go with, you're in good hands with a Specna Arms SA-PH21 PRIME™ M-416 14.5" AEG! With a high-quality and authentic full metal build, pre-upgraded internals to rival the best and some serious technology keeping everything running smoothly, this is an AEG you'll never need to upgrade!
