  • 6.03mm Tightbore inner barrel
  • Programmable MOSFET - 2rnd Burst ready!

If you're into modern Russian platforms and value realism, the ARCTURUS AK-12K AEG Rifle; Optical MOSFET will definitely put a smile on your face. Like other ARCTURUS AK platforms, this beast is made almost entirely from steel, with a stamped steel receiver and top cover, steel outer barrel and milled steel front sight block, giving you the authentic heft a proper AK replica needs. While the externals are absolutely bomb-proof and finished flawlessly, the internals of the AK-12K Optical MOSFET version are equally impressive!

Inside, you'll find a 6.03mm tightbore inner barrel paired with the ARCTURUS AK rotary HOP-up unit, giving you what you need to send BBs downrange accurately and consistently. The gearbox is a version 3 fitted with CNC 18:1 steel gears running on 8mm ball bearing bushings with a new nozzle made from CNC machined technopolymer, promising enhanced airseal qualities and reliable feeding in the long term. 

Star of the show is the ARCTURUS Optical MOSFET, providing the ultra-realistic 2-round burst mode just like the real AK-12 along with the ability to program the fire controls for burst modes of different durations, adjust pre-cocking and trigger sensitivity. The MOSFET also improves electrical efficiency which translates into a faster trigger response and raised rate of fire, especially when paired with the pre-installed 23K RPM high torque motor. If you're searching for an ultra-modern AK replica which is built like a tank and extremely well-equipped straight out of the box, the ARCTURUS AK-12K AEG Rifle; Optical MOSFET is one to watch!

Description

If you love the feel of realistic steel, the ARCTURUS AK-12K AEG Rifle; Optical MOSFET will give you what you need! Pairing the legendary ARCTURUS AK build quality with pre-upgraded internals, this AK-12K is as realistic as it gets with an almost entirely steel external build and 4 selector positions, including the super satisfying 2-round burst mode. 

Inside, a 6.03mm steel tightbore inner barrel coupled with a new rotary HOP-up design provides superb accuracy and constancy at long range. The version 3 gearbox is rocking 8mm ball bearing bushings for smooth, friction-free functionality and a new CNC technopolymer nozzle to enhance air seal qualities. Paired with the optical MOSFET inside, this AK-12K is a real beast in the performance department with the option to program the fire selector for burst mode, binary trigger, pre-cocking and much more!

The AK-12 improves on the original AK design by adding 20mm Picatinny rails on the handguard and newly designed receiver top cover, a fourth fire selector position for 2-round burst and a more modern tangent/aperture hybrid rear sight, curing most of the criticisms operators have of the original Russian design.

This means the AK-12K is ready for optical sights, tactical flashlights, laser aiming modules and much more with no extra adapters, parts or upgrades needed, unlike its older brothers. Whether you're going full Spetsnaz or working on your PMC loadout, the AK-12K from ARCTURUS would make a fantastic primary, especially this, the Optical MOSFET-equipped version!

Starting at the tip of the outer barrel we can find an AK-12K style muzzle device, which follows a similar design to the M4/AR-15 birdcage in function with a series of ports around the circumference, but with the classic Russian aesthetic which fits the AK-12K perfectly. If you are a bit more of a Spetsnaz type of player you may be thinking of mounting one of those lovely new PBS style tracer suppressors, the good news is this won't be a problem thanks to the 14mm CCW male threading concealed beneath the flash hider. The outer barrel is constructed from steel, which is a great start, though there is a lot more steel to come on this rifle!

Moving rearwards we come to the front sight/gas block, which is constructed from steel with a textured surface finish matching the hard-wearing paint used for Russian manufactured AK rifles. This is a nice touch for realism, as nothing gives the game away quite like an AK front sight looking a bit too smooth and "Airsoft-y". The front sight blade can be adjusted up and down to set the elevation and is protected on either side by protective wings built into the front sight/gas block. At the bottom of the gas block, we can see a bayonet lug which is another nice added touch for realism, but we doubt you'll need this for skirmishing! 

Following the front sight we come to the gas tube, which runs parallel with the barrel all the way back to the receiver, with the handguards surrounding it. The gas tube has a slightly different finish to the front sight, which is another awesome detail Arcturus included to distinguish the stamped steel construction of the gas tube from the milled steel of the front sight. Details like this are what separate an Arcturus AK from others, and will really please realism fans!

As we reach the handguard we can take note of something very un-AK-like. The handguards no longer have handguard caps, as they are now free-floated! This may not mean much for Airsofters but it sure makes the difference in the real world, as many blame the handguard design for the AK platform's lower inherent accuracy. Now the AK plays catch up! The handguard includes a 20mm Picatinny rail built into both the top and bottom, allowing for a vertical or angled foregrip to be installed, and saving space for a PEQ laser or tactical flashlight on the top. Either side of the handguard also includes removable 20mm Picatinny rail sections, which can provide extra space for more mission essential kit, or be removed for a slick handguard and some minor weight savings. 

The receiver of the AK-12K is closely based on the original AK design, but with some notable modernisations which equip the AK-12K for 21st-century combat. The receiver and top cover are both constructed from steel and sport realistic markings on either side. The left side of the receiver includes mock rivets and pins in all the correct places, together with "6 Л70" and 5.45x39 engraved below. Over on the right side, we can find the 4-position fire selector, appropriately marked with Cyrillic lettering for each mode, and a "2" for the 2-round burst position. This extra selector position only provides an additional fully automatic position, and does not provide a burst mode but was included on the AK-12K to keep it faithful to the real rifle. 

The top cover is a more modern hinged design, which allows a repeatable and reliable zero with any optical sight mounted to the 20mm Picatinny rail running along its length. This top cover really is rock solid, and feels more like the monolithic receiver of a SCAR than the top cover of an old school AK. The top cover rail is riveted tightly to the top cover itself, guaranteeing no wobble will develop and your optic will sit straight and true.

This rail is one of the best things about the new AK-12 design, and saves you messing around with side rails and various other aftermarket solutions to give your AK some nice glass to aid your goal of sending the enemy back to respawn! Included in the box is a rail-mounted rear tangent iron sight, which can be installed if you aren't using an optical sight, or as a backup in case your main sight goes down mid-battle. This sight functions exactly the same way as the original AK tangent sight, with the added benefit that it can be positioned wherever you need it on the rail. 

The battery compartment of the AK-12K is located beneath the receiver top cover of the AEG and can be accessed by removing the receiver retention pin and pulling the top cover off to the rear. The retention pin can be found at the front of the top cover, and requires the lever on the right side to be rotated 90 degrees counterclockwise when looking at the rifle with the right side facing you. With the lever rotated and pointing upwards, you can now pull the pin out to the right where it will remain captive in the trunnion block. Following this, the top cover can be pulled backwards and removed towards the rear of the rifle. Inside you will find a Deans battery connector to which you connect your battery of choice. We recommend a 7.4V 1450mAh LiPo battery for the best fit in the Arcturus AK-12K. To reinstall the top cover you must index the pins found inside the cover at the rear inside the hooks at the rear of the receiver, after which the pinholes can be realigned and the pin pushed back through and rotated to lock inside its recess in the handguard. 

The HOP-up unit of the Arcturus AK-12K can be found inside the ejection port, behind the mock bolt carrier, and is accessible when the bolt carrier is pulled and held to the rear. This unit is a newly designed rotary style HOP-up for the AK platform, replacing the original slider adjuster design to provide more direct force on the top of the HOP bucking, eliminating lateral movement for greater shot-to-shot consistency, and less side-to-side deviation when more HOP-up is applied.

This device allows you to vary the amount of backspin applied to your BBs and tune the AK-12K for your ammo weight of choice, and the new design shows that Arcturus are not content to leave things as they are and seek to innovate rather than sticking with the tried and tested but potentially less effective slider HOP. Following your adjustment, you can release the mock bolt carrier and let it fly home and enjoy the satisfying metallic "clank" you can only get from a steel AK bolt carrier.

When it comes to the controls of the AK-12K, not much has changed for the latest AK variant which still sports the familiar AK selector position and ambidextrous magazine release located at the bottom of the receiver. If it ain't broke, don't fix it! The selector lever is an extended design featuring an additional tab which allows the shooter to control the selector with the trigger finger, allowing for the AK to be quickly switched from "safe" to "semi" without removing your hand from the pistol grip.

Like the selector lever, the mag release is constructed from steel and follows the standard AK form allowing for left and right-handed use, and the dynamic mag-flip emergency reload if you don't mind damaging a magazine from time to time. The pistol grip is another notable improvement over the original AK. and is an ergonomic design with comfortable finger grooves and a slightly straighter grip angle to allow for more comfortable use when the stock is collapsed all the way. 

As we arrive at the rear of the receiver we come to the folding mechanism for the stock of the AK-12K. This stock offers 5 positions of length adjustment, allowing the rifle to be set up for any body type or loadout, and can also be folded to the left side for storage, transportation or close-quarters work. 

The button to fold the stock can be found on the left rear of the receiver, in the same location as the folding stock button of an AKS-74, and when this button is pressed the stock can be folded to the left where it will automatically lock under spring tension. To deploy the stock from the folded position, all you need to do is grab it and fold it open, avoiding the additional catch of the AKS-74 series and allowing for faster stock deployment with less fine motor movement needed. 

The stock can be adjusted in a similar manner to that of an M4/AR-15, by pressing down the adjustment lever found within the A-frame of the stock. Locating the adjustment lever here means there is no chance of it snagging on your gear and inhibiting your movement in-game. At the front of the stock, we are treated to a QD sling socket which can be used with a QD sling swivel (not included) and the front sling mount to set your rifle up for a two-point sling. 

At the rear of the stock, we can find a rubber butt plate for additional comfort, complete with linear texture to ensure the stock grips your shoulder perfectly for optimal control over the rifle. This butt plate can be removed by pulling the spring-retained pin found near the toe of the stock and sliding the butt plate off its dovetail. Beneath you will find a handy storage compartment within the stock tube of the AK-12K, which is well suited to storing a spare battery, maintenance equipment, or a tactical emergency snack to keep you fuelled on to victory. 

On the inside, this AK-12K is equipped with a high torque motor to deliver the power needed for a swift trigger response and allow for stronger springs to be installed, keeping within the design parameters of the AEG. Like other ARCTURUS AEGs, the gearbox is filled with low-friction parts to increase the lifespan and efficiency of the system. The AK-12K also uses ARCTURUS's rotary AK HOP-up unit which shows incredible potential as the newest HOP-up unit design for the AK platform, coupled with a 6.03mm tightbore inner barrel constructed from hardened steel for enhanced accuracy through its high-quality internal finish and extra rigidity.

The most notable enhancement of the new AK-12K is its pre-installed ARCTURUS optical MOSFET which facilitates the 2-round burst function while also providing improved rate of fire, trigger response and the ability to program the fire controls for burst modes and other advanced functions. The MOSFET also improves electrical efficiency and eliminates the need for certain internal mechanical components, meaning less chance of failure in the long haul and a faster trigger response and rate of fire than you might expect!

If you have the mindset to run a super realistic full metal platform and you're into the AK aesthetic, the ARCTURUS AK-12K AEG Rifle; Optical MOSFET is perfect for you. With museum-quality external construction and impressive internals straight out of the gate, this AK-12K is ideal for all environments as long as your arms are strong enough to wield it!

Special Instructions

Please note, due to the design of the AK-12 scratches will develop in certain areas from normal use. This is unavoidable, and many of our AK-12 AEGs already have these scratches from the factory due to the testing and QC process.

An example of such scratches is the AK "selector lever scratch", a scratch which develops beneath the AK style fire selector from use.

These scratches are part of a realistic AK look and will develop over time regardless of whether they are present initially or not. Please consider this carefully before making your purchase.
