5KU Airsoft

If you are working on a multifunctional platform, ready for both indoor and outdoor skirmishes, then this is it! The 5KU 11.5" Aluminium Outer Barrel For M4/AR-15 AEG is compatible with most M4/AR-15 AEGs and is constructed from aluminium for a perfect balance between low weight and high strength. 

The barrel is threaded at the tip with common 14mm CCW male threading, meaning you can mount the most common muzzle devices on the market with ease, including tracer units, suppressors and flash hiders in various styles. Also present are grooves in the underside to allow a gas block or M4/AR-15 triangular front iron sights to be mounted, though this is not essential. If you need your M4 to be ready for any situation then this will get you halfway there, but don't forget you'll need a matching inner barrel too! 

If you're looking for a new outer barrel to make your M4/AR-15 AEG perfect for woodland skirmishes, the 5KU 16" Aluminium Barrel for M4/AR-15 AEG is a fantastic option. Constructed from aluminium with 14mm CCW male threading at the tip, this 16-inch outer barrel includes pin holes for mounting an M4/AR-15 front sight/gas. 

The 5KU 16" Aluminium Outer Barrel for M4/AR-15 AEG has the standard Tokyo Marui AEG outer barrel fitting at the rear, meaning it should fit the vast majority of M4/AR-15 platform AEGs but won't fit NGRS M4s or GBBRs. Whether you're extending your barrel for the improved long-range effect or you just want your Airsoft rifle to look rather long and intimidating, the 5KU 16" Aluminium Outer Barrel belongs on your M4 AEG, Just remember to pick up a matching inner barrel!

If you're building out your AK to match the latest real steel builds, the 5KU 20mm Picatinny Rail Mount for Zco AK handguard is essential. Based on real steel Zco-style red dot risers, this aluminium component fits replica Zco-style handguards such as the 5KU Lightweight Zco-style Lower Handguard. It will only attach to these styles of handguards due to the unique attachment interface.

Atop the riser is a section of 20mm Picatinny rail, perfect for mounting a red dot that matches the modern Russian design. If your modern Zco-style AK requires optic space for longer-range engagements, the 5KU 20mm Picatinny Rail Mount for Zco AK handguard is the piece of equipment for you.

If you are working on your CQB build you must be looking for an extremely short outer barrel, and this one certainly is that!

The barrel is threaded at the tip with common 14mm CCW male threading, meaning you can mount the most common muzzle devices on the market with ease, including tracer units, suppressors and flash hiders in various styles.

If you need your M4 Airsoft rifle to be shorter this will get you halfway there, but don't forget you'll need a shorter inner barrel to match!

This Airsoft Suppressor is a replica of the PBS-1 which is designed for AK Platform rifles in the real world, but will work with anything that has either a 14mm CCW or 24mm CW Thread. This means it will fit to any replica with a standard thread, but can also directly thread to the Outer Barrel of AK models that have the appropriate thread (such as LCT branded AKs).

If your primary weapon is boasting a 1913/20mm Picatinny stock setup you now have some fresh new stock options thanks to 5KU! The 1913/20mm Picatinny Folding Skeleton Stock w/Folding Butt Plate is designed to mount to any 20mm Picatinny rail, but please, don't mount it to your handguard!

The stock itself is constructed from aluminium with weight reducing cuts throughout, and the folding/mounting mechanism is constructed from steel to provide the prerequisite strength. This stock is ideal for super compact setups with its folding butt plate, and its raised cheekpiece provides superb sight alignment. This stock can be mounted directly to the Sig Air MCX or MPX, or any AEG with a 1913/20mm stock adapter, providing an ultra-compact solution when folded, with full functionality when deployed! Get this on your MPX, it deserves it!

Used by the UKSF, this replica suppressor doubles as a tracer unit and attached to your 14mm CCW outer barrel and provides an ultra-realistic muzzle device experience. Featuring a clean, well-weighted alloy design with an aggressive low profile front muzzle.

If you are an AK rifle fan you may be feeling left out with all the modern, westernised spitfire tracer units entering the market right now, but 5KU are here to get you into the muzzle flash game! The 5KU PBS-1 Spitfire Tracer Unit is styled after the Soviet-era PBS-1 AK suppressor and includes apparatus to mount the unit on either 24mm AK threads or more common 14mm CCW male threads found on almost all Airsoft rifles. If you are after a more stealthy look for your AK, with the added benefit of being able to use tracer BBs and dazzle the enemy with an ultra-bright muzzle flash effect, the 5KU PBS-1 Spitfire Tracer Unit is what you need!

If you want to add a grip to your railed AK platform but want to keep it Russian, this is the grip you need! The 5KU Aluminium Russian Compact Foregrip; 20mm Picatinny is constructed from aluminium with a ribbed external design to improve handling and add traction. Inside the grip, we are also treated to a storage compartment designed for CR123a batteries, though you can store other items inside (we use ours for sweets). 

This grip is based on the popular Zco-style vertical grip often seen on styled-up AK platforms with other Zco furniture. If you want to add modern attachments to your railed AK but want to keep it purely Russian, this grip belongs on your gat!

If you are working on your CQB build you must be looking for the shortest barrel out there, and right now, this is it! The 5KU 7" Aluminium Outer Barrel For M4/AR-15 AEG is compatible with most M4/AR-15 AEGs and is constructed from aluminium for a perfect balance between low weight and high strength. 

The barrel is threaded at the tip with common 14mm CCW male threading, meaning you can mount the most common muzzle devices on the market with ease, including tracer units, suppressors and flash hiders in various styles. Also present are grooves in the underside to allow a gas block or M4/AR-15 triangular front iron sights to be mounted, though this is not essential.

If you need some tracer action in your life but you run a shotgun, the 5KU Tracer Choke for Shotguns is what you want! This aggressively styled tracer unit mimics real steel shotgun breaching chokes and provides muzzle flash and tracer functionality to any Airsoft shotgun with an outer barrel with a 22.5mm or 23.5mm outer diameter.

The tracer mounts via 4 grub screws on the collar using friction, and we recommend ensuring the screws are properly tight and the unit is mounted straight before testing it out. The activation button is located underneath the rear collar, as is the USB Type-C charger port for the integral rechargeable battery, requiring the rear collar to be unscrewed to access. Available modes include tracer with muzzle flash, tracer only and muzzle flash only, ideal for those who want all the fire but none of the tracer and those who want tracer functions without lighting up the room and giving their location away. 

Two variants of the Tracer Choke are available to suit different shotguns; one for 22.5mm outer diameter barrels and one for 23.5mm. Make sure you measure up before ordering! If you grace CQB sites with a trusty shotgun at your side, the 5KU Tracer Choke for Shotguns is a must!

If you want a red dot sight on your AKS-74U but aren't a fan of the Russian side rail, 5KU has what you need! The 20mm Rear Sight Rail for AKS-74U AEG/GBBR is designed to mount over the rear iron sight of AKS-74U rifles, both the AEG and GBBR variety, providing a length of 20mm Picatinny rail measuring 8cm approximately. 

The part is constructed from aluminium to provide a great balance of strength and low weight and should fit most AKS-74U Airsoft guns on the market, though some may require slight modification. If you want to mount a red dot sight for faster target acquisition but still want to be able to fold your stock for tight quarters, the 5KU 20mm Rear Sight Rail for AKS-74U AEG/GBBR is the key!

For all you serious SMG5 lovers out there in need of a tracer, this is the one for you! Featuring robust full alloy construction with a smooth, brushed finish for a lightweight build and sleek design.

The tracer unit sports a fluted design, which in the real world equivalent would help displace heat, however even though this is an Airsoft replica the fluted design does have other practical benefits such as reducing weight to prevent your weapon from becoming too forward heavy.

Featuring a tri-lug muzzle attachment method, the tracer can be quickly attached and detached on the fly if you need to switch up your shooting style during gameplay and it can be used on other replicas with a tri-lug device (see special instructions).

The AK series of rifles is famous for many things, but having the best iron sights is not one of them. The AK Rear Sight Rail For Red Dot Optics from 5KU replaces your AK's rear iron sight but retains basic functionality with its built-in emergency backup sights while providing the option to mount a red dot sight!

Designed specifically for Micro red dot sights, the 8 20mm Picatinny rail slots provide plenty of room for larger red dots but it would look rather silly. It's your AK though, make the purists cry if you feel like it!

This stubby Foregrip is constructed using CNC Machined 6061 Aluminium for a superior finish, and is designed to provide a stable aiming position whilst also remaining compact and reduce snagging on your own equipment. It has an integrated 20mm Rail attachment and will easily fit to RIS/RAS Rail Systems. There is also a secret storage compartment inside the grip, accessed by unscrewing the base. If you're looking for a Russian style Foregrip for your AK or even Western Rifles, the 5KU Aluminium Russian Grip will fit the bill nicely.

An Aluminium constructed Rail Mount for AKS-74U Platform Airsoft Replicas, which will install to the Rear Ironsight Block and provide a 20mm RIS/RAS Rail for installing a Red Dot Sight. If you own an AKS-74U and you want to start decking it out with bells and whistles, then this is an ideal place to start.

If you want your AEG to send shivers down the enemy's spine, if anything can do it, this muzzle brake can! The 5KU DTK-2 Russian AK Muzzle Brake is patterned after the real steel Zenitco DTK-2 and is a squat design with a pair of massive ports on each side and two smaller ports on the bottom.

The real device is designed to reduce felt recoil and compensate for muzzle climb and is generally seen on carbine and SBR length AK rifles, though the 5KU example will fit both 14mm CCW and 24mm CW Russian threads, making it compatible with practically any Airsoft gun on the market. If you want to change up the looks of your rifle and make it that bit more menacing, this brake will do it!

A compact and solid Foregrip for 20mm Rail Systems, which is constructed from CNC Aluminium and is based upon a Russian grip design that is most often seen on AK Platforms, but will provide a stable platform for aiming any Rifle that has a 20mm Rail.

5KU brings us an imitation of the Russian SF 9x19 flash suppressor made high quality CNC aluminium, known as the KP-9. With a large, rounded and aggressive aesthetic, the very front of the suppressor sports cut grooves and port holes to conceal muzzle flash in the real-world equivalent.

Most often seen on SMGs such as AK47s, KP9s, MP5s and Scorpions, this Airsoft replica suppressor utilises a 14mm CCW female thread so it can be fitted to any thread or adaptor that sports the corresponding male 14mm thread. With a padded foam interior that muffles your shots, this suppressor gives you what you need to sneak around and get those stealth kills in style!

A QD sling plate for M4/AR15 AEGs which have a sliding stock with a buffer tube. This plate comes with a steel QD sling swivel, which can be installed in the sockets on either side of the sling plate, or in any other QD sling socket on your weapon. Simply hold down the button on the swivel, pull it away to release the swivel from the plate. To re-install the sling loop, simply hold the button down, insert into the socket, and release the button. This allows for both left and right-handed use, and quickly detaching your primary weapon or altering your sling configuration without having to use tools or waste time!

If you're looking for a new outer barrel to change up the length of your M4/AR-15 AEG, the 5KU 10.3" Aluminium Outer Barrel for M4/AR-15 AEG is a fantastic option. Constructed from aluminium with 14mm CCW male threading at the tip, this 10.3-inch outer barrel is styled to match the profile of real 10.3" CQBR barrels and includes pin holes for mounting an M4/AR-15 front sight/gas block at the "carbine length" position. 

The 5KU 10.3" Aluminium Outer Barrel for M4/AR-15 AEG has the standard Tokyo Marui AEG outer barrel fitting at the rear, meaning it should fit the vast majority of M4/AR-15 platform AEGs but won't fit NGRS M4s or GBBRs. Whether you're shortening your barrel to a more CQB-friendly size or giving it a bit more length for more long-range effect, the 5KU 10.3" Aluminium Outer Barrel belongs on your M4 AEG!

If you are looking for a suppressor you can quickly and easily remove as and when it suits you, these are what you are looking for! Available in 3 different lengths to suit any situation, the 5KU Special force suppressor gives a serious and aggressive look to your AEG and alters the muzzle report to make you harder to locate!

If you are looking for a Tracer Unit with Russian styling the KP-9 Spitfire Tracer Unit from 5KU is one to keep an eye on. This device is based on the real world MPI KP-9 flash suppressor used by Russian Special Forces with their PP-19-01 SMGs and is ideal for any 9mm style Airsoft SMG but will fit any Airsoft rifle with a 14mm CCW male threaded barrel.

This KP-9 isn't just about the looks either, inside you will find a Spitfire Tracer insert which illuminates green tracer BBs and provides a realistic muzzle flash effect each time you fire. The unit can be operated in flash only, tracer only or tracer and flash mode, giving plenty of options for the aggressive, the realism focussed and the more stealthy playstyles out there. Whether you run a PP-19 AEG or you are looking for the most menacing looking Spitfire tracer unit out there, this will do the trick!

If you are building a modernised AK rifle and you want the sneaky special forces look the PUTNIK suppressor from 5KU would be the best thing for it. This suppressor is based on the real steel Zenitco PUTNIK and can be attached to any Airsoft AEG with 14mm CCW male threads via the included steel adapter, and its built-in threads allow it to be fitted to 24mm CW male threads found on some Airsoft AKs. The suppressor is constructed from alloy and has a foam filling which will slightly dampen the muzzle report of your AEG or GBB, and the suppressor can also be disassembled if you want to add an inner barrel extension. For the modern suppressed AK look there is no better suppressor!
