  • Steel construction
  • Folding stock
  • Railed receiver

This one's for all you AK lovers looking to treat your rifle to a new receiver and stock. Constructed entirely from durable steel, this will undoubtedly give you AK a nice sturdy feel with a good weight balance. The stock itself is skeletonised to keep the weight balance and to allow it to fold into the receiver and lock in place with a latch.

The receiver has all the hallmarks of a classic AK body, with its signature level style mag release and angular trigger guard and is even complete with the iconic AK dovetail side mount, to which you can attach the tactical accessories of your choice.

Whether your looking to spruce up your AK47 with a new receiver and folding stock, or fancy creating some Frankenstein's monster of a rifle by attaching this to a non Russian rifle (we won't judge), this solid piece of gear is a great buy at the price.

  • High density polymer construction
  • Extended mag release - Easy reloads
  • For Delta Armory DA-P series GBB pistols

If you're running a Delta Armory DA-P series EU17 GBB pistol and want to reload faster, this is the key! The Delta Armory Extended Magazine Catch for P-Series GBB is constructed from high density polymer, designed specifically for the DA-P series but potentially compatible with other Gen.3 style EU17 frames (no guarantees though!).

This extended magazine release features a textured surface for optimal grip in all weather and is much wider than the standard mag release, making it easier to reach for smaller hands. The set includes the entire mag release assembly other than the spring, though the original mag release spring used in the DA-P series is a perfect fit. A super affordable upgrade to make pistol handling much easier, this Extended Magazine Catch is just what you need to speed up your reloads!

  • Aluminium construction
  • Ambidextrous functionality
  • For TM EU17 Gen.4 and EU19 GBB pistols

Adding a cocking handle to your pistol might seem a bit much, but in the modern-day and age of primary pistols becoming more and more popular the pistol needs to give up some of its concealment characteristics to become more than "just" a sidearm and compete in the modern CQB site. The Tactical Cocking Handle from CowCow is an ideal solution, providing a protrusion on either side of the slide to allow the pistol to be cocked more quickly and easily, even allowing for one finger cocking from either side! This cocking lever adds a whole lot of functionality but is more compact than competition optimised designs, allowing it to still be used with most tactical holsters whilst reducing snags. This cocking lever replaces the back plate of the slide on your TM EU series pistol.

  • For Tokyo Marui based AK-47S AEGs
  • Underfolding stock required

If you own an AK-47S underfolder AEG and you want to elevate its realism, a metal body kit is the key! The CYMA Metal Receiver for TM AK47S AEG is compatible with the CYMA CM.028S and Tokyo Marui AK-47S AEGs and will also fit others as long as they use the Tokyo Marui external design and have an underfolding stock.

The receiver is designed to match the original AK-47S "milled" receiver style, complete with weight-reducing cutouts at the front on either side, steel mock pins for some nice extra detail and engraved Cyrillic fire selector markings, an appropriate nod to realism. At the rear of the receiver, there are cutouts so an underfolding stock can be installed, and there are no conventional stock tangs on this receiver so it is not compatible with the full stock or side folding stock variants of the AK-47 AEG. If you want your AK-47S to be as its creator intended, this metal receiver kit is what you need!

Its ambidextrous design makes it perfect for lefties or those who often find themselves swapping between shoulders on the battlefield.

This charging handle has been designed to mimic the style of popular real steel charging handles and features a skull design between its wings, aggressive! If you fancy a new style for your M4, a new charging handle is the perfect way to add some personality and flair, the 5KU Ambidextrous Charging Handle is a great choice!

Compatibility-wise, this kit is designed for CYMA AK AEGs of the CM.04x and Cm.05x series using the VFC external construction style. It may fit other VFC-style AKs but won't fit AKs based on the TM AK-47 AEG (CM.028, CM.5xx, CM.03x & JG AKs) nor will it fit AKS-74U AEGs. If your AK needs a 21st-century facelift to compete with modern designs, kit it out with the CNC Aluminium MK3 M-LOK Chassis for CYMA AK AEGs from 5KU!
