  • Polymer or Metal versions
  • Modernised design - "Billet" style
  • For M4/AR-15 AEGs

If your M4/AR-15 AEG is a bit scratched up, the Delta Armory Receiver Set for M4/AR-15 AEG will sort that out! This set includes the upper and lower receiver, fire selector switch and front receiver pin, available in high density polymer or alloy construction. If you're working on a lightweight build, the polymer version is ideal. If you want weight and realism, you want the metal version!

Styling-wise, this receiver set is Delta's own design, inspired by real steel "Billet" receivers found on high-end, ultra-modern real steel AR builds. The trigger guard is enlarged and built-in, improving strength when compared to milspec receiver designs, in line with the latest real steel ARs hitting the market. As we might expect, we are treated to a 20mm Picatinny receiver rail running along the top, ready for a red dot sight, scope or iron sights. 

If you're building from scratch, you will need a charging handle, magazine release, dust cover and mock rear pin to complete the receiver itself, along with your internals and pistol grip. While we can make no guarantees, parts from most other brands should fit this receiver without issues. Whether you need a bargain receiver for a scratch build or want to change the build style of an existing M4/AR-15 AEG, the Delta Armory Receiver Set for M4/AR-15 AEG will do the trick!

  • Enlarged bolt handle - Easy to grab
  • For Tokyo Marui VSR-10 sniper rifle & clones

If you are upgrading your VSR platform sniper rifle to the max an enlarged bolt handle can help when it comes to pulling back a mighty upgraded spring! With this in mind, Laylax conceived the PSS NEO Bolt Handle, designed for use with the Tokyo Marui VSR-10. This bolt handle should also fit VSR-10 clone sniper rifles but as with any upgrade parts, modification may be necessary.

The bolt handle and base are constructed from aluminium and the bolt handle has machined grooves to make it easier to grip in wet weather. The bolt handle is also at a turned-down angle to ensure it clears your scope, no matter how big it is. Marked on the handle and base are helpful instructions on how to use your rifle, in case you hadn't already figured that out! The laser engravings read "1 LIFT THE BOLT HANDLE" "2 PULL >>>>>>" and "3 FIRE". Thanks for the help, Laylax!

If you want to restore the factory fresh look to your workhorse AK, this part may be of use. The Rear Sight Block for the CM.04x Series is an original replacement part for AKM and AK74 rifles of the CM.04x series.

The sight block is constructed from alloy and comes with steel pins to mount it, and includes the handguard disassembly lever but does not include the rear sight or the rear sight leaf spring. The surface finish of this part is a rough textured finish which is a close match for the hard-wearing paint applied to Russian AK variants of the 1960s and onwards.

  • 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.
