  • Alloy/CNC alu construction
  • For Tokyo Marui & CGS M4/AR-15 ZET GBBRs
  • Fits standard M4/AR-15 AEG magazines
This adapter is not covered for leaks under your usual 12-month warranty. 

If you're planning on running your GBBR through winter or fancy mag dumping like it's going out of fashion without the dreaded "cooldown" effect, the Army Armament HPA P30 Adapter for M4/AR-15 AEG Magazines; CGS/MWS System is what you need! 

A collaborative project between Army Armament and T8 Systems, this HPA adapter is designed for the Tokyo Marui M4/AR-15 ZET System and the CYMA CGS M4/AR-15 GBBR series, allowing standard AEG mags to be used along with a High Pressure Air (HPA) power source. The set includes both an EU and US HPA connector but you will need an airline, HPA bottle and regulator to run this adapter. 

The advantages of using HPA when performance is concerned include the elimination of FPS fluctuation due to the "cooldown" effect, resulting in improved shot-to-shot consistency and improved accuracy down range, especially under rapid fire. If you're already running HPA you probably have all the bits to make this work already and experience shoulder-thumping recoil through the frosty months!

  • HPA Engine for V2 gearbox
  • TITAN™ II V2 HPA Version required
  • For M4/AR-15, SMG-5 & G3 AEGs

If you're done with AEGs and want to revamp your build for HPA, the GATE PULSAR D Dual Solenoid HPA Engine is a fantastic option. Designed for Version 2 AEG gearboxes, the PULSAR D is designed to work with a GATE TITAN™ II V2 ETU (HPA Version), giving you unlimited advanced programming options along with the bob on consistency, top-tier accuracy, killer rate of fire and wealth of tuning opportunities HPA builds are known to provide.

The set includes the complete engine but will require a V2 gearbox shell, V2 trigger and TITAN™ II ETU HPA Version to complete the build. When compared to the original and more affordable PULSAR S, the PULSAR D offers a higher FPS range, universal compatibility with AEG nozzles, less precision required in the assembly of the build and impressively high air efficiency, using only 0.7 PSI per shot on average at 90 PSI with a 0.8L air tank.

The PULSAR D also has the edge in accuracy and versatility over the simpler single solenoid PULSAR S, being suitable for any build objective, from CQB monster to DMR dominator. As with all internal upgrades, we only recommend this engine to those who are confident working on AEG and HPA internals, but if you're ready for the PULSAR D, you're sure to be impressed!

  • 30rnd Capacity
  • Green gas/HPA magazine
  • Fits CYMA CGS & TM ZET M4/AR-15 GBBR

If you want a magazine for every season and you're running a CGS or TM ZET system GBBR, get one of these! The CYMA 30rnd Green Gas/HPA Gas Magazine for CGS/MWS GBBRs is compatible with both CYMA CGS and Tokyo Marui ZET system M4/AR-15 GBBRs and has a green gas fill valve and a HPA line attachment point on the rear of the STANAG style body.

The mag can be loaded through the feed lips at the top of the magazine, though this can be challenging with a standard speed loader without a GBBR adapter. As with the original TM and CYMA GBBR magazines, these mags include the bolt stop components which lock the bolt open at the end of a mag, and each mag holds 30 BBs. 

To use this magazine with HPA lines, instead of swapping the whole magazine when out of ammo, you can purchase separate quick-detach BB tubes. By pulling the tab rearwards on the bottom of the magazine you can remove the internal BB tube and then insert another one. This means that you can carry way more BBs without the hassle of large magazines occupying your rigs!

Whether you feel like using gas or HPA, this magazine has you covered for all occasions and is the perfect all-year-round gas magazine, just make sure to get some separate BB tubes if you plan on using HPA!
