Mancraft AEG to HPA Conversion Kit – PDiK

PDiK, short for Pneumatic Drop-in Kit, is a flagship offering within Mancraft’s HPA engine lineup for AEG rifles. Key benefits of this HPA conversion kit include user-friendly installation and compatibility with a wide array of rifles, eliminating the need for modifications. This simplifies the installation of each HPA system, making it a quick and straightforward process that requires minimal skills and knowledge. No more dealing with shimming bearings, springs flying around, or gears misaligning with the gearbox holes. With Mancraft, it’s as easy as opening the shell and placing a single-component engine inside. Whether you’re in search of an M4 HPA engine or an M16 HPA conversion kit, Mancraft has you covered.

How Mancraft HPA engines works?

Mancraft HPA engines use high pressure air power (pneuamtics) to move parts (mechanics) and go through a 3-step shooting cycle:

1. Positioning: Align the nozzle and BB in the hop-up chamber.
2. Charging Fill the cylinder with the pressurized air.
3. Releasing: Release the air through the nozzle.

This burst of compressed air expands in the barrel, pushing and accelerating the BB in front of it. Because Mancraft uses a cylinder instead of a hammer and spring valve like GBB systems, the gas amount is the same in every shot. That’s why the BB’s speed – FPS (Feet Per Second) – between each shoot can be extremely consistent and accurate. It’s quite common to find Mancraft DMR and sniper rifles with 1 fps deviation.

Mancraft PDiK installation guide

Here is a general guide and manual for installing the Mancraft PDiK HPA Engine. For more detailed information, feel free to reach out to us directly or check additional resources on YouTube. Each Mancraft engine for AEG rifles with a TM standard V2 gearbox is meticulously designed to seamlessly match your existing receiver. However, if your rifle’s manufacturer made alterations that deviate from the TM V2 standard, you may need to trim corners or surfaces to accommodate our standardized shell. Fortunately, such adjustments are uncommon, and in over 95 out of 100 cases, the engine fits without any modifications.

1. Disassembly:
   – Carefully disassemble the rifle until the existing gearbox and motor are accessible.
   – Keep all parts and screws organized on the side.
   – Take photos of the disassembly process for reference during reassembly.
   – Ensure the battery is disconnected, and the piston is disengaged from the compressed spring.
2. Optional: Retaining Old Trigger:
   – If you plan to use your old trigger, remove it along with the tension spring from the original AEG gearbox and set them aside.
3. Opening HPA Shell:
   – Unscrew all six hex bolts to open the HPA shell. Note that they come in two different lengths.
4. Trigger Installation:
   – Install the trigger. The tension spring is optional and can help reduce the time between shots based on the spring stiffness.
5. Optional: Fire Selector Assembly:
   – Optionally install the fire selector assembly. The engine will function without it, but the rifle will be locked in SEMI only mode.
6. Pneumatic Tube Installation:
   – Feed the pneumatic tube through the motor hole into the pistol grip.
7. Closing the HPA Shell:
   – Close the HPA shell by securing it with the six hex bolts.
8. Engine Reinsertion:
   – Insert the engine back into the receiver.
9. Reassembly:
   – Follow the reverse of the disassembly steps to reassemble all parts except the AEG gearbox and motor.
   – Lead the tube out through the bottom of the pistol grip.
10. Tube Adjustment:
    – Cut the pneumatic tube to the appropriate size.
    – If using a standard HPA line, cut it a few centimeters behind the grip and install a 6mm-US adapter at the end.
    – If connecting the rifle directly to the pressure regulator, do not cut the tube.

Other components of the HPA setup for AEG and Spring Rifles:

HPA tank

HPA tanks are available in various sizes and shapes to accommodate different needs. It’s important to consider the size of the tank, as smaller tanks will require more frequent refills. If you don’t have easy access to a scuba diving shop or a personal filling station with a large scuba tank, opting for a larger HPA tank may be beneficial to minimize refilling inconveniences.

Pressure Regulator

To maintain pressure and optimize performance, you need a pressure regulator. While any airsoft or paintball low-pressure regulator (80-150psi) works, we highly recommend the original Mancraft Regulator. It simplifies setup by eliminating the need for extra fittings and ensures peace of mind, preventing overpressure and potential conversion damage. You can find our Mancraft Pressure Regulators here.
