Product Description

Features

  • Lightweight glass-reinforced nylon polymer construction
  • Durable CNC 6061 aluminum magazine catch
  • HPA valve is made from heavy duty 1215MS free cut steel
  • Allows you to use HPA and M4 AEG magazines on your Airsoft pistol
  • Designed to keep BBs in until manually released unlike other adapters
  • Tapered threads ensure a tight seal
This adapter enables you to utilize High-Pressure Air (HPA) and M4 AEG magazines on your Hi-capa Airsoft pistols. To make use of it, you'll also require an M4 AEG magazine, a paintball air tank equipped with a low-pressure regulator (0-140 psi) and a HPA line with Foster quick disconnect. The standard operating pressure for green gas stands at approximately 120 psi depending on temperature conditions. We advise operating a pistol at pressures nearing this range and refraining from exceeding 140 psi. Keep in mind that higher pressures could potentially lead to excessive wear and damage within the airsoft pistol's internal components.

Our recommendation is to choose a high quality M4 AEG magazine with strong springs for achieving optimal and consistent performance. It's advisable not to leave the magazine fully loaded with BBs for prolonged durations, as this might cause the spring to fatigue and result in performance deterioration. In cases of worn AEG magazine springs, we recommend replacing them with superfeed springs.

Manufacturer: CTM

'Modification of Green Gas and CO2 magazines to use aftermarket HPA fittings and valves will void all included warranties due to the potential risk of damage from exposure to High pressure and misuse.'

"Pros:
-Really durable and doesn’t feel cheap
-No mag play and no feeding issues
-Keeps most bbs in the hi capa after switching mags only losing 2-3 BBs per mag switch
-lightweight
Cons:
-Out of the box it Had a leak at the threads of the connector but was easily fixed with some teflon tape and worked fine right after that
- there isn’t a flush fit between the hi capa mag and the adapter which sucks but doesn’t affect performance

If you’re looking to get into hpa but don’t want to spend much this adapter is great but might need alittle bit of work if it leaks a bit. It’d really durable and light weight and I don’t even feel it there while I’m holding my gun.

"My First Hi-Capa adapter
I used WE-Tech mags because that's what I had

Pro's:
Works pretty well
Green gas tap if you know what you are doing
Body is Durable

Cons:
M4 mags didn't seat all the way (I used Lancer M4 Mid Caps)
Gas screw would not seat all the way and leaks, gap in between the mag and the mag adapter. Leaks from the screw. Leaks were stopped with a bunch of teflon tape and tape.
Had to screw the gas reservoir screw so tight where it stripped, and still leaked

Overall do not use with WE-Tech mags, you might get better results with a Tokyo Maruoi mag though. Maybe. You gotta find out on your own
