HK Army Slide Check Coiled Remote Line, Black

Running HPA through a gas blowback gun gives you consistent velocity and trigger pull all the way to an empty tank, but a straight air line pulls taut the moment the bolt cycles and limits how far you can move from your tank. This coiled remote line solves both problems.

The coil design gives you working range. You can step back, shift position, and let the slide cycle without the line going solid and threatening to yank your quick disconnect loose. The hose expands and contracts with each shot, so the connection stays secure and the blowback action runs undisturbed.

Build. Metal alloy fittings paired with a rubber air line. Built to take the repeated cycling of an active engine without fatiguing.

Compatibility. Works with HPA systems and CO2 bottles. HPA is where it actually earns its keep: velocity stays flat, trigger pull weight is consistent, and you do not have the pressure drop and temperature swing that comes with a single CO2 cartridge. CO2 works fine if that is all you have, but you lose the main advantage of going remote in the first place. Most fields have their own HPA rules, so check in before you play.

It ships as the coiled hose only. You need your own air tank, the engine installed in your gun, and matching fittings on both ends.

Before you buy. Quick disconnect port sizes vary between engine manufacturers, so double check that your engine's port matches this hose before ordering. You will also want to think about how much working range the coil gives you once extended, since different field positions call for different amounts of line.

This is a tethered setup designed for static or semi-static field positions. If you are looking for a primary that covers ground, this is not it.
