Description
Classic Army Nemesis DT-4 Double Barrel Cylinder (A694M)
This is the double cylinder for the Classic Army Nemesis DT-4 double-barrel M4, part number A694M. The DT-4 fires through two inner barrels at once, and the cylinder is part of the system that supplies the air to both. This is the OEM replacement part made to suit the DT-4.
The cylinder is listed as an OEM replacement with O-ring seals and a rigid design.
About the part
In an AEG, the piston moves forward inside the cylinder to compress air and push it through the cylinder head and nozzle to the hop-up. A damaged or worn cylinder can lose compression, which shows up as a drop in power or inconsistent shots. Fitting the correct OEM part restores normal operation.
Fitting
Fitting this part requires opening the gearbox, which takes care and some experience. Remove the battery and magazine, make sure the gearbox spring is relieved before opening the shell, and note how parts are laid out before removing them. Because the DT-4 internals are not the same as a standard gearbox, it is worth taking photos as you go. Inspect the new part before fitting, and if you are not confident working on gearboxes, our workshop can fit it for you.

Compatibility
Made for the Classic Army Nemesis DT-4 double-barrel rifle. It is not intended for standard single-barrel AEG gearboxes. Check your rifle model before ordering.
Care and maintenance
When the gearbox is open, clean old grease and dirt from the surrounding parts. Lightly lubricate O-rings with silicone oil and use a suitable grease on gears and moving parts, avoiding excess grease near the air seal. Use good quality seamless BBs and remove the battery when the rifle is not in use.
Who is it for?
This part suits DT-4 owners and techs who need to replace a worn or damaged cylinder with the correct OEM component.
Please note: Supplied as the part only. Professional installation is recommended if you are not experienced with gearbox work.
