Description
Classic Army Nemesis DT-4 Double Barrel Cylinder Head (A693P)
This is the double cylinder head for the Classic Army Nemesis DT-4 double-barrel M4, part number A693P. The DT-4 fires through two inner barrels at once, and the cylinder head is the part that seals the front of the cylinder and directs the air towards the nozzles. This is the OEM replacement part made to suit the DT-4.
It is listed as a dual cylinder head that seals around the cylinder for compression, with O-ring seals.
About the part
A good seal between the cylinder head, the cylinder and the nozzle is essential for consistent power. A damaged cylinder head or perished O-ring can let air escape, giving low or inconsistent shots. Fitting the correct OEM part restores the seal.
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 head with the correct OEM component.
Please note: Supplied as the part only. Professional installation is recommended if you are not experienced with gearbox work.
