Classic Army Nemesis DT4 Double Barrel – Cylinder Head (A693P)
The Classic Army Nemesis DT4 Double Barrel Cylinder Head (part A693P) is the OEM replacement cylinder head for the Classic Army Nemesis DT4 double-barrel AEG platform. The cylinder head is the gearbox component that seals the compression cycle between the cylinder and nozzle — a worn or damaged cylinder head directly impacts the air seal quality and shot consistency of the AEG. Replacing with the correct OEM component restores original performance specification.
DT4-specific cylinder head — the DT4 double-barrel configuration uses a unique cylinder and head geometry that is not directly interchangeable with standard V2 or V3 gearbox cylinder heads. For DT4 owners replacing a worn cylinder head or rebuilding the DT4 gearbox, A693P is the correct OEM part reference.
