Classic Army Nemesis DT4 Double Barrel Gear Set – A691M
The Classic Army Nemesis DT4 Double Barrel Gear Set (part reference A691M) is the correct replacement or upgrade gear set for the Classic Army Nemesis DT4 double barrel AEG platform. The DT4 is Classic Army’s unconventional dual-barrel bullpup AEG, and its gearbox configuration requires the correct gear specification to maintain the correct cycling and timing for both barrels. Standard gear sets designed for conventional AEG platforms are not compatible.
For DT4 owners undertaking a gearbox rebuild or addressing gear wear after extended use, the A691M gear set provides the correct OEM-spec components for the DT4 gearbox without improvising with incompatible parts. Classic Army OEM parts ensure correct fit and function within the DT4 gearbox specification.
