T91 Wolf A1 combat rifle piston system similar to the Belgian FN FAL automatic rifle use of short stroke piston drive design, Taiwaneses 205 Armory modularized the new design .

Combined the:
Gas Cylinder Head(10-1),
Piston Rod(10-2),
Piston Rod Spring(10-3),
Spring Bushing(10-4),
Buffer Spring(10-5),
Rod Guide(10-6),
together insert into the Piston Tube(10-7), collectively referred to as "drive mechanism", also known as "piston pipe group quick release system."

But the transmission mechanism does not have FN FAL automatic rifle intake control knob for gas adjustment. The design also target to simplify field maintenance for the soldiers, compared with the old T65 rifle series which contain too many small parts and difficult to dissamble.

To remove the drive mechanism, simply unlock the exposed gas cylinder head before pulled entire single module out.
After the gas cylinder head is part of the piston pipe, which contains a piston rod (catheter and connecting rod designed to be linked together as one piece, but can be freely move indivisualy).

There is a buffer spring on the outside of the piston rod, with a set of cushion spring seats after; and followed by a connecting rod. All the above parts are load into the long piston tube, And then combined with the gas cylinder head. Under normal use, the F marking of the locating pin of the transmission mechanism should be facing upwards after assembled.
