These CNC machined aluminium upgrade piston heads have been designed & manufactured In the United Kingdom specifically to replace the original green plastic cup-seal (Part No I-8) in the Tanio Koba USP .40 Tactical SD GBB which is prone to breaking when green gas is used, these piston heads are also compatible with the Tanio Koba VP70.
The Lees Precision Engineering piston heads consist of a CNC machined 2014 T6 aircraft grade aluminium and a standard metric size O-ring to increase durability when used with green gas and also provide a better seal than the original cup-seals.
*Please note that the price is for one piston head only.
