diana chaser drop block system ( hpa chaser conversion)

Description

all aluminum , hooks right to the chaser valve rear.. easy installation , takes a regulated tank up to 1800 psi , 13 cubic inch or smaller tank is recommended for pellet path clearance, but maybe something bigger will fit.
tested to 2000 psi underwater .. no leaks .
Easiest installation possible , no drilling , no tapping , no measuring, no pinning the valve, no extended valve needed  ..bare aluminum sanded, no fancy finish..
this probably makes a lot more sense on the chaser rifles than the pistols , ask questions.
video for installation , its childs play
