Lonex G&G/CA VER7 cylinder head, aluminum

Lonex GB-01-60 cylinder head for G&G and Classic Army Ver. 7 gearboxes. The cylinder head also has a double seal to improve tightness. The end that comes inside the cylinder also has a padded rear wall, which the piston head hits. This is intended to reduce the piston stroke and quieten the operation of the mechanism.
