The TopMax Elaborazioni cylinder is made in Italy in ERGAL 7075 from CNC-machined solid bars, and this allows you to better manage the expansion/shrinkage phases (due to overheating due to rubbing of the O-RING on the walls of the cylinder itself) of the finished product when it works in contact with the O-RING during firing cycles. The expansion/shrinkage memory effect of ERGAL allows the O-RING of the piston head to work tight without unnecessary effort even at R.O.F. high, returning greater reliability and consistency even in shooting

Technical specifications of the cylinder for UMAREX/VFC MP7 AEG GEN1/GEN2:

Outer diameter of the cylinder – 25.50mm,

Internal diameter of the cylinder – 23.85mm.

ANODIZING and POLISHING internal finish, to guarantee the reduction of friction between the contact surfaces, greater smoothness and resistance to rubbing of the O-RING during use.
