ZCI Stainless Steel 3/4 Cylinder (Type II)

Solid cylinder, good finish (no rough edges and good internal polish). Fits G&G, G&P, and JG V2s without any issues or gaps with the gearbox shell. It sealed extremely well with the G&G and JG cylinder heads (I tested it on all three before leaving it in the G&G). On the G&P aluminum one I did need to put some tape because it was quite loose (it was easy to separate both and leaked some air). Great prices again from clandestineairsoft.
