Bore Up cylinder set for M4/M16 type replicas
The front of the piston head and the adjacent cylinder head surface are made of special, elastic and very durable material that cushions the blow and, thus, contributes to the heighten durability of the part. Thanks to this design, the set has similar sound muffling properties as the sets of silent cylinder and piston heads.
Set includes reinforced parts:
- chromium cylinder
- metal cylinder head with double seal
- bearing piston head
- gastight nozzle.
