Bore kit for the M4A1/SR16/M733 TM standard replicas

Description

Drilling kit for the M4A1/SR16/M733 TM standard replicas

A set consisting of a cylinder, a cylinder head and a piston head is specially manufactured for the TM M4A1/SR16/M733 replicas so that their capabilities can be increased by enlarging the diameter of the main air system, resulting in a higher muzzle velocity without having to replace the main spring with a stronger one. This also has an effect on the service life of the replica.

Every part included in the set has been additionally reinforced. This makes the set perfect for working with stronger springs.

The double sealing of the cylinder head enables a very good seal. In conjunction with the reinforced gasket also included in the set, a better seal is achieved than with the standard parts.

The ball-bearing mounted directional piston head has a special shape and ensures low-noise operation.

A main spring M120 or stronger is required for the set to function properly

The set contains:

- a cylinder head with double gasket and enlarged diameter,
- a directional piston head with an enlarged diameter,
- a cylinder with an enlarged diameter,
- a sealed nozzle,
