This is the M93RFS.

① Barrel Spacer
With the genuine part, the inner barrel retracts, the nozzle is blocked by the packing, and air is released to fire. However, the nozzle blocking the packing and the air release happen almost simultaneously, with very little margin, making the air's engagement with the BB unstable. This spacer pre-retracts the inner barrel by 0.5mm compared to the genuine part, stabilizing the air's engagement with the BB and improving accuracy.
Applying force along the direction of the laminated lines can cause breakage. Even if it breaks, it will not affect functionality.
② Barrel Block Spacer
With the genuine part, the barrel exit side is loose, making the trajectory unstable. This part fixes the inner barrel at the barrel block side, stabilizing the trajectory.
Please adhere it inside the outer barrel, in front of the shaft before the chamber (around position 5).

Because the inner barrel is retracted by 0.5mm, the hop adjustment screw will also retract and become difficult to turn. You will need to file the outer barrel and slide. Alternatively, the effect of the barrel spacer is limited, so you may be satisfied with the normal state.

The press used to access the inner barrel is:
