This polymer Bolt B (part No.133), which is made by precision CNC process, and steel screw (part No.134) are extreme lightweight set that is specially made for M4 (T.Marui) GBB. While the polymer Bolt B is 13g lighter than the orginial part, this polymer Bolt B has good strength with higher elasticity than the original part. Therefore, this polymer Bolt B has only 55% weight of the original part, and it assists the bolt to increase the recoil speed and minimize friction around the buffer tube.
