Couldn't load pickup availability
Pickup currently unavailable at Skirmshop Spain
This polymer Bolt B (part no. 133), manufactured through a precision CNC process, and the steel screw (part no. 134) form an extremely lightweight set specially designed for the M4 (T.Marui) GBB. While the polymer Bolt B is 13 g lighter than the original part, it offers good durability with greater elasticity than the original component. As a result, this polymer Bolt B weighs only 55% of the original part and helps increase bolt cycling speed while minimizing friction around the buffer tube.
