Drum spring with constant force is much cheaper and easier to source, also space and weight saving.</p> <h3>Spring spec:</h3> <p>0.1 x 5 x 600mm Constant Force Drum Spring</p> <p>Only done 7 round and 13 round mags.</p> <p>Test shows the 13 round mag's capibilty increases to 15 round.</p> Category: Mechanical Toys
