Hadron MK23 Socom NBB M-TDC Cover TM, STI, ASG - Twin screw
Allows adjustment of the Mk23 Hop up, externally, without losing the slide movement feature. Fits in 2 minutes. Highly Effective. M-TDC is the new design from Hadron Designs and allows in this form, two possible locations of hop pressure application by clicking out the twin adaptor, and rotating 180 degrees. The M-TDC is a modular design, so, by changing the plates (click out), then clicking in the single screw plate (separate item), the M-TDC chassis can utilise single screw pressure advantages.
