GBBCustom 3D Printed TDC Hop-up Chamber (AEG Hop Conversion)
|Compatibility||KWA & PTS LM4 Series|
Top Down Center (TDC) mod for the LM4 just got a whole lot easier! TDC is a must for KWA LM4's as it greatly improves accuracy and distance. The 3D printed HOP-UP chamber was designed around TDC, and It eliminates the risk of ruining your stock hop-up chamber when doing the mod.
Stock KWA LM4 hop-up tensioner wears quickly. No worries, this hop-up design replaces stock hop-up tensioner with a steel set screw that maintains positive contact with the hop-up bucking.
- Uses Standard Aeg Style Hop-up Bucking. (We recommended G&G green bucking or Prometheus purple bucking) *hop-up and barrel sold separately.
*Complete TDC mod requires a drill press to cut a small hole on top of the lm4 receiver to reveal the set screw for hop-up adjustment. Further modification may be required.
