Hadron Airsoft G17/G18 TDC Cover
Allows external adjustment of the G17/G18 Hop up. With good quality rubber, use 0.3 to 0.5g bb.
Hadron took the expertise and knowledge from the design and manufacture of the Mk23 TDC series, and applied this to the Glock G17 and 18. This gave numerous engineering challenges. After 18 months of testing and changes, development and feedback, they have a game changer.
Remove slide, remove existing outer barrel assembly. Open hop unit barrel assembly, and remove the hop wheel.
Re-assemble with a quality bucking, Flamingo or Maple Leaf Autobot 50 series. Maple Leaf Crazy jet barrels work exceptionally well in the setup.
Insert an H-plate or Fang if required (ideally use for 0.4 and above)
Rebuild, and when fitting the Hadron outer assembly, ensure to nip up the lower securing grub screw. DO NOT OVER TIGHTEN.
Once the inner/outer are replaced in the upper slide, add the grub screw to the TDC.
Refit the upper to the lower, and check slide to TDC grub clearance.
