Installation:-

 

Hadron Airsoft Designs "Quark" TDC adjustment wheel replaces the Loki adjustment grub screw. 

When installing the "Quark" TDC adjuster, remove the Loki TDC grub screw. Note:- The metal Loki lock plate can also be removed, if you wish, but the "Quark" works fine with it installed.

Insert the detent grub screw into the "Quark" chassis, with the spring ball pointing into the TDC wheel location. Adjust until the detent spring is protruding into the adjustment wheel cavity.

Affix the "Quark" to your upper with the provided high tensile fixing screw. Do not overtighten and strip the upper.

Insert the adjustment wheel into the "Quark" chassis, and thread into the Loki hop unit.

Check the operation of the hop unit, and "Quark" TDC wheel visually (removing the bolt allows better view of the hop rubber deformation)

If you desire more resistance to the wheel, then the detent adjuster can be tightened. Take care not to overtighten!

Rebuild, and manually cycle the RIF

Test and set up the hop with your chosen high-quality BB's
