Quark TDC Hop-up adjuster for chamber LOKI for AAP-01

You have been asking since the day Loki was announced, for an external adjuster.

However, product refinement is driven by feedback, and strenuous testing.

The product testers loved this, and the ease of adjustment with gloves on. They, however, wanted as low profile as possible for their uses.

It's taken a little time to get this kit as low profile and functional as possible, while making it affordable.

Hadron Airsoft Designs "Quark" body is a CNC made alloy low profile sculpted design, which bolts onto the AAP-01 upper (Round style uppers), using the upper rail front mounting hole.

The Quark features an external click adjustment system, which is provided by a spring detent installed into the "Quark" chassis. This provides a tactile feel to any adjustment.

Installation:

1. Hadron Airsoft Designs "Quark" TDC adjustment wheel replaces the Loki adjustment grub screw.
2. 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.
3. 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.
4. Affix the "Quark" to your upper with the provided high tensile fixing screw. Do not overtighten and strip the upper.
5. Insert the adjustment wheel into the "Quark" chassis, and thread into the Loki hop unit.
6. Check the operation of the hop unit, and "Quark" TDC wheel visually (removing the bolt allows better view of the hop rubber deformation)
7. If you desire more resistance to the wheel, then the detent adjuster can be tightened. Take care not to overtighten!
8. Rebuild, and manually cycle the RIF.
9. Test and set up the hop with your chosen high-quality BB's.
