Hadron Loki AAP-01 Hop Unit – Black

One piece CNC Alloy construction outer body for total precision, tested with all leading buckings, and good quality un-bridged GBB barrels. The outer body contains the drilling guide for installation into your chosen AAP upper. No need for extra drill guide purchases. We even supply the correct size drill bit for you to use.

The “Loki” locking plate, is a metal laser cut retaining device, which prevents rotation or self-adjustment of the TDC screw during use, and most especially, sustained 35 rounds per second of use.

The Hadron Airsoft Designs “Loki” nub is based upon the awesome H-Arm V2 profile, which is still the king of the Mk23 hop plates. The nub uses RNT (Recessed nub technology). We push the nub from the bottom surface, not the top. This makes the nub more stable and secure during heavy, or light use.

The inner barrel is aligned by the GBB bucking and secured by two nylon-tipped grub screws. Do not overtighten these. The barrel and bucking are placed into the hop unit from the rear after the hole is drilled in the upper. Always check for debris from drilling before assembly.

The “Loki” hop unit has been tested in various carbine kits, including TTI. SRU Vector, AA Mamba, and many others. To drill the TDC hole, simply assemble the upper and bolt in the empty hop unit as per the tutorial video and drill through. Please use a drill press where possible for accuracy.
