HADRON AAP-01 TDC LOKI Hop-Up Unit - Silver

LOKI TDC Hop-Up Chamber for AAP-01 / AAP-01C GBB by Hadron Airsoft Designs

The professional-grade LOKI TDC hop-up chamber is custom-designed for AAP-01 and AAP-01C GBB pistols, offering superior stability, accuracy, and long-term reliability. The entire body is machined from a single block of CNC aluminum and includes an integrated drill guide hole – no external jig needed. A precise 2.5 mm drill bit is also included.
The chamber features a unique LOKI locking plate to prevent the TDC screw from self-rotating – even at extreme fire rates of up to 35 RPS. The screw stays firmly in place without constant re-adjustments during play.
Included is a custom RNT nub (Recessed Nub Technology), inspired by the proven H-Arm V2 for MK23 pistols. This bottom-pressured nub provides stable and accurate contact with hop-up buckings. Fully compatible with premium hop-up rubbers and unbridged GBB inner barrels.
The LOKI chamber has been tested in various carbine kits, including TTI, SRU Vector, AA Mamba, and others. Installation is straightforward thanks to the included drill bit and instructions – even beginners can handle it.
