Product Description

AIRTECH STUDIOS HOP UP TDC CONVERSION KIT FOR KWA QRF MOD 1 ROTARY CHAMBER

the airtech studios tdc (top down centre) carriage converter is engineered for the kwa qrf mod2 rotary hop up chamber to radically improve the hop up application within the chamber. this system provides optimal pressure on the bb, leading to increased precision over long distances.

Hop Up Compatibility

this kit can be used with all hop up types.
perfectly suited for r hop and flat hop configurations thanks to a carriage system that applies hop up pressure perfectly downwards for more uniform pressure on the bb.
result: increased accuracy over long distances.

Why TDC (Top Down Center)?

using a top down center hop up is a highly sought after feature in airsoft because it maximizes friction on a bb.
while third party chambers exist, they risk double feeding, feeding errors, and irregular air compression.
this kit provides a superior upgrade option by utilizing the original hop up chamber, specially designed for kwa qrf mod series replicas.

M-Nub

airtech studios tested many types of m nubs for strength, durability, and shape retention under intense pressure, resulting in an optimal version.
