Advance TDC Top-Down-Center Trolley for: Maxx Model Rotary Chamber (New Gen. All)

Distributeur Airtech Studios

Product Description

The TDC (Top Down Centre) Trolley is designed for the Maxx Model Hop-up Rotary Chamber to incorporate the use of the extended M-nub to distribute the maximum of hop over a chambers hop-up window to improve the accuracy and consistency of the shots fired. This in turn ensures the patch can maximize its appliance on the BB for the most stable and uniform spin for the much desired R-hop performance.

FAQ Frequently Asked Questions

1. What is the difference between the original trolley and this?

We extended the length of the trolley from 3.8mm originally to 5mm to cater for a wider spectrum of inner barrels in the market.

2. What if I dont need the full 5mm length?

Thats ok, you can install the M-nub and when its pushed down it it will apply the required top-down pressure onto the bucking and BB.

3. What if i need exact M-nub size?

2x M-nubs are provided so you cut the length to size by a exacto knife to the precise size you need.

4. Can this be used on all Maxx Model hop up units?

Only the new gen. If you need it for the older version, we have that too on our website.
