The TTI Airsoft TDC Hop-Up Set is a TDC-style hop-up chamber designed for the Tokyo Marui VSR-10 series airsoft sniper rifles or compatible models like the Novritsch SSG10. This hop-up chamber is made of CNC construction and is more robust compared to the stock hop-up chamber.
It has an external Top Dead Center hop up adjustment dial. This dial is very nice to use, and it makes changing your hop up a very quick process. The dial also has an allen screw that you can adjust to increase the tension of the clicks.
The chamber also has a black rubber shock/sound absorber at the rear end of the chamber. This rubber shock/sound absorber has three purposes. The first purpose for the rubber absorber is that it can lessen the sound signature of your rifle. The reason it does this is because when the piston slams into the cylinder head, the cylinder head then slams into the hop up chamber. Thus, making a loud slamming noise. This can make a reasonable difference in volume on some rifles. So, it is well worth getting just for this reason. The second reason for the shock/sound absorber is to stop the hop up chamber from getting scratched from the cylinder head. And, lastly, it can reduce the vibrations that are carried through to the barrel. Thus, helping with accuracy.
