Over a year ago, I got myself the TTI VSR trigger system, and I was very impressed. My opinion was that it is the best trigger on the market. Anyway, I saw they had a new hopup chamber out and it looked as though it was really good value for money. So I got one. I have not seen any other reviews on this chamber and so I thought I would write one up.
You can get the hopup chamber from WGC

First Impressions
As most of you will notice, this looks very similar to the famed Action Army chamber. It is even the same colour. But this chamber is better for several reasons. Obviously, it has an external Top Dead Center hopup adjustment dial. This dial is very nice to use, and it makes changing your hopup a very quick process. The dial also has an allen screw that you can adjust to increase the tension of the clicks.
Another big difference is that 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 hopup 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 hopup 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.
True Top Dead Centre: Also, this comes with a proper Top Dead Centre. So, the nub comes down evenly compared to other brands of chamber.
Installation
1. Insert Drilling guide
2. Put the screw in that holds the drilling guide in the correct position and then drill through
3. Cut or file any burrs
4. Put black spacer guide over barrel and put bucking on. Then insert barrel assembly into chamber and tighten Allen screws on either side.
5. Put in the hopup nub parts (This is the Top Dead Centre Hopup. It Rocks)
6. Secure nub in
7. Insert Hopup assembly into outer barrel
8. Screw in mag well block and then put adhesive on outer barrel.
9. Push dial assembly onto sticker and screw in the dial.
10. Adjust hopup until accurate and you are done
Conclusion:
Installation took me about 15-20 minutes and was very easy. Anyone could do it and the instructions that TTI have made are very clear. The hopup is obviously very easy to adjust and the clicks as you turn the dial, are nice and precise too.
The volume of the rifle had dropped a bit as well. This made me very happy because when sniping, we all want to be as elusive as possible. In saying this, I do think that people will get varying results as different branded rifles and cylinders, can vary slightly in length or fitment.
The air seal I got from this chamber was excellent, and when installed, the accuracy was superb. With the external adjuster and the rubber sound absorber on the hopup chamber, I think that this has set the standard. Not to mention it is at a really good price compared to others. I know that there are a few other chambers coming out with the external adjuster, but none of them can lessen the volume of your rifle, and so, for this reason alone, I highly recommend this chamber over others.
