Limited edition Matrix
Red Trinity reg
Chrome back plate
Black Lightning drop and Chrome CP asa
This will take your pressure and pretty much chop it in half. I know the operating pressure of the Matrix is freakishly low already, but when shooting at really fast speeds it is easy to chop balls and you NEED the Trinity reg. Since I bought my Trinity, i've had no chopping problems, including the time where i held the ball halfway in the chamber and fired like a disgruntled postal man.
It makes it easier to adjust velocity if you have a big drop forward like mine in the way.
Hmm, im not sure.... the price is perfect, it makes the gun look cool, i guess the only bad thing is that they don't come stock.
Definately buy this reg if you own a Matrix. A Matrix with a trinity reg is probably the only thing you'll ever need for a gun, it works better than you'd expect.
