Blue 98 custom
Flatline barrel system
Easily adjustable, does what a stock is supposed to do.
I have used this stock for a few months, and it works nicely. Since I occasionally play the role of sniper on our team, this comes in handy and makes my gun look cooler. It is adjustable so that somebody from the size of a midget to a giant can use it with ease.
If you really want one and can find it for under 50$. I would buy it.
