I could be wring but i think the laylax/prommy barrels are around that price. If I am wrong, the best best budget barrel I can think of is the madbull V2 like Andrew said. If you really want to save money thoug, you can just polish the inside of your stock barrel with brasso and use the same procedure as in the how to polish your barrel guide, minus the wax. That's what I did with my stock barrel. I have an EDGI barrel but it's a bull barrel so I can't bend it if I want to LRB it, which is why I polished my stock barrel.
