I have 2 Phantom Springfeeds for sale, 1 10rnd and 1 15rnd. Both are reversable so they can be mounted forward or backwards. I believe that they use the stock Phantom feed screw but I'm not positive and I don't have a Phantom to check on. No screw is included.
The only trade would be for a gloss red Dye UL barrel that is Freak bored.
This is what I'm using one for.
