Proto barrels are manufactured with premium 6061-T6 high-grade aluminum and honed to .690 and 8 micron finish. Proto barrels are available in two models, single tube construction and two piece configuration. Additionally, straight porting makes the Proto barrel a quiet and most accurate addition to your gun.
Available in black, red, blue and clear. Sizes are 12" and 14" lengths for single tube and 14" and 16" lengths for two piece. Made for most markers.
The Proto 2 Piece Barrel is newer, so it should be commonly available, both new and used.

Accurate, quiet, looks
I have only used this barrel in a few games so far but i really like it and its alot better than the stock one. i have shot through it marbs, premiums, and stingers and they all shot ok, as long as u get undimpled ones. the barrel is 16 inches so for that length on a cocker it is really nice, doesnt slow the ball down at all and i really like it.
Ireally like this barrel but if u have the money to get it get a pipe kit, i should have done that but this barrel is really good too.
THis barrel requires some pretty good paint like Premium, Marballizer, X Balls, some PMI paint
A little heavy for a barrel
This is a great barrel. I have used less than a month and I am already in love with it. The Proto barrel has awesome accuracy and you can get a lot of distance with it. When I went to Skyline I was shooting all the way across the field without barely any tilt to the barrel. It comes in 14in and 16in so you can fit it to your needs. Also it comes in four great colors, (blue, red, clear and black). The only problem I have is I still think it is too heavy. I would rather have an Ultralight or a Freak. They are much lighter. It is still a very good deal for it price.
My conclusion is that it is a very good barrel, but if I were you I would buy an Ultralight or a Freak.
