SP Max FLow 88/45
BOA Snakebite .688 12"
Finish is excellent. Various bore sizes were available. Mine is a .688.
Some say weight. The main weakness is they are no longer produced.
Excellent barrel. I use this with an adapter in my Emag without problems (The barrel is threaded for a cocker). Most of what you will find are brass or nickel not stainless. They are polished extremely well and are very quiet. If you get a chance to pick one up, do so. You won't regret it.
As I said before. If you find one grab it. They are excellent barrels.
