A-5, starfire bolt, E grip, expansion chamber, double trigger, compressed air 3000 psi
pro ball is good but the best is (especially in the woods) is combat 68
Very accurrate, shoots far, looks great, very quiet.
May need o adjust velocity due to long length.
I love this barrel.
It is the best part ive out on my gun so far.
My kills have gone up three hundred percent.
Alot of my friends think im basically cheating because of its length.
Now i take all my kills from about fifty plus feet.
This is the ideal barrel for a sniper due to its accuracy and stealthyness.
Smart parts has done it again, same with the linear barrel which is the same but looks more for speedball.
