All of my friends use the Tear Drop... Its a pretty nice barrel, quiets the gun down a little, but its still loud. Shoots pretty nice, sort of cleans itself when paint breaks in it. I have used the Tear Drop on a bunch of guns, including my M98, and I own the CP one piece... I really do like the CP better, its quieter then the Tear Drop, I love the price... Its only like $50 which is quite a deal... And its pretty darn accurate, Shoots B.E. paint like a charm
The CP Barrel is considered the poor mans boom stick.
