Shoots through breaks
None that i have found.
If u have a budget below 100$ this is the barrel to go with it shoots very straight. Its also very quiet and it shoots through breaks. I got the 16in because it is so quiet and that is such an atvantage. Because if u go to high ground and get a good hideing spot u can just shoot away and no one will kno were u are. First time i used this barrel i sat up on a hill and hide in a bush a picked of 3 people an the whole time they were screaming were the f*** is he.
this is a good barrel and it has a good price. it has everything u need in a barrel. The only barrel i would buy instead of this would probable be a flatline because of the flat arc and distance.
