First of all the barrel itself is beautiful. the quality of workmanship is obvious. the packaging and barrel bag also very impressive. the accuracy of the barrel is better than any i've ever shot. i cannot speak to the fact that the barrel is suppose to self clean after a barrel break. i've put about 3 cases through it and have not yet had a break. i have noticed after a day of play the barrel has had residue on the inside(i suppose due to oil on the paintballs). that has not affected accuracy. the only reason i noticed is because i always wash my barrel after play. people say not to use a barrel swab on carbon fiber. i use a pull-through squeegee and it works great.
Awsome barrel. i know the price is high but if it's the last and only barrel you'll need then in my opinion it's worth it. so .......do not get this barrel if you're ever gonna play against me. otherwise get it.
