ive decided , upon further testin that when my madbull tightbores arrive next week, ( i ordered 2, one for my m4, and one for my mp5sd5) that i will take this CA barrel out, put it in my vise, and bend it in a complete loop, destrying it forever. the stock JG barrel was shooting 2" groups at 25 feet. this one, about 8" groups. complete and utter garbage. when i look through it, it looks all ripply, not even close to being smooth.
i would never wish this heap of crap on anyone...... and the guys at Xtreme Tactics told me "oh, this is what you want! it'll perform much better than the stock barrel" bah, what a crock. the worst 30.00 i ever spent on airsoft......
rant over.....
