ok i went to the warehouse where the people make this product and they are all nice people. I live in Phoenix, Arizona and their warehouse is like 3 miles away so i had no wait time and i could check out the product. These people were like so help ful. They only had one insert in stock so they let me have it, the insert had a blemish in it but he said that i could use the insert and when i pick up the others i can get a new one. HOW SWEET IS THAT !!! This barrel is really accurate and makes my gun quiet. Also the red finish on my barrel looks good on my red impulse.
Nothing yes i just tested it. Kind of sucks that they were all outta inserts but its all good. I spoke to the guy that runs the place and they are actually going to make a larger place to manufacture the barrels and inserts so they should be getting things in stock faster.
This is the best barrel on the market. Also probably the cheapest. If i were you i would buy this barrel right now. The only reason im giving it a 9 is because they were out of a lot of the inserts but that is ok since i live right down the street from them :)
