I bought a suppressor from them and even paid the $25. (+ shipping) for the tool to take it apart. The tool fits yet I could not get it apart. I called and was connected with the the owner. I was told that I must be some kind of weakling. Anyhow, the use of the "f" word as well as G.D. every other word coupled with accusing me of shooting .22lr through it (a big no no) tells me that I will not be spending any more of my cash with them. I have talked to others and they have had trouble with T.I. also.I hope this saves somebody from wasting their money.
