I could tell you, if I ever want to buy a silencer, I have no intention of making my own. First, it's a PITA to do a trust and NFA paperwork, so I would want something top-of-the-line for my efforts. Not some oil filter clamped onto the end of a barrel. I neither have the skills nor the equipment (nor a place to keep the equipment needed) to make a top-quality suppressor. Because suppressors have little resale value, I am sitting this one out - too much money, too much trouble, no real ability to get your money out of it - too rich a toy for me.
