I think you need a special tool to remove the barrel. As far as fluting to look cool..sure! Thats the whole reason for all of this!
Search on the forum here and you will find how to make a barrel removal tool out of PVC 3/4 id pipe.

I'd rather see if smith would do it. That way they couln't give you any crap about ruining your warranty. I know guys on here have sent their's in with barrel threading and they didn't void the warranty. But, you never know when that could change. I'm with whoever said we should bug smith about getting our barrels threaded for free. Maybe even tell them we'll pay for shipping. Give them the old, " Your customer service has a great reputation how about blah blah blah etc"....... STRENGTH IN NUMBERS!!!!!
ETA: With the way M&P15-22's are selling, I wouldn't be the least bit suprised if Tactical Solutions came out with a aftermarket threaded BBL for it.
Look up the Magnuson Moss Warranty act for a little light reading.
Just to clarify. S&W cannot just void your warranty for having the barrel threaded. What they CAN do is deny a warranty claim IF the problem is directly related to the modification that has been made. Of course, they can also deny a claim if you have abused/misused, disabled any safety features, or made illegal modifications.

Personally, I'd like to be able to buy a pre-threaded BBL direct from S&W, but I'll probably end up sending it in to ADCO, or Gemtech to have it threaded. Both of them are already tooled up for M&P15-22's.
