I bought a S&W M&P 15-22 years ago when I lived in NJ.
Threaded barrels on guns that dangerous are verboten due to the dangerousness they add to the already dangerous guns.
We have since moved to Florida and I am free to make my guns as dangerous as I please. I'd like to suppress my 15-22.
If any of you happen to have a threaded take-off barrel you may have swapped out for something more high speed and wish to sell it, I'm your guy.
Let me know what you have.
