Up for sale is a Rick Kuehl .22 lr M-16 upper. I purchased it years ago directly from Rick Kuehl as a 16.5" upper, and later had the barrel cut by BWE Firearms in Longwood, Fla., to about 10.5" and threaded 1/2 x 28. Comes with anti bounce weight, but not the ball detent modification.
I no longer have an M-16, so trying to clear out some space in the safe. Here are some photos. I am in Florida. Price is $650 shipped.
