S&W M&P 15 AR-15 16" barrel - $550 - Westford, MA
Great rifle with S&W M&P 15 lower and a Palmetto State Armory upper.
I have a few hundred rounds down the pipe at most on this combo.
It is a standard LPK, but I stoned the sear surfaces and installed a JP Enterprises spring kit.
It has a very consistent 4 pound trigger pull.
The upper has a 1/7 twist chrome lined barrel and a Miculek brake.
The upper is a flat top style and includes a clamp on carry handle.
I am also throwing in a 30 round preban refurbished magazine.
