Any news on the S&W Piston AR?

[Beat Trash]

Title says it all. I was on the S&W web sight and they list a M&P15PS and a M&P15PSX.

One is a piston rifle, the other is a piston rifle with Troy hand guards.

Did anyone attending the SHOT show see a prototype of their Pistol Rifle?

Pistol rifle? Mean piston rifle? It's their normal rifle with an Adams conversion.
