This year Smith & Wesson have launched the M&P15 PS and PSX piston operated AR-15 rifles.


M&P15 PSX

The only difference between the PSX and PS is that the PSX features a Troy 7″ modular quad rail handguard.

    Are the S&W M&P 15 PS Handguards interchangeable with other handguards? I'm looking to put on a quad-rail. Any suggestions?

    I have a set of the factory PSX quad rails (made by Troy, marked Smith & Wesson M&P) that are a drop in install on your PS that I don't use anymore. If you're interested, shoot me an email (basshead87@aol.com) and I'll shoot you a price. FYI--S&W is charging $140 for them!

      @Mike Mike, I would like the PSX quad rails (made by Troy, marked Smith & Wesson M&P) that are a drop in install on your PS. Please give me an idea of price wanted.
