I just purchased the TS model today. On S&W website it states a Troy trx extreme rail but the one I have has a Troy Alpha rail with the 3 set screws to hold the rail in place. Did they change specs or just a fluke on mine. Got a good deal $1169. I put on an Eotech and an AFG 2. Good looking AR Gonna shoot it in a couple days. Any one else have this model any pros cons Thanks ShooterJD
