I got a UTG free float for free from a friend. He bought it from cheaper than dirt but upgraded to a YHM free float. He said he got it from Bravo Company for $100.00
I agree on the Troy rails. The VTAC rail is also pretty well priced. I personally love Daniel Defense rails and midwayusa.com had the Omega X FSP rail for $200. The rail was worth every penny...
I got mine from Optic Planet for an M&P 15 OR.
It is from Osprey and cost $45.00 plus shipping.
Very clean and very well made. Very pleasantly surprised.
The material and quality are top notch compared to ones that are twice as much.
