overall decent AR, the problem is the Troy Quadrail.
The Troy quadrail that comes with this model rotates several degrees left and right and there is no way correct that. I took mine to several armorers who were unable to fix it, I showed to several S&W reps. they all said to send it back to S&W for repair which I did. It was returned with a repair ticket and there was no change, the quadrail still is loose and rotates. I have a grip-pod on the quad rail among other accessories and the weapon rotates in the quad rail, not what I want and S&W could care less about fixing it. Don't tell me that there are tension screws that will fix this because there is not. I Paid ~$1,200 for this AR and had higher expectations for quality that what I am stuck with. I now need to pay ~$300 to $400 for a decent quad rail that will perform like it should.
I may not spend any more of my firearm money on S&W as a result. BTW I have 26 firearms and am only just starting my collection.
