Not a direct fit for s&w m&p 10... - Sniper AR .308 Quad Rail Handguards w/Round End

This is NOT a direct replacement on a Smith & Wesson M&P 10. It will fit if you turn/machine/file 0.08" off the delta ring end of the guards. It's not hard to do and it fits fine after you hand fit it. You get what you pay for... At the cheap price, and adding in a couple of minutes on the lathe, it was worth it for me but I would NOT recommend it for a guy looking to just snap in a new set of hand guards.
