just got a m&p 10 yesterday and i am really wanting a quad rail. i hate the magpul quadrails so none of that. im not looking to free float just simple drop in rails that require minimal work. (under 125 please)
Look at Damage Industries (damageusa.com). They have one for $89.95. Its a tight fit but it dropped right in no problems. 4 screws to hold it tight and done deal. I have now added a centerpoint laser/light combo(found at walmart $49.95) a centerpoint 4-16x50mm scope and a fore grip/ bi-pod.This was recommended to me by another member of this forum. Its sighted in and looking sweet. Ill try to post pics asap
