somebody.....anybody..... please help with some input on what are some of the best places/companies to get a mlock based handguard for my mp10. I also would like any recommendations on a scope also. I have always ran Nikon in the past but I am hearing a lot about this Vortex company, are they worth the money? or would I be better off sticking with a Nikon, burris , or something of that nature?
