Sounds like a lot of the comments are more concerned with weight (which you're not concerned about) than quality (which you are concerned about). I will say that I put a UTG quad rail on my 556 and have been pleased with it over about 500 rounds. Its not going to break, its aluminum. Also, it is a quad rail so its not smooth like the Magpul, but I work for a living so I don't have baby-soft hands like some people that are worried about it cutting them up. If you are, get some covers or wear gloves, easy fix. All told, I would just get the Magpul rails to mount if you already have the Magpul handguard; that would be cheaper and allow you to mount whatever you want. If you want a different look and don't want to break the bank, get the UTG. I've got a few other of their products as well and have no complaints. Its not like you're buying a car from them, its just a handguard, not any moving parts to break... its machined aluminum.
