I am currently working on my first build and have the lower done so now I am hunting for an upper. Almost everywhere is out of stock of everything.
I did find this one still in stock on CheaperThanDirt.com. http://www.cheaperthandirt.com/product/ ... rce=search
First off is this a good lower? Second. I'm not sure if I will like the 9" hand guard. I was thinking about wanting an 11" or so. How easy would it be to replace the 9" with a longer one if I wanted to? Since it's a free-float hand guard does that make it easier to replace with a longer free float hand guard? Do I have to mess with the gas block, etc?
