Hey all, i'm a little new to the AR platform style rifles, and i'm running into a potential issue. So, i'm waiting on a scope to arrive for my AR and realized that there's a potential of my front sight being in the way once the scope is installed. I really would rather take off the front sight altogether, but i know part of the gas block is located there as well. I had future plance to change out the stock handguard as well, so i could put a forward handle there. Anyhow, how big of a deal is this to change it out so that there's nothing in the line of the scope? Any suggestion on what brand parts to replace it with? videos or instructions on line anywhere? My rifle, is the Rock River Arms tactical entry model. The scope i ordered is the Nikon p223, which is on backorder everywhere i've looked.......Thanks in advance guys. Cheers, hvychev77
