i was looking for something different to try with a new, upcoming ar15 build and ive been looking at some of these monolithic uppers and ive been wondering what their purpose is... surely there has to be some advantage to them besides a full length top rail as i recall seeing forearms that were actually held on to the rifle by mounting to the A3 top rail giving a full length rail...
so is there some other reason these exist? do they provide a lighter rifle, or typically a heavier one since theyre made of aluminum, are rifles made with these stronger, more rigid, or in the end is it all really just a gimmick?
