I'll just put it bluntly. I want to turn this CA M16A4:
Into this M16:
And I'm willing to spend what's needed to make it possible.
Now, as said above, this is a Classic Army, and I've heard some modifications won't fit.
My primary concern is getting the heatsheild to work, how I'm going to actually get it on there, what I have to buy to make this work, where I'm going to buy it at, and how I'm going to get it knowing some items cannot be purchased at will.
Help is greatly appreciated.
