Point taken...

but the problem is that the gas ports might be in different locations, or might be of different dimensions. You see, the amount of gas going back is crucial--just enough to cycle the weapon, not too much, which would break buffer tube and buttstock eventually, and not too little, which would not cycle the firearm.

Also, you might note that while the Canadian C7 is a bit different in the stock, the C7 is a piston driven rifle, not a direct gas impingement system like ours are.

The picture on the AR15 site shows a stock with the same buffer tube dimensions as the standard stock.
