Also, if you really want to make an exact copy, you'll need all kinds of useless and expensive parts such as: an ambi charging handle (which is crap, breaks easily and is a pain to use); a rear receiver plate with sling loops (also crap, because the loops are too high), an ambi fire control selector; and an ambi mag release (more crap, since it lets your mag drop when you're marching or slinging or just looking at it the wrong way). Last and not least is the Tri-ad mount, which is more crap. If you can't find one, just tape a brick to your front sight post. Speaking of the front sight post, C7s use a round 0.050" post. You know, come to think of it, the only good part about the A2 is the telescoping butt. Even then, it sucks because it's a 4 position and not a 6 position. Also, toss in an Otis grip kit but without the cleaning kit.

Oh right, I forgot the accu-wedge.

If you're really after replicating a C7A2, buy an accu-wedge aand when nobody's looking, huck the damned thing into the woods......
