Just for future reference, the only difference between the M203A2 and the original M203 (at least in the US military) is the type of clamp used to secure it to the barrel.
This is the original clamp used when the 203 was adopted in the 70s.
The A1 and A2 models use the Knight's Armament QD clamp seen here.
And on a side note, we could use a pic of a Canadian M203A1 for the site since at least 1 movie we have on here (Universal Soldier: The Return) uses it instead of the American version.
