Aside from the happy switch vs. really happy switch, the sights, and the handguards, are there any differences between the M16A1 and M16A2?

Barrel profile and twist rate. Stock and pistol grip too.

Barrel diameter, twist rate, flash suppressor, grip, stock, handguards, front and rear sights, fire control group, delta ring, lower receiver shape, ejection port door, forward assist button, case deflector hump, and probably more.
