In terms of quality they rank in this order:

• Delta Force 2 (just solid action and story from start to finish with great pacing)

• Invasion USA (this movie is kind of silly but also pure badass, probably Chuck's most badass role, he just gives zero effs taking out the bad guys in this one and that final massive battle sequence in the city streets of Miami is the sort of thing you never see in newer films)

• Missing In Action 3 (Basically Chuck's version of Rambo 3, but I really enjoyed this movie. Lots of balls to the wall action in this one basically from start to finish)

• Delta Force 1 (Chuck teams up with Lee Marvin and they clean house with a squad of badasses. It's kind of goofy and a little bit like Megaforce, but plenty of action and very patriotic, somewhat like the Expendables before the Expendables)

• Lone Wolf McQuade (Chuck vs David Carradine is the highlight, plus that Ramcharger is a beast)

• Missing In Action 1 (An iconic film, but it doesn't really get going until near the end. This is the movie so many other movies copied off of when Chuck comes out of the water with the M60 and blasts the ever living daylights out of the bad guys)

• Silent Rage (I really liked this film because it's a horror film but it stars Chuck Norris. Way different from his other stuff, and even though Chuck didn't like it, I thought it was cool seeing him face down against what was essentially a low-rent Michael Myers)

• Firewalker (A poor man's Indiana Jones, but I'm a huge sucker for travelling adventure films, and with some martial arts fight sequences? Just my cup of tea)

• Good Guys Wear Black (it's an interesting film with a few twists and turns, it's not fantastic but it's a good enough watch)

• Sidekicks (This is a good one for the family)

• The Hitman (Another interesting film where Chuck plays against type throughout most of the film. The sawed off shotgun and duster were the real highlight here)

• The Octagon (My old man loved this film, and it's interesting for what it is -- the fight with the Black Star Ninja might be worth it. Your mileage may vary)

• The Way of the Dragon (as others noted, this was the one with the iconic fight with Bruce Lee, but it's not really a Chuck Norris film)
