I know the box says it's a 6920 but how do I know the gun is? I don't see those numbers on the gun.

Just go to Colt's website and matchup what you've got.

Really typically the only difference between the AR6721 (HBAR) AR6720 (Pencil Barrel) and LE6920 (M4 profile barrel)is the profile of the barrel.

Other models have differences like railed handguards, piston etc.

The receiver markings have very little to do with the actual model in many cases. With Colt LE models, many things are exactly the same with a few defining differences. But it doesn't matter, the QC is there.
