Yes there are and knives too but that doesn't mean they are not allowed. Unless someone complains they don't get pulled. Check their TOS before you tell anyone they are wrong.
No offense but you may wish to do the same. Their policy is plainly visible here:

Barrels and mags are allowed with some caveats (basically US sales only - mags must be 10 rounds or less and shotgun/rifle barrels must meet federal minimum lengths).
For the most part except for frames you can sell most firearms parts on ebay just fine.
Most knives are fine to list too.
