Tyranid biomorph ability question

[H.P.Munchcraft]

So the biomorph ability says you can attach a one-shot to the card for a permanent combat bonus. What about the other effects one-shots give? Could I use this ability with the more Dakka card which increases the combat bonus of hand items but doesn’t actually have a combat bonus itself?

If the One-Shot doesn't have a combat bonus of its own, it can't be attached to a Tyranid.

That seems inconsistent with this ruling, or is there something I'm not seeing?

The more recent rule is correct. My earlier ruling was in error.
