Complain away to me.
I'm all ears.
Be very careful if this is a personality issue. If you can't get on with your muckers, it reflects as badly on you as on them.
Depending on the issue, if I was your OC, I would want to see evidence that you had tried to resolve the matter yourself before coming running to me - I have SNCOs to solve problems, not cause them. If it is impossible to do it face to face, then speak informally to ASM in first instance, as he/she would almost certainly prefer that it was resolved within the mess as it reflects badly on the ASM if his/her SNCOs are bickering without any action being taken. Were I your OC, my immediate next conversation after speaking to you would be with the ASM anyway in order to get the low down, so you might as well get top cover.
