Bore guide for Tavor? Something long enough with a solvent port in back? One of the metal ones instead of delrin?

I expect I'll try different bore guides made for the AR/MSR but it needs to be little longer than most with a solvent port in back - don't want chemicals loose inside the polymer and I don't think the ejection port locks or ports quite match - works nice for an AR locked open but the Tavor doesn't lock open so... again maybe some do?
