Speaking of Butler Creek covers....

Does anyone know the correct BC cover to order for the ocular lens end of a TA-11 ACOG?

Sorry, I don't.

I would just take the scope (if you have it) to Sportsman's Warehouse or similar store to size it. The sizing charts online can be rather unreliable.

For example. the covers for my Leupold VX III were a totally different size that what the charts said.
