Picked up a new FX verminator this morning. I had to wait until this afternoon to try it out, Very nice so far, scope zero'd,good groups with AA field.
After i had finished shooting I grabbed my trusty oily rag and started wiping the barrel, This was when i noticed the marks were rust spots and not just one patch.

I don't think it's unreasonable to ring the shop tomorrow and ask to swop for a non rusty one?

My 7 year old AA410 i traded in had less marks on it!
