I never had the issue with brass not ejecting or being interfered with on the couple T3Xs I’ve had using the 3-9 or 6X SWFA. If you did I agree that would be a big deal. It’s a non issue on my Barrett Fieldcraft with a 6X. I’m not a big fan of the 3-9 simply due to the eyepiece. Still have a couple 6Xs. I am absolutely looking forward to seeing how this turns out.
