    Default Diamondback DB7 Still Issues with Alignment for ZERO MBUS and VORTEX SFII

    New post but old problem on still new gun. First, link from initial find on the alignment issue from when I bought the gun new and posted on here.

    After alignment on top rail was correct I had not went back to the range till past Monday with a co-witnessed Vortex Strikefire II and my MBUS. This gun is still new and never hit paper as of yet. I should of laser bore sighted Monday before going to Magnum but I didn't as I thought I would hit 10 yards and walk it out. No go.. no paper at all from red dot or MBUS. So, here I am again now that I'm focused back on this weapon and the issue here.

    After my attempt to hit paper at Magnum Monday I came home and did what I should of in the first place. Laser Bored Sighted both VORTEX and MBUS. I can't live with that MBUS that far off as its not normal at all. So, I coordinated with a secretary at Diamondback yesterday and this morning as I was wanting or trying to talk with a smith. She seems to be stalled with what type of ammo I am using and such. But maybe they will eventually help.

    Here are my photo's and I ask for your thoughts on this... First two pictures are original from COAR15 Forum years ago. Last photo is current now that I have bore sighted VORTEX and MBUS. Zero I'm sure but not acceptable. I'll never be happy with the MBUS this far off center and I did swap the rear MBUS out but didn't help.
    So, "COLLET" ? maybe?
    Thoughts please.
