[Skywalker]

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.
