Ok, that's what I thought. You have a c-tool bolt. I take it you didn't get a c-tool with it. Contact knight as they should be able toget you one.

But that doesn't solve your problem now. If you have wrenches take a 7/16 wrench and place it between the secondary safety like the picture below.



Then screw the safety being very carefull that the wrench doesn't come out. Screw it out till you can get your bolt back into alignment.Then you can do it again to dissasemble the bolt.It'll take a thinner 7/16 wrench to pull this off. Mine is about 1/8" thick and it is just barely thin enough.

I've lost a c-tool before and needed to come up with a temporary fix. Try this and let me know if you need further help.
