I'd like picture of the gun/internals. Did they just remove the disconnector and not install a SAO trigger? With that much pretravel, maybe they just pulled the disconnector out?
Depending on what you want to do with this RAMI, a pro package is the premium solution. As mentioned, you just need a disconnector (and maybe a trigger) to make it DA/SA again. There are other nice to have parts in the pro package but it depends on what your after.
SAO conversions/actions aren't generally legal in most divisions in USPSA. You have certain divisions that you can start locked and cocked but the RAMI would not be competitive in them (at least not in my hands:)).
Cheers,
