So I am about to purchase an sp89-mp5k and I was wondering if anyone in AZ would be willing to go out and shoot in the desert with their auto sear.
Well, if you were in Indiana, no problem... though after this winter, maybe I should consider a move.
Just make sure your SP89 has been updated with a full auto bolt and the proper locking piece (and you have an MP5K trigger housing that will work for an SEF or whatever pack the donor is bringing). Nothing worse than getting out to the range, only to find out that you don't have the right parts.
