Dem people you were absolutely right. My cellphone actually got through to Colorado guns and spoke to a tech guy. I do have to have the original Sig front to go along with the rear, glad you brought that up.
I have ordered the front and the rear should get to them in about 15 days and will get it shipped out.
I have been told by the tech guy that I will have to make one mod to install the rear sight. When I remove the rail there will be a nipple sticking up where the screws go into the receiver. I will need to remove the verymost rear nipple to install the sight. It does not have to completly go away so there will be enough to reattach the original rail.
The rear sight will also have a sling attachment and sit level with the receiver which will make mounting optics a non issue which to me makes it worth the price.
Does anyone on here use this setup or am I the tester? I will either have it done by someone so it will be ready when I get home or do it when I come home. Either way will get it all set up and take plenty of pics.
