Okay...That didn't show up for me when I did a search. I only found the food (ammo) finder group.Oklahoma Pew Pew. It is a private group and when you find the post just type RR in the comments. They will send you a PM with the details. The person is or was a member here. OH and he has interchanged some parts to make them look different.
