Here we are trying to come up with a solution for connecting a quick disconnect attachment for a sling towards the back of the gun. There were a few other designs but this is the most current one.
After designing in CAD, we prototype with a 3D printer. This really helps us prototype fast and cost effectively. If there is a change that needs to be made, we'll redesign in CAD and reprint until perfect.
So far this design is working great and we'll be moving forward on machining it.
Next update will have the machined part. Note that the machining and anodizing processes can take some time. From designing to a finished product it's about 4 to 6 weeks.
