3rd Gen RAH models:
A little over a year after losing the hard drive with all of my STLs I've finally recreated full part files for both my Pump-action and Bolt-action variants, along with a number of improvements. By mounting the handles externally rather than internally, I can remove the handle easily for maintenance or I can use a traditional PVC bushing, which would have been very difficult with the previous design. I've also made a number of smaller adjustments, going to 4 mounting screws from 2 for additional stability, shortening the trigger for a more comfortable pull, and using a number of lessons from the previous models to build in tolerances to make everything run more smoothly. The Pump-action variant is currently borrowing a slide from an older version until I get a hold of some more 1 1/2" thinwall.
