I've been working super hard on this chassis for some time, over a month I think. I finally got it to a point to where I think it done. It is the most complicated thing I have designed to date and I'm really excited with how its turned out. The gun is a 357 AEA sidelever Challenger, a beast of a gun. This chassis takes just over a pound out of it as compared to the factory wood one. It was a ton of work getting it to this point. I also printed this on a new custom printer I made, and getting that right was another endeavor. 😮‍💨

Excellent job looks cool. That's not a small task

I have a .30 bullpup would this work or could you share stk so I could modify it to work or maybe help you modify this one and purchase one?

This would not work at all for the non-side lever guns. Those are vastly different and have changes that depend on the year the gun was made. I know, at the least, early non-sidelever bullpups have different tube sizes.
I will not share any of my STL's or cad files. I takes a lot of work to design these and that is what I am selling.

I think the tube diameter is different. This is a problem since the dimensions for everything are based on the tube. The side levers have a 41mm tube. Like i said previously, they used two different sized air tubes depending on the year for the standard bullpups; with the earlier ones having a smaller diameter tube. Please measure yours to see what the size is. The volume of the tube is very different for the side levers vs the standard guns. The standard guns have a 300cc tube and the sidelever's get a 500cc one.

I have the .457 Challenger Big Bore Rifle and it's a beast to lug around in the woods. Do you have any plans to try for a lighter stock to fit the rifle versions in the future? And if you printed that larger section in one piece you must have built an awesome 3D printer, which in itself would be a huge task to design and get tuned. Congrats sir :)

Thx
Ray
