Hmm, from my understanding of chassis, ability to accept different grips, butt stocks and forend attachments makes me wonder, could you make the forend interchangeable? That would then focus smaller blanks to the action interface, trigger, mag feeding which seems to be action type dependent...A buddy that builds/sells aluminum chassis said his cost for aluminum blanks went up a minimum of $200 per chassis, more on larger/longer ones.
Gonna be hard to reinvent the wheel and keep costs in line.

ARS (Accurate Rifle Systems) makes a few variations for the different Savage actions. To Adam, the original poster, I'd like to see your new design. I think you'll find so many different disciplines have their own idea of what is "best". Hard to keep everyone happy and still be able to keep machining costs down with a multitude of options.Dont forget Savage actions! There are a lot of us that love them but have a hard time finding really nice Chassis because no one wants to make them.

The need to mount the scope to the barrel for improved accuracy is news to me, can you provide sources of that info? I ask because I'm surprised I have never seen the BR accuracy community bring this up as a topic, and I would suspect a standard action mounted scope rail would save substantially on the cost.I did end up having a proof of concept manufactured. The design idea is to have a scope mount integral to a barrel block clamp. Some research shows that the scope moves in relation to the barrel shot to shot. This can cause degraded accuracy and fliers. There is possible movement between the barrel and the action, the action and the rail, and the rail and the rings. This chassis bypasses all of those. The POC is not pretty, but proves out the design. I had a shop build a barrel block top, and an insert that was epoxied into a rough cut wood stock. The testing I did shows that the average 5 shot group is reduced a small amount (from .55” to .5” in the rifle I tested), but had a noticeable reduction in the combined 20 shot group, going from .925” to .7”. Further testing is needed to confirm these figures are repeatable and statistically significant, but the design appears to actually improve accuracy.
Unfortunately the cost of R&D and manufacturing prototypes ended up being significantly higher than planned, so this project is on hold for the time being.
Here it is a rendering of the chassis for a long action with cip magazine:

And here is the proof of concept glued into a wood stock. It is ugly, but it works:

The forend has a full length arca rail for the PRS shooters, which would accommodate the grayops plate. I also kept the barrel close to the forend, I think it was 1.25" from the bore centerline to the bottom of the forend.If I can make a suggestion if you are catering toward the prs crowd. Have a place for a grayops plate then have the BA as low to the CG of the stock as possible
