...I'd like to make one that has 20 MOA cant...
I don't think a 3d printed scope rail is a good idea for several reasons... You are better off buying a 20 moa scope base or a 20 moa rail riser which I think is essentially what you are trying to accomplish.
I just ran across some adjustable mounts yesterday. I did order a pair, but I haven't received them yet. I did ask if anyone had experience with these here:https://www.gatewaytoairguns.org/GTA/index.php?topic=183903.0
3D printing a rail strong enough isn't an issue. It can be printed from aluminum or even tool steel. The issue, as I see it, will be meeting the tolerances with the 3D printing process. A sloppy rail will be the weak link.
Is it something like this you are trying to make?https://sureshot-airguns.co.uk/product/20-moa-riser-rail/Dave
Tom,Perhaps you could talk Sabre Tactical into adding that to their line of FX Impact products.Have you contacted FX or resellers reps to see if such an animal exists already?Based on the Impact user manual and parts diagram (links below), the question is if you want to keep the integral side rails in the design; or keep thing simple/cheap and dispense with them? If you wanted super low Pic-Rail, then some of this rail stock below could be modified by milling a 20 MOA slope into it. Then drilling the mounting screw hole pattern perpendicular with the new bottom that mates with the rifle:
it stands to reason the Impact- their flagship model- would get a 20 MOA rail as well.
Quoteit stands to reason the Impact- their flagship model- would get a 20 MOA rail as well. I am surprised that they don't have one standard already.
