I have an idea, but I'm not very good w/3d drawing. What I'm looking to do is create a piece for the FX Impact- a new scope rail. I'd like to make one that has 20 MOA cant. The rear of the scope rail would be the same height as factory, and the front would be lowered, creating the 20 MOA cant. I would be able to send my scope rail to you for measuring and such. Any takers? I'd of course pay for services rendered.

I don't think a 3d printed scope rail is a good idea for several reasons, durability being the first. I certainly wouldn't want to put a scope I cared at all about on one. The mounting holes screw sizes are too small and I wouldn't trust the scope rings to stay tight. Plus with any temperature change your scope zero would change because plastic shrinks and expands with temperature at a different rate than aluminum. 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.

Buy a Taipan Veteran. ;) ;) ;)

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:

Valid points, but a few things I should mention (my fault, as I didn't specify in the OP)- I'm wanting to create a prototype piece from which an aluminum version could be made. Though, if the right material is chosen, I don't think durability would be an issue. I could potentially send the file off to a printing company to print it in a more durable material I have no access to, if the overall design works. Though, I'm not really sure that's an option as I'm not hardcore into 3D printing yet. I think you're picturing a straight copy of an Impact's scope rail, but with a cant in it. That's not the case- "my" version would be solid.
You're right- I could simply buy a 20 moa cant base and slap that on top of the factory rail, or I could purchase adjustable rings- but that doesn't solve one of my issues- overall height. I'm looking to get the scope lower. Simply adding a canted mount or rings would put the scope that much higher, defeating my main purpose of having a new rail made.

I saw your post! I'm keeping an eye on it for sure!
This whole post might be moot, as it looks like Kraford & Lypt are making an adjustable scope rail... Maybe I can convince them to make a lower non-adjustable rail w/a 20 moa cant... I'll send them an email.
-
I just sent an email to Kraford & Lypt with regard to my rail idea. I suggested a rail with these features:
- Half as tall as factory
- Non-adjustable
- 20 moa cant
- Either keep the two side rails, get rid of the side rails, or replace side rails w/M-lok or Keymod slots so if people want to run pic rails on one or both sides, they can.
I think the above rail w/M-lok slots would be a better option for most people.
Again, all this may be moot, since FX might already be working on a 20 moa canted base for the Impact, since the Maverick comes w/one. If that's the case, it may not be lower than current rails. I hope they'd be smart enough to at least keep the back of the rail's height the same as it is currently, and simply lower the front down to create the slope needed. That way, the rail would be a touch lower than current rails.
-
Kraford & Lypt is definitely NOT interested in making a non-adjustable scope rail... So I'll just keep an eye out for anyone wanting to help create a prototype for a new scope rail. I'm not too keen on K&L's adjustable version.
-
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.

That's true... But I'm sure that can be handled by the machine settings...
-
I'm going to put this idea on the backburner, until I get a 3d printer myself... I've been doing some looking into printing services and materials, and it's going to be expensive! That's even before getting the real version made. In the mean time, FX will probably come out w/a 20 MOA rail for the Impact. The Impact is their flagship- if the Maverick has a 20 MOA rail, one will surely be made available for the Impact. I won't be getting that K&L version, as I'm not a huge fan of the adjustability they're building into their rail. Thank you for everyone who offered to help!! I appreciate it!

Is it something like this you are trying to make?

What I have in my head is a complete replacement scope rail for the Impact that has a 20 moa cant and M-lok slots on the sides. Not a add-on rail.

Tom,
Perhaps you could talk Sabre Tactical into adding that to their line of FX Impact products. Can't hurt to ask: https://sabertacticalinc.com/pages/contact-us (https://sabertacticalinc.com/pages/contact-us)
Have you contacted FX or resellers reps to see if such an animal exists already?
serviceusa@fxairguns.com

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:

I did forget to get in touch with Saber Tactical ;)
One of the reasons I dropped the idea for now, is to see if FX would put a 20 MOA rail on the Impact/make a 20 MOA rail available as an accessory. There's one on the Maverick as standard, so it stands to reason the Impact- their flagship model- would get a 20 MOA rail as well. We'll see. In case you were wondering, the Maverick rail isn't interchangeable w/the Impact. At least, that's what I keep reading.
My idea replaces the side picatinny rails with M-lok slots so the end user can decide whether or not to run pic rails
The problem with going too low, is that the scope will end up lower than factory, and would require high rings, which negates installing a low rail. I changed my idea to keep the back of the rail factory height, and drop the front down to make the 20 MOA cant. But with such a small angle change (and looking at prices to have the piece made), I felt that right now, this isn't something that I can develop affordably.

I am surprised that they don't have one standard already.

Same- I would have thought they would at least roll out a 20 MOA Impact rail as an accessory when the Maverick debuted. When the Impact first came out, slugs were not really in the market eye- at least not at FX. Slugs have REALLY picked up steam in the relative short time since the Impact has been on the market. The community has really pushed the Impact in the last few years. It takes time for the parent company to catch up.
I sent Saber Tactical an email... We'll see what they say. It'll probably be "no", or "we're already developing something".

Hi,
im proficient in 3D design and own multiple 3D printers so I got experience working with them (and building them and other CNC machines)
So if you still want a 3D model and a stl file you can give anyone with 3D printer to produce for you contact me.
Regards,

There are composite materials that can 3d print and match the physical strength of the machined aluminum piece you tinkering about (only talking about that rail you asking above) but the cost will also match or may exceed just buying the original design from the shelfs.
I am not talking about print from filament forget about that technology, but laser fusion from powder.
The average cost printing that part you shall consider the ratio 33% is a material cost. One of the best services in US I can recommend https://www.shapeways.com (https://www.shapeways.com)
They can also print in metals like aluminum, stainless steel, brass
One of the materials I can recommend is MJF Plastic PA12 Glass Beads
-
I was looking at pricing from shapeways in those materials you listed, that's one of the reasons I stopped the project: cost. I'm not looking to produce these for sale. A single piece would have been VERY cost prohibitive, and the cost outlay for a minimum order would be even more cost prohibitive for me.
I'm hoping that FX will wise up and come out with a new rail with 20 moa cant for the Impact. It doesn't make sense to me that the Maverick has one, but their flagship model doesn't. Seems odd. At least offer it as an option.
The aftermarket rail from Kraford & Lypt isn't what I want, and I'm not sure if Saber Tactical is even working on a new rail. So for now, a 20 moa cant scope rail for the Impact is dead in the water.
