Default need blueprints for scar 16/17 reciver

ok so this project is still floating in my head. i made a post before
http://www.calguns.net/calgunforum/s...d.php?t=650491
but didnt really see any interest in it but i want to still do this project for myself and maybe if there's more interest after my final 80% is complete.
and yes i understand that the cost of this will be way more then to buy an off the shelf scar but i enjoy the bulid and milling of my own firearms. there no fun in going to 80% build party and pressing start on a cnc. so if anyone has any blueprints from fn (that might be almost impossible to find) or detail mesurments for a scar 16/17 both and both left hand and right hand charging handle. thickness , length , slots, holes, thread hole and size pitch i mean everything. it would be greatly appreciated. ps even a pat number will be nice i think pat. plans are public info.

I think that's probably something you're going to have to figure out on your own. Reverse-engineering a set of blueprints probably takes a long time (seeing as I've never tried before), and there's probably no possible way you're going to find someone to do it for free.

reverse-engineering was plan z lol. there only one company i know that sells stripped reciver ffl (desert dogs)... they some time pop up on gun broker too might have to go that route if cant find any prints.. i hear you on the free part, how about a case of beer

Utility patents don't include much in the way of measurements and where they exist they're generally ranges in dependent claims "one embodiment of claim 3, with width between 1.2 and 1.5 inches".

Design patents are just what something looks like and don't need measurements.

This is exactly the type of project that I am looking for. I have an engineer who is just as motivated as I am to work on a project like this. I will tell you what if we can get enough people to get involved I will reverse-engineer it and build it. What are your thoughts?

How about a link to your website. We'd love to see what your engineer has done so far.

Step 1. Buy a upper
Step 2. Take upper to a machine shop with a CMM (coordinate measuring machine)
Step 3. Pay machine shop 80+ dollars an hour to measure upper.
Step 4. Pay machine shop to program upper, ball park of 2000 dollars.
Step 5. Pay machine shop to do a run of parts.

Subtract expenses you can do on your own.

The website is diyarms.com. We are in the process of finishing up on the design for an ar15 and ar10 80% lower project. I don’t have any cad drawing due to the fact that we keep changing our minds on the design, but we should have something popping out of the machine in the next couple of weeks.

What I was getting at is I have a shop with a CMM and I am very interested in this project. I am not going to buy a scar, so what I was hoping for is to find someone local who has one and we could meet up and go from there. The shop is located in Anaheim CA

That is the goal… My programmer told me that if he could hold it in his hand he can create the 3d model.

a 3d model with measurements would be great DIY Arms !!!.... but as far know i dont think you can cnc the upper receiver, i believe the upper receiver is extruded and i have a friend that will make the die for the extrusion company if he had the plans or blueprints . so bollero i dont think your haas will work since it is a cnc. the lower reciver does not carry the s/n the upper is consider the firearm and that is what carrys the S/N and that would have to be the 80% part to make.... here is a lower you can buy no ffl since it is not the firearm http://www.rainierarms.com/?page=sho...roduct_id=3217

I would be willing to buy a bare upper when I have the cash in a few weeks for someone to use for whatever if they can make an 80% version...

I would be wanting 5 if people want to do a group buy.

id ultimately ditch the serialized upper once the project is done

^ I'm with you, if it ever comes true seems to be the key. How will the 80% work here? What will be left out? It's not your normal 80 where you leave out the FCG pocket or external rails etc. seems like it would be a pita to get ATF to declare a non gun and finish on your own.

well it is to elary to say what would need to be finish but by looking at drawing i would say charging handle slot, ejection slot, rear and front reciver plate holes and maybe a couple other hole that are drilled into the upper but that is just a guess right now . as far as sending it to atf not really a pita more time consuming if anything but once the atf declares it as not a firearm it will be good to go

i think to start we should take a vote to focus on either a scar 16 or 17. eventually if the first product goes as plan there shouldn't be a problem with the seconded product.... so everyone that is interested to post a vote (pick only one "scar 16" like this").... again this is in the early stages, so it could be a bust or a success...... i am going to start emailing company's that sell scar hard parts and see how difficult parts are for them to get and if they would be able to set up parts kit...

Scar 17!! 7.62 ftw!!

hi-desertdog.com sells a lot of Scar 16/17 parts. they even have parts kits.
www.midwestgunworks.com also sells SCAR parts

I think it would be wise to go Scar 17...
Also, lowers seem to be easier to get a hold of for the Scar 17...
My plan is to build off of a Handl Defense SCAR25 Lower which is designed to accept AR/M16 type grips and can also accept aftermarket mags SR25, M110, Pmag20

Either way, I'm going to start building a Lower and accumulate parts!!

if you can barrow a receiver and have access to soildworks you should be able to make your own blueprint

barrels are going to be expensive as crap not to mention parts availability is going to be shotty at best. barrel extensions are 190 a piece and i havent seen any gasblocks floating around for sale. i have an 18in stripped DMR barrel thats STILL waiting for the rest of the parts to be able to drop in...

It look like we have a lot of people with the skill and resources to do this, but we are missing the most important part, a guy with SCAR 17 in the local area to take measurement from.

If money is an issue, get a few people to chip in to get one and those people that chipped in can get money back from whomever is keeping the receiver in the end.
