Would love to see how it turns out. I am waiting on a couple stamps for SBRs, this would be an awesome addition!

There is a small machine shop in the Joppatowne area (distance from you) who I used to work with at a previous job. I've seen gun barrels in there before, he did some kind of modifications to them for APG. Point is he's at least somewhat versed in working on firearm components.
If you got a design down this is ripe for a patent.
Unless its materially different, there is already prior art. Past the one year deadline now. (I have four(?) patents and a coupe more pending so have some experience in this.)

So you're saying because there is already a picture online showing that someone built one there are no longer grounds to file for a patent? I'm not too familiar with the patent process.

I'm not sure how his mounts and locks in place so if I were to patent anything in hopes of production, which I'm not sure I have the time for, I can't for fact say what I'm doing is what the other person has or did do.

Is this the part you would need to be donated?

Well more so just needed the part with all of the hardware to do some measurements. Figured someone might have had a parts kit for an AK sitting around and would be able to loan the stock for measurements. If I can't find one local by Thursday, I'll just order that to see what width I'd have to go with and how much clearance I'd need in the wrist area.
I think I'm going to go through and prototype with a 3D printer first and see what I can get.

I was actually on planning on ordering something from Sportsmans Guide. If it would help to move the project along, I wouldn't mind ordering the party. PM me if your interested.
Yes. 'Prior art' is some sort of public docmentation of the idea that has existed before yours. In general, when you have a patentable idea you can discuss it in private w/ clients but once it hits public knowledge you only have a year to file the patent. That fellow on the 300blk forum couldn't file for one now as an example. Too late. So you have to have an even BETTER idea that is considerably different and 'not an obvious extension or combination' of other ideas or prior patents then you can apply for a new one. They have gotten much harder to get recently.
Edit: All that said, lots of patents get approved for stuff that already exists. The patent office can't find everything when they search. But in a court case, someone just has to show the prior art and it will be invalidated.

Per some research it seems that the different location (Russian, Yugo, and Polish so far) have slightly different hardware on them. Going to find some shops out of state that have underfolders in house to check out the hardware as best I can.
I've got several side folders if that's of any benefit.

Of course, to make this really work, you're still going to need a stubby receiver extension and modified buffer, new springs, etc.

No need for a new BCG with this one http://www.quanticotactical.com/asp...emNum=5594&type=C&subCatNum=52&CMN=Buttstocks Buffer and spring is included if you get the captured spring set.
