Tang mount would be great if you can get it to work.
Possible. Would have to decide how I would do that. Im mostly focused on the guts right now, wo I can do a print to check function. Then I can spend time optimizing things for machining etc.I'd like to see an adjustable butstock on this. ARs are great because you can adjust it depending on if you're wearing heavy winter clothes or a summer T-shirt or chest protection.
I would be a little worried about strength there. For the gear I could buy some off the shelf gears and get them trimmed to the proper thickness. Ill take a look around amd see if there are any.Since the part is a one off and you already have the CAD file, would a shop that does 3-D metal printing be an option?
Unfortunately no. I had to move the fire control group back about 3 inches. I cant see a way to make a decent lever mechanism in a standard lower / upper combo. I know its been done, but thats beyond my ability. I am trying to use as many AR parts as possible though. With the latest iteration the BCG, Firing pin, Reciever, and probably the mag will be my design. Only changing the mag release for ergonomics. Since I moved the fire control group so far back. The amazing thing is the internal volume is still is about the same size as an AR lower (to the entry of the buffer tube).Sweet! Does this mean you might go to a upper and lower receiver with pins?
I've got a few cough cough* Marlins. My 39A is the smoothest and best shooting 22lr I have. Too bad they don't make them any more. I've seen them selling for $4k for the octagon barrel version.I was thinking a unique upper half and lower half of your design. My Marlin 39 splits into two halves but they are left and right.
If you go with non-captive take down pins, have holes in the stock so you can stick the pins in there while it’s taken apart. That way they are less likely to get dropped and go rolling away.Here is a cut away view. I'm working on details now such as how its going to be assembled, if the take down pins are going to be capitve (probably not), then moving on to the stock. I think the hardest part to get machined will be the BCG, since the gear teeth have to be cut into the bottom of it.
