Here's a couple more pics, I've made an initial finishing pass. Still some work to do yet.
I've forgotten the proper size for the mystery disc, is this too big?
I need to decide on my method for mating the upper and lower. I may have to draw something up, since I've filled in the screw hole under the barrel, and the holes for the pins, though since the upper has been moved, they wouldn't work anyway.
I'd like this to be a mechanical connection, and relatively easy to take back apart if need be. I may model something that'll go inside the magazine well, grab onto the 1/4-20 rod for the scope bracket, and then somehow attach to the upper. Just need to picture it in my head.
