I always thought the top would have a single picatinny rail bolted on, or molded in. Then one could use a riser, or rings.

I already have this red dot sight, so I'd probably use it...

There is also a Leapers scope mount that has 30mm rings, plus top and side rails. So one could 4X scope it, have a compact red top on top, and side laser and flash light!!!
I would assume I would Armacoat it, but having Mystic do it in bulk would probably be more economic.
One could make a new barrel given that it is fixed. Barry at could do it, I wager...

There are only 9 or so interested so let's see what you are all expecting.
You need to start a thread on it in Black and Green rifles.
The buttstock mag holders could either be done by you or parts supplied and I install for free when the stock is purchased. Will have more details once I figure out how it will actually work.
Yes. Having a half dozen extra mags on the carbine is essential. I would actually like to see the stock space taken up with a hopper style feeding system
for the mags. Take a mag, and the rest pop forward, or rearward, or whatever.
