Inletting that stock was nerve racking with only 1/4" wood walls on either side of the trigger group. We're also treating this as a "prototype" for future designs, so being able to adjust parts simply will help refine the design over time. I would like to make a completely internal design as well sometime soon.
Yeah, there's not a whole lot of room for error while you're inletting the stock.
Keep up the good work man!
