I don't really care who developed it as far as Im concerned they left the job unfinished . damn near 70 years an they still cant mount a optic on it correctly .
I have sat an stated at how I could make the AK parts look like An american rifle by putting a charge bar on the side or bottom to get the piston over the barrel gone . It would be pretty easy to move this an that an call the design your own . I have a cut up carrier for just such a project some day.
Im sure I could take a m1 an move the stuff around an get a AK looking rifle .
I have never understood the reason fore the short site radius an the heavy an complicated to make RSB when a GALIL type gas tube setup would have taken more than a few ounces off weight an cost a lot less to make an made the gum easier to shoot accurately. needed no latches to hang up on stuff etc.
maybe all the vodka made it so they could not focus on a rear sight that close to there face ??
