thanks for the interest everyone.
back section of barrel done. i had a hole arrangement issue i didnt notice till after i cut all the holes. i didnt want to reprint and cut, cut,cut so i just plugged the holes that needed it for the sake of this build and fixed the part sheet. 1st pic you can see the holes i plugged. second pic with some digital editing shows what it should look like.
@vbsargent- hadnt thought of that. that might work. and if im not mistaken is there not allready a Sturmgewehr 44 available about the net?
now me thinks i start the difficult parts....
