sci-fi anti tank rifle

this is learning project for myself and was made to fill a spot in a costume. based it on a ptrd-41 rifle, mg42 and a g3 scaled up for star-wars use. this is not yet tested but it should assemble and cycle the action taking with it the shell that comes with it. the barrel for this is any 3' pvc pipe you can get at the hardware store. have yet to figure out an extractor for it so I put a hole in the tip of the bolt for a magnet in the future. (note the scope and bipod I have for this project are metal, i do plan on uploading printable replacements)
Update: it prints well on my ender 5 plus, the bipod bracket and scope are found parts and i will later come up with a printable scope.
