Dude, no joke, i have absolutely no idea how that happened. ALL the reference pictures i've seen have the charging handle on the right, the MODEL that i used has it on the right, but somehow it ended up on the left. I noticed it once the rifle was fully assembled, and i thought i was going insane. I had to go back and check everything. the chunk of rifle that its attached to isn't symmetrical either, so it couldn't have been me gluing it in backwards! i have no idea how it ended up on the left. One of life's great mysteries i suppose.
