So this was my first mod. my little brother got a used longshot with a broken front gun and i decided to cannibalize it rather than trying to fix it. AR removed and a rose art window paint marker in the longer barrel out of the front gun. I shaved down the breach and added a neoprene oring. Then I glued the front guns coupler to an old nerf blowgun I had laying around to make a removable barrel. I'm almost done with my high cap magazine.
