Nerf SlingFire short dart conversion

These are supposed to be fully printed, drop in replacement parts for the nerf slingfire. Although I modelled these from scratch to match the slingfire's dimensions, they were heavily inspired on SomeDingus's Nerf Retaliator Brass Barrel Short Dart Conversion and on BanBot2's Extended Knockout Short Dart Barrel Mod.The bolt replaces the original bolt (who would've guessed!) and the barrel replaces the dart gate thing. The only extra hardware that is required is another 9,25x1,78mm o ring for the breech seal.If your machine is well calibrated they should be pretty simple to install. Mine was a bit off, so I needed to do quite a bit of sanding to make the breech seal nicely.I'm getting ~85fps on cut down accufakes. That's with a grey trigger spring and a 10mm spacer.You are also gonna need a short dart magazine adapter to use this kit.If you have any problems installing this, please let me know in the comments.
