Tippmann 98 to AR Buttstock Adapter

thingiverse

I was rebuilding my Tippmann 98 and thought, "Man, I wish this thing had a buttstock!" My buddy who helped me build my Proxxon Vise Adapter and AR lower milling jig owed me a favor or two, and he happened to have an extra AR style buttstock sitting on his shelf. After a couple of hours of tinkering and a few prototypes later, I came up with this adapter that lets you screw a standard AR buttstock into the back of a Tippmann 98 paintball gun. I made two styles - one with a "tail" (I have no idea what it's called) used with the locking plate to keep the buttstock upright, and one without. If you use the tailed version, it will interfere with the gun's grip, but I already designed it, so I'm including it anyway. With the un-tailed version, you can tighten down the retaining nut on the buttstock enough to keep it upright for paintball games (it only feels like war). Keep in mind that with the buttstock screwed in, this adapter will take a lot of torque, so print it hot (to promote layer adhesion), slow, and at high resolution. Print with supports. I did make the tolerances on these pretty tight since slop or play may affect the marker's operation. During post-print cleanup, just heat up the rings that go into the back of the marker (you need to take the marker apart to use this) and spin the adapter in the grooves to make a tight fit. There is a tab on the adapter that should keep it from spinning, so be careful to align it correctly at the top, and don't flatten it when heat-fitting. I also used a little bit of Teflon tape on the buffer tube threads just to tighten things up as much as possible. Sorry for the sloppy prints in the pictures - my tip is worn out and I'm waiting for my new one now. But these still work just fine. Print Settings: Printer Brand: Printrbot Printer: Printrbot Simple Metal Rafts: No Supports: Yes Resolution: .1mm Infill: .40 Notes: Print this slow @ ~ 30mm/s. Also print at the upper end of your filament to get the best layer adhesion.
