SOPMOD Stock

thingiverse

Remixed from Rusty's design on GrabCAD to fit a milspec buffer tube. I've uploaded the original STL for the commercial tube as well. This design reuses the latch, pin, spring and nut from a standard AR15 adjustable stock. Plastic versions of those parts are basically worthless. Print with the buffer tube hole oriented up. No supports necessary, but you may need a raft to keep it from tipping over. I've updated the models with a MilSpec version that now includes locking plugs for the battery tubes. They use rubber bands or O rings to seal.
