Feel free to use these model files in any way you so choose. Hack em, slice em, burn em, sell em, you're a free person, act like it. Check local laws before printing ANYTHING relating to firearms. Printer assumes all liability. I'm not your parents.

Warfairy will bless you if you actually print her in pink.

Instructions:

You will need to print 1 of each part except for the plug which requires 2, a spring that fits around the shaft of the adjustment pin closely, some glue to bind the Adjustment pin nut to the adjustment pin, and a small patch of fine grit sandpaper for fitting (600 for coarse, 800-1000 for fine sanding)

Preface

Printing of the stock body and butt pads should be done from back to front.

  1. Place spring on the skinny shaft of the Adjustment pin. Use a SMALL bit of glue to keep spring in place, applying the glue where the spring meets the adjustment pin head (thick part). Allow to dry.

  2. Place Spring/Adjustment pin assembly through hole in the top of the stock, ensuring it passes through so that the excess length of the adjustment pin falls through the hole in the bottom of the stock without catching.

  3. Ensure free movement by pulling on excess length a few times. It should pull down with some resistance and spring back to resting position. If it gets stuck, push the pin out and sand down the adjustment pin head slightly

  4. Take stock assembly in one hand and pull the excess adjustment pin length down until the top of the pin is not visible from the front. Apply stock to buffer tube and lock into place with adjustment pin. The stock should not move forward or back much.

  5. With the stock applied to your weapon, put adjustment rocker onto the excess length of the adjustment pin, with the textured patch towards the rear and facing downwards.

  6. Rough the surface of the adjustment pin slightly by rubbing the sandpaper across it once or twice, alternately, nick it three times with a sharp knife, just enjough to give the glue somewhere to grab. Put a SMALL amount of glue on the inner surface of the Adjustment Pin Nut and press onto the adjustment pin shaft until it just contacts the surface ofthe Adjustment Rocker. Allow glue to dry before operating Adjustment rocker.

  7. Press Butt Pad onto Stock Body, aligning the pins and bars with their appropriate holes. If need be, glue into place.

AND IT IS COMPLETE.

Cheers, and happy hunting.

Version

  • V1
  • Initial Release.
  • V2
  • Added recoil pad in addition to solid butt pad.
  • V3
  • Thin surfaces eliminated for (hopefully) easier printing.
  • Reinforced a few points where the buffer tube would put stress on corners.
  • Slightly increased diameter of interior surface to allow for variation in printing and buffer tubes.
  • Eliminated obstruction to battery tube plugs. They can now be rotated when stock is off weapon and the tab used to open.
