Customized version of WarFairy's Minimalist Stock, enhanced with a flexible cushion grip. Attaches to milspec buffer tubes by way of a .3" roll pin. The perfect compliment to a 7.5" or 10.5" upper.Printed the stock itself using ABS Polycarbonate, 100% fill. I experienced some lifting on my first three attempts, finally found a fix by applying blue tape to the bed and brushing on a light film of acetone ABS slurry. Issues are probably related to me and my novice-ness. Butt Pad (haha) was printed using flex TPC polyester. Had to slow the speed way down, like 60%. I went with 20% fill, but if I was doing it again I would go 10-15% to enhance the cushion aspect. Don't mind my glue issues, I'm sure you'll do much better.
