Recoil SR12 Gun Stock Extender

ADDED EXTENSION TUBES Aug 25, 2018 I added two additional extension tube files one that is roughly 3.25 inches in length and the other 2.25 inches in length. The original, larger tube is for a large adult. The medium and the smaller extension tubes fit an adult roughly 5'6 to 5'11 inches in height. It all depends on arm length. Fitting Suggestion: Print both end caps and loosely fit them on the SR12. Using stiff cardboard, make an extension tube you feel would be the appropriate length. Next tape the end caps to the cardboard extension tube and hold the SR12 into firing position and see how the gun with the added length fits. Available Extension Tube Lengths in This Model: Original - Large: 4.86" New - Medium: 3.28" New - Small: 2.38" NEW & IMPROVED MODEL! Aug 19, 2018 What I have put together here is a six inch gun stock extension for the Skyrocket Recoil SR12 Rifle. The assembly takes advantage of the power connections that seat together when the stock is snapped into the back of the SR12. Assembly requires 4 springs (available at Harbor Freight), 4 screws, 4 matching lock nuts, small piece of sheet metal (cut to make terminals for batteries) and wire. Print, assemble, and attach. Much more comfortable than without.
