TM SGR-12 Auto Bolter

thingiverse

This kit fits perfectly over the TM SGR-12 without requiring any modifications or screws. To begin, simply remove your existing metal receiver by unscrewing the six screws from each side and two large screws underneath. The metal receiver should slide off in two pieces. Step 1: Mount the rear cover with Mlok sections and use the stock screws that were previously installed. Step 2: Mount the center piece and screw both sides into place. Step 3: Attach the small grip extension underneath and secure it using the large stock screw. Step 4: Insert the faux cylinder and rectangle into the front end. If necessary, apply glue to ensure a secure fit. Step 5: Glue the skullwings onto both sides or leave them off and create your own custom icons. Step 6: This part may require some patience and finesse. Slip the front over the barrel and lower it carefully, ensuring that the indexing tabs are below the faux gas block rails while keeping the gas tube in the upper portion. Secure the piece with the last screw on the bottom. Step 7: Press fit the new muzzle over the old one, aligning both holes on the sides. This process also indexes the front end, ensuring it sits straight and level. Thanks to everyone for the enthusiastic support! Feel free to modify this design as it is my first time using CAD software. I'm sure there are areas where improvements can be made, and mistakes were likely made along the way. UPDATE: 12/29/18 A new skullwings file has been uploaded. I recently printed them and found that one of the skullwings was not printing correctly during the first few layers. Additionally, a smaller version of the file has been uploaded for your convenience.
