An AR style buttstock with horizontal and vertical adjustability. The cheek rest can be adjusted by loosening the knobs and the whole assembly can be moved along the buffertube by pressing on the lever.
Requirements:
- M4x30mm bolt + M4 nut (lock nut would be better)
- 2x M5x12 hexagonal bolt
- Small spring 7mm OD, 5mm ID, 12mm long
Assembly instructions
- The first step of the assembly is to put the small spring on the threaded end of the M4 screw. This screw can than be inserted into the hole on the top of the stock, untill the thread comes out of the hole in the bottom of the stock. You might need to hold the stock upside down to prevent the spring from falling off the crew when installing.
- The next step is to install the lever in the designated cutout on the bottom of the stock with the arm with the hole pointing towards the rifle. The lever can be secured in place with the M4 nut on the M4 screw. The screw should stick about 7mm out from the underside of the lever. You can now test the lever function by pressing on the long arm of the lever, the M4 screw should go down in this case.
- The next step is to attach the cheek rest by placing the two M5 screws in the two knobs and screwing them right into the stock with the cheek rest in between. The assembly of the stock is now done.
- The final step is attaching the stock to the buffer tube. To get the head of the M4 screw in the slot on the bottom of the buffer tube it needs to overcome the initial wall of the slot. This can be done by pulling on the underside of the screw until the head is flush with the bottom of the inside of the stock. The stock can now be slided onto the buffertube, and by releasing the screw, it should be locked in place. The position can be easily adjusted by pressing the lever, moving the stock and releasing the lever.
It is designed to be printed with the rear on the build plate. You might want to add a brim to make sure it stays on the build plate.
