AR Style carry handle to fit on the 1913 picatinny of any rifle or Tacticoozie. Included in the parts for this are models of the required equipment with part numbers from McMaster. 2x #10-32 x 1 1/8" cap screws, 2x #10-32 Nuts, and 1x 8-32 x 7/8" Button Head Cap Screw. The peep sight and adjustment knob will need to be tapped with a #8-32 tap. The carry handle is designed to slide onto the picatinny rail. I will adjust the model when I print one and test for fitment. Enjoy!
