Opmod ar15 upper reciever reation tool - OpticsPlanet Exclusive Midwest Industries OPMOD AR15 Upper Receiver Rod - Nickel

I would like to say this tool is a must for AR15 builds. I particular like the nickel coating which not only makes the rod esthetically nice, and the nickel will help prevent rust and scratches which can be seen on the blued model. The rod is a great tool to use for torquing down the barrel nut to the upper receiver, not only does it align the barrel and reciever it prevents the receiver damage to the guide slot on both mating parts. My wish is that Optics planet and Midwest should do an OPMOD version of for the AR10. Keeping my fingers crossed.
