Just get it and it will change your world. - Midwest Industries Upper Receiver Rod

Don't try and go the "economy route", this is the best tool for the job. A little grease on the threads and time and you won't be disappointed. I have used all manner of devices, with varying degrees of success and my fair share of catastrophic failures. The most important lesson I learned along the way was never skimp on tools. Don't skimp, get this tool! Cheers!
