NO MIL-SURPLUS RIFLES SHOULD BE FIRED UNTIL HEADSPACING IS CHECKED! Your face and hands are much too valuable to risk by firing old battle iron without checking for safety first! Clean thoroughly all old mil-surplus guns and then check headspacing on the rifles (or pay a gunsmith to do it for you). Here are some resources so that you can understand what headspacing is all about, what and how you need to do it, etc. Be aware that with a C&R FFL, places like Brownells and Midway offer you a dealer discount. Brownells does not discount some tools (which means some headspace gauges are sold by them at list price to everyone). http://hybrid.ualr.edu/satu/headspace.html http://www.fulton-armory.com/headspace.htm http://www.cruffler.com/trivia-October99.html http://www.clymertool.com/headspac/index.html http://hometown.aol.com/yankeng/myhomepage/business.html - NOTE: This is a very local company, don't know much about them.
