aerosigns Posted March 16, 2007 Share Posted March 16, 2007 Does anyone know where I can locate and buy a bore straightness gauge for .223 AR-15's. Thanks. Link to comment Share on other sites More sharing options...
Dan Sierpina Posted March 16, 2007 Share Posted March 16, 2007 You might try a reamer grinder. Someone like JGS or Pacific Tool and Gage. My curiosity has me, Why? Link to comment Share on other sites More sharing options...
aerosigns Posted March 16, 2007 Author Share Posted March 16, 2007 There is a gauge that is just a straight rod. You drop it through the barrel. If the barrel is straight it falls right through. If it is bent it sticks. Pretty simple process. I am an armorer and need it in my arsenal of gauges to check during inspections. Link to comment Share on other sites More sharing options...
Dan Sierpina Posted March 16, 2007 Share Posted March 16, 2007 I do know what they are. Now I know why you want one. Like I said, try JGS, or Pacific Tool and Gage. Good luck with the search. Link to comment Share on other sites More sharing options...
North Posted March 17, 2007 Share Posted March 17, 2007 http://welcome.gsgage.com/ These flks will make what you want fairly cheap. I've ordered stuff from them in my Job, USAF calibration lab. All you need is a 6-8 inch plug gage. Just Specify the Diameter, if you don't know it, I'll check on monday and post back. Link to comment Share on other sites More sharing options...
aerosigns Posted March 17, 2007 Author Share Posted March 17, 2007 (edited) North, Thanks. These are also called a deltronic pin sometimes. I called Deltronic, but they don't make them anymore. Of course. I didn't know it would be this tough to find. They actually list this gauge in the military manuals. So I thought about looking it up in a manual, then web-search for that part number. As far as the Min-Max number, I don't know what it is. I could also try to find time to check with one of the barrel manufacturers.
