wymberley Posted April 25, 2012 Report Share Posted April 25, 2012 How do u find out what thread size is on a rifle. To be honest, if you need to ask it's probably fair to say that you haven't got the necessary kit (simple as it is - if you know) to measure it. So half decent RFD or gunsmith. I wouldn't rely too much on someone saying, "see if mine fits, I know it's 1/2" UNF", or whatever. Quote Link to comment Share on other sites More sharing options...
Graham M Posted April 25, 2012 Report Share Posted April 25, 2012 Measure the width and then count the threads. If it's ½” wide and there are 10 threads per ½” of length then it's ½” UNF if there are 14 threads per ½“ of length then it's ½” UNEF. If it's bigger than that, then take it to a gunsmith and ask because there are a plethora of sizes to chose from these-days G.M. Quote Link to comment Share on other sites More sharing options...

Salopian Posted April 25, 2012 Report Share Posted April 25, 2012 Use a thread gauge and a micrometer Quote Link to comment Share on other sites More sharing options...
bedwards1966 Posted April 25, 2012 Report Share Posted April 25, 2012 Unless you have vernier callipers or a micrometer, as well as a screw pitch gauge you need to take it to a gunsmith, engineer or maybe even a RFD. Quote Link to comment Share on other sites More sharing options...

Because he won't have a full inch of thread to measure I said it was 10 threads per HALF inch UNF and 14 threads per HALF inch UNEF. G.M.

Unless someone has had a different thread made for it, which is probably very unlikely. Quote Link to comment Share on other sites More sharing options...
