tbirdsc Posted September 12, 2019 Report Share Posted September 12, 2019 Hi AllI just picked up this A-O Thompson M1 manufactured in 1999 and I am trying to figure out how the front sight is mounted/attached. As you can see from the attached pic, it is not pinned in place. I contacted A-O about it and sent them the same pic, as far as they knew, all front M1 sights are now and always have been pinned in place so no help there.So was the front sight threaded at that time like the Cutts and lock-tited in place or is it not threaded and just a slip fit and lock-tited in place. It seems to me that the adhesion would be better using a threaded barrel vs a smooth barrel if that is the case.As usual, thanks to all for your help Link to comment Share on other sites More sharing options...
tbirdsc Posted September 12, 2019 Author Report Share Posted September 12, 2019 (edited) Just occurred to me now - the barrel is probably not threaded as you would see the thread run out Edited September 12, 2019 by tbirdsc Link to comment Share on other sites More sharing options...
BillyDixon Posted September 13, 2019 Report Share Posted September 13, 2019 possibly pressed on and locktight glue. Link to comment Share on other sites More sharing options...
TSMGguy Posted September 13, 2019 Report Share Posted September 13, 2019 Any WH has a pressed-on front sight or comp, including full auto versions. Sometimes they loosen up, sometimes not. It's one of the things that any owner will want to consider correcting. PK did mine as part of a through rebuild and refinish. Here's a pic of a WH M1 front sight that has yet to be properly pinned: Link to comment Share on other sites More sharing options...
