Spr1985 Posted November 30, 2021 Report Share Posted November 30, 2021 Good evening everyone, I’d like to pick the pigeon watch collective brain, is it possible to have the thread of a choke re cut? And is it safe to do so? I bought a choke (used) for wildfowling some time ago and the wife “filed” it in a drawer! On finding it I went to put it in the semi auto only to find it wouldn’t screw in 😞. I inspected the threads and noticed some deformation but really had to look for it, unfortunately it’s way beyond the time scale to get a refund so I’m now clutching at straws. Hoping someone can give a definitive answer based on experience. Thanks in advance 👍🏻 Quote Link to comment Share on other sites More sharing options...
Cawdor118 Posted November 30, 2021 Report Share Posted November 30, 2021 Am I correct in saying its the choke thread that's damaged rather than the gun thread? If so, yes it can be restored with a thread file and a little patience. Just go slow and with not to much pressure. https://www.cromwell.co.uk/shop/cutting-tools/thread-restoring-files/thread-restoring-files/f/61 Quote Link to comment Share on other sites More sharing options...

It was at that point that I inspected the thread in greater detail. Thanks for the link I shall check it out 👍🏻 Quote Link to comment Share on other sites More sharing options...

enfieldspares Posted December 1, 2021 Report Share Posted December 1, 2021 (edited) Personally I wouldn't do it. Too much potential risk of liability if (now of course it never ever will...it is hoped) if the think flies off down range with a wad carrying it thus and it strikes and injures or kills someone. As the very first thing that'll be raised is that your chasing, re-cutting, filing or whatever, the threads made it do so. I'd bin it.

Gunman Posted December 1, 2021 Report Share Posted December 1, 2021 Best recommendation is to throw it away . I doubt that you will get a tread file suitable and unless you can find someone with a die of the correct thread then you risk further damage to the choke as well as to the threads in the barrel .Unfortunately I've seen quite a few barrels with the internal treads damaged for people attempting to either adapt chokes or to " repair " threads . II would suggest taking advise from a professional Quote Link to comment Share on other sites More sharing options...

Spr1985 Posted December 1, 2021 Author Report Share Posted December 1, 2021 Thanks for all the advice. @TIGHTCHOKE it’s had beretta own brand, briley, Teague and muller chokes in and out of it all with no issues at all, no damage to any of the chokes and all screw in smoothly and seat down correctly. when I tried the damaged choke (not realising it was damaged) I stopped the second it felt odd.

Jaymo Posted December 1, 2021 Report Share Posted December 1, 2021 Are you sure it’s the correct choke in the first place? Not a different models thread? Quote Link to comment Share on other sites More sharing options...

It was sold to me as a beretta optima hp choke and the threads look the same as the other optima hp chokes I have. so I can only assume it is the correct thread pattern.

Jaymo Posted December 1, 2021 Report Share Posted December 1, 2021 As you purchased it used, it’s my feeling that the previous ( or other) owner tried it in an ‘non’ optima gun? The flatness of the threads in comparison is quite pronounced ( or it it just the pic quality) Quote Link to comment Share on other sites More sharing options...
Spr1985 Posted December 1, 2021 Author Report Share Posted December 1, 2021 I think it’s the pic quality but I do see what you mean Quote Link to comment Share on other sites More sharing options...
