impala59 Posted October 12, 2023 Report Share Posted October 12, 2023 I’m sure it’s probably been asked before, but any tips on removing a stuck Rem choke? I bought a Premier Skeet 1187 for very little at an auction, obviously expecting some problems. I was proved right but corrected the functioning issues in a few minutes. A bent latch prevented the floor plate release and an excessive crimp on the mag tube caused a distortion which slowed and partially jammed the piston ring. The usual gunk, carbon, grease, unburnt powder etc pointed to a poor performing, neglected shotgun. It has cleaned up well and all mechanical elements are now correct. My problem is the choke tube currently installed, it will not budge, I tried a little heat (heat gun not flame) but to no avail. I have left it muzzle up with penetrating oil in the hope that it will help to break the rust/carbon seal. Any advice would be gratefully received Quote Link to comment Share on other sites More sharing options...
d3ets Posted October 12, 2023 Report Share Posted October 12, 2023 Muzzle down in a small container of penetrating oil (enough to go the full depth of the choke)? Quote Link to comment Share on other sites More sharing options...
ditchman Posted October 12, 2023 Report Share Posted October 12, 2023 speaking to my gunsmith over the years...if he gets a stuck screw or choke ..it is usually soaked for at let a couple of days first before removal Quote Link to comment Share on other sites More sharing options...
old'un Posted October 12, 2023 Report Share Posted October 12, 2023 depends on what's holding the choke in, gunk or rust, try this...get an empty tin-can (bake beans can size) mix 60-40 oil and turps, get the end of the barrel fairly hot and dunk into the can and leave for an hour, you may need to repeat this until the choke starts to move. If its rust and depending on how bad it is, that's a different ball game. Quote Link to comment Share on other sites More sharing options...
scarecrow243 Posted October 12, 2023 Report Share Posted October 12, 2023 soak in diesel over night this usually works Quote Link to comment Share on other sites More sharing options...
Red696 Posted October 12, 2023 Report Share Posted October 12, 2023 Could you not use a gas soldering torch internally on the choke to get enough heat in without risking damage to the bluing on the barrel? Quote Link to comment Share on other sites More sharing options...
impala59 Posted October 12, 2023 Author Report Share Posted October 12, 2023 Thanks guys for all the tips, I have a few to try now, I will start with the immersions hope for the best! Quote Link to comment Share on other sites More sharing options...

This will only expand the choke onto the barrel. You need to expand the barrel off the choke. When warming the barrel stop before the choke itself gets warm or they will both expand together Quote Link to comment Share on other sites More sharing options...

It may take several cycles Quote Link to comment Share on other sites More sharing options...

NO, not unless you REALLY know what you are doing ! I bought a 'scrapper' 300 Beretta which has a 303 multi choked barrel on it. The end of the barrel is permanently marked with a blueing effect, due to some clown using heat. I have released several 'stuck' chokes ( none mine) by standing the muzzle in diesel oil for a week. As also mentioned on here, put the choke key in a vice and slide the barrel down over it. It does give more leverage. Quote Link to comment Share on other sites More sharing options...

Westley Posted October 15, 2023 Report Share Posted October 15, 2023 But, if you do not know what you are doing you can possibly ruin a decent gun, that was my point. I have NEVER been beaten by a stuck choke, but neither have I had the sphericals to use heat ! Quote Link to comment Share on other sites More sharing options...
BlaserF3 Posted October 15, 2023 Report Share Posted October 15, 2023 How about buying one of these? https://www.shotgunchokes.co.uk/webshop/shotgun-accessories/shogun-choke-stuck-removal-tool Better than damaging the gun. Quote Link to comment Share on other sites More sharing options...
impala59 Posted October 19, 2023 Author Report Share Posted October 19, 2023 Well I got it out, eventually! I tried all the immersions to no avail. I then tried heat, a hot air gun first, again, without success. I am converting this gun to a dedicated slug gun, the full choke just had to go and I decided that I would have to risk the finish and lump it if it was spoiled. To be honest, if it had been a 28" or more I would have just cut the rem choke out! I proceeded with the torch and tried everything I could think of. I broke two choke keys with no movement. A mechanic friend suggested trying plus gas as a thinner solvent/release agent, it may penetrate better. still no joy. I had melted the plastic bead but the blue was holding up. I decided that I would have to sacrifice the choke and with the barrel in a wooden made to measure clamp, (to protect the integrity of the barrel tube and rib) I hammered a shallow reamer into the choke. Gripping the reamer with large mole grips, I tentatively put my weight into it. A slight creak and an eighth of an inch of movement! repeating the Plus Gas and reamer and 2 hours later success! Surprise surprise, traces of green thread lock (possibly loctite 270) on the threads. Why would someone buy a multichoke gun and then threadlock a choke in? Second surprise, the full choke survived the ordeal as did the blueing, a bit of cleaning up and I have installed my cylinder choke and now ready to move on to the next mod, fitting a scope rail and speedload ramp. Thanks again for all suggestions, I am sure that in most cases they would have worked, this was just a very hard nut to crack! Quote Link to comment Share on other sites More sharing options...
