Was curious to see who has had this done? What gun, and thoughts on the process.
Thanks guys!

If you are talking about the Teague or Briley thin wall interchangeable chokes, I have had several done by Teague and they were brilliant, and I thought very reasonably priced, but it does involve reproof in the UK which can be a risky business nowadays. Really can barely tell they are there once fitted other than the line round the muzzle face.
They do also offer fixed chokes which are cheaper since you aren't buying a set but then you are stuck with the choice you make.
You will need good thick walls at the muzzle, I have had them decline a couple as they felt there simply wasn't enough metal to do the machining.
I have never had Briley do any for me but I have seen one that was done to a gun I sold, allegedly done by Brilay, and I was rather unimpressed: big recess at the back of the choke tube. But then there are no proof issues.

I was thinking permanent tubes, its for an older BSA field gun with some pitting at the muzzle, I was hoping the permanent tube would help alleviate some of the issues with the pitting and bring back some choke that was lost.

Toby, if RA is talking about a fixed choke sleeve, would it not be less of a problem with thin muzzles? I would think that the only issue would be the danger of damaging the muzzles in between the time they were reamed and the time the sleeve was permanently installed. With interchangeable tubes the danger of damage is there every time a tube is removed and replaced.

FWIW, I had Briley thread a very old Perazzi MX8, imported by Ithaca, for tubes about 10 years ago. It left the muzzle walls very thin, but they did an excellent job, I thought. My buddy at CompNChoke did lots of these jobs during that time, and he didn't want to do mine due to the thinness at the muzzles. He suggested I consult Briley and go with their recommendation, thumbs up or thumbs down, which I did. That said, I would not do it to that particular gun again. Why? I sold it to a good friend who wanted it. He shot it about a year and shot the end off one of the barrels, ruining the set. I thought he let a tube back out during shooting the round of clays, allowing plastic shotcup material to begin shaving off and packing under the rear of the tube, until it became an obstruction and "blew". But, he says that did not happen, so if it didn't the only other reasonable explanation is that the barrel wall was so thin at the threads that it eventually fatigued and failed. I have enough suspicion that he is right that I just wouldn't take that chance again with thin walled muzzles.

Yeah Stan is correct, it would be permanent sleeve to bring back the choke constriction lost due to the pitting at the muzzle. I have never seen a gun with this done, so I was curious to see if anyone here has had it done.

I have a pre WWI Merkel S x S 16 gauge that had the same situation of the chokes having been opened at some time in the past to dimensions that did not suit me. At least the left barrel did not, the right still had IC choke, which was o.k. for our southern walk-up bird shooting. I wanted the left barrel to be about Modified, so I called Brileys and talked to them about the job. I asked for an "invisible" permanent sleeve to be installed in the left tube only to give me that degree of choke. The guy I spoke with said it would be "no problem," they did it all the time, send the barrels to him. Well, to cut to the end of the story, after a much longer time period than they promised, they came back and it appeared they had threaded that barrel and simply installed an off the shelf choke tube in it, very visible, not at all what I had asked for. I called and asked for the same guy, told him what I had received back, he said send it back and he would see that it was done correctly this time. Well, it took another 4 months or so, but they did it right this time. I'm not sure how the sleeve is actually installed, perhaps either soldered in or maybe even some super adhesive, but it is invisible, and the gun now has about 8 thousandths right and 18 thousandths left, which suits my needs fine. I have shot it hundreds of rounds since that time (about 12 or 13 years now) and the sleeve is still in place and I am pleased with it. So, Brileys can do the work, but I would be very clear with them about what you want done, so hopefully they get it right the first time.

I saw Oscar do it to Parkers, the choke was solf soldered to the old choke area.

Mike Orlen used to do these, I think. There was an article years ago in one of the online gun mags that showed the process, using Loctite Black for a permanent bond.

Mike still advertises, I sent my barrels to him for the work, but wanted to see if anyone out here had it done.

I had Briley do a permanent choke sleeve in my M 21 Skeet gun which then gave me .009 in both bbls. It is near invisible and has worked very well
