10 ga with chamber mates?

[USAFTurkey]

Anyone using a 10 ga with 12 ga chamber mates?  Just wondering how it's working.

I don't see them on their site. Do you use them?
Most of the products they have listed say they are Unavailable.

Found this on their FAQS page.

There is not enough wall thickness to safely cut ejector slots for the 10 gauge to 12, 16 gauge to 20, and 20 gauge to 28 gauge, therefore those conversions will not be available.

If that's the guy on eBay , I contacted him some time back and we went into discussion over the possibilities , with focus on the chamber length on a 3.5 12 gauge to 20 gauge adapter , and a 10 to 12- I have my reservations about someone using a 3" 12 ga  adapter in a 12 ga /3.5"  chamber firearm , and putting a high PSI/BAR sub gauge load like a 3" 20 ga through it

other than a few back and forth conversations , I haven't heard back from him , and I am not sure on what is being made or offered today 

I would say that a shell adapter would be a nice item to have stowed away on the stock of a survival gun , you never know how desperate or how bad your ammo supply could get in a crisis

Look up gaugemates they run about 50$ .

They make a 10 ga adapter to use 3.5" 12 ga shells

I have used one. it was a one shot deal. I had to drop a rod down the tube to knock it out.
It lets me shoot 12 gauge shells to sight the 10 gauge guns.
