I found some limited information a*about a magwell adapter for the Ruger 10/22 and thought I'd share it with you.
Made by Bingham LTD back in the 80's (maybe still make them I don't know) it allowed your 10/22 to use 30 round metal mags (I believe to be made by Auto Ordinance)
They were supposed to be extremely reliable and most importantly for this current day and age not Ruger 10/22 mags.
Here is a link to a US sight that sells the adapters https://www.gunpartscorp.com/ad/1194440.htm
And here are some pics I found online.

I don't own a 10/22 but I thought those of you that do might find it interesting.
Cheers
