I have the Charles Daly 28 gau auto loader 26" with syn stock.
It is not in that league but it works great.

I have shot a 48AL ,it had some problems with light loads. I think he got it fixed.
It is a scaled down A5 ,I think.
I am not a fan of recoiling barrels on shotguns, some do ,to each their own.
I some times rest my finger on the barrel ,a barrel recoiling gun jams when I do it (and my finger gets sore) . Bad habit I picked up shooting a single for trap.
