Bang-bang-bang - Carlson's Beretta/Benelli 20 Gauge Replacement Flush Mounts

I ordered 3 choke tubes and they arrived quickly but I had to return one. Actually, 2 tubes were back ordered. I called OP and told them what was going on. I was able to return the tube I received...as advertised. The other two tubes were cancelled. I have an oddball shotgun and was trying to get 3 tubes that fit but...bummer. I will say they appear to be well made and should function as OEM parts. If I find the right make and model, I wouldn't hesitate getting Carlson tubes.
