I just got off the phone with Briley...I told them I had a 12 ga. damascus barreled hammer gun I wanted to get a set of 20 guage tubes made for.

He asked me "if it was a 2 & 1/2" chambered gun ?"

I answered yes all original...he told me they couldn't make a set for a 2 & 1/2" gun...unless I was willing to let them cut the chambers to 2 & 3/4".

Guess I won't be getting a set.
