I just find it odd that Briley will go to the trouble to build a custom choke to match the internals of your bore when they can't build a set of full length tubes to match the chambers in a gun.
Example I had a 3 & 1/2" 10 ga. that I had a set of full length tubes made for...the chambers on the tubes were made for a short chambered 10 ga. after they were made I questioned them about it I was more as less told take it or leave it.
I've talked with them more than once about building a set of 20 ga. tubes for a 2 & 1/2" chambered 12....they refuse to do it without lengthening the chambers on my gun.....Taking it out of proof.
I guess they figure they can make more money selling custom fitted choke tubes...that are probably made in China.
