Hello, I have a set of 28 GA and .410 GA Briley 2.0 Side Kicks for a 20 GA barrel. I purchased them brand new a few months ago from Briley and used them one time. I used them in a 28" Krieghoff barrel but should work fine with any brand except Browning and of course any length of barrel will be fine. Check the Briley website if you are unsure as to your manufacturer. Both sets of tubes pattern great in a 20 GA barrel; great way to shoot all the sub gauges efficiently and effectively! Everything in the picture as new $425 shipped CONUS (I paid $350 for each gauge, $700 plus tax total) ....Thanks! 210-861-4074
