Sold the gun that I used these in. 12 guage inserts to shoot 20/28/.410 These are a short tang ejector set. 20 g. has Ceaser markings, rest are blank. I’m pretty sure these won’t work in the longer throw Browning guns. You will need to talk to Briley to confirm. Should work in Perazzi, Beretta, Ceaser, etc….. see pics for condition $425 shipped to 48 Pm me for any other questions
