    I just purchased a well used but sound BT-99 as a project gun to build up and restore as a trap gun for my wife. It has 4 moon shaped ports milled into each side of the muzzle for recoil management. I have never seen any ports like this before.

    Does anyone know who used to do ports like this (one friend mentioned Herb Orre).

    I am unable to post photos but the job was well done. Any info or insight will be most appreciated. Jess

    Great question as I have the same porting on my TMX. Have no complaints with it at all but it did melt the legs off of my light pipe front sight. Thanks for the info. Bill H.

    I had them on a Miroku, and they ended up splitting between the ports. Ended up with a 26" cyl./cyl!
