I had a OLD TC and I got the BP Off because the person I got it from gave it too me bacause he got a Ball and a Ball Puller stuck and broke off in it. I put the Barrel in a Vice and with a pair of Vice Grips with a towel wrapped around them and some Brute Strength I got that sucker off. It was'nt pretty and I left a few marks on the BP, but if it went on, it'll come off. Now Im not saying it'll work with all BP's but it did on this one and Im sure it was'nt ment to ever come off.
