ORIGINAL: roundball
I don't happen to like the QLA feature...I had a .54cal QLA barrel back in the mid 90's when they came out with them...took it to the range one time, sent it back to TC to get it exchanged for one W/O a QLA...never owned one since.
Reading this, I have to wonder if T/C might exchange non-QLA'd barrels for the omegas which have shown inability to accurately shoot conicals. I take it roundball's rifle was a 1" hawken or renegade barrel, and it was ten years ago . . .
