Don't know anything about them, another barrel supplier would be good.
Lilja's had replacement 22LR barrels for a couple months now. There's a few threads about them including 2 of my own. Last time anybody talked to him the Mach II barrels were a ways off though. He wanted to get the HMR barrels out first.I was talking to Dan at McGowan barrels and he said he would make me a 17 mach II barrel and a 22lr for my 455. No one seems to have 455 barrels in 22lr available. ive got the 17hmr for an american i found at a lgs. my rifle came as a22mag. Has any one used McGowan barrels I was wondering how the accuracy is with them.
