The point is that Ruger wouldn't send any part for the OM unless I sent it to them for a transfer bar mod. 5 minutes with a Dremel, no nub, and it fits just fine. Now, it's off to the range with a $40 box of Am. Eagle 110 gr FMJ. It's a good thing I'm not buying for an M1 carbine, as much as I'd love one, couldn't afford to shoot it!
