Yeah their both 2 piece mounts. One is a warne the othe is leupold. It doesn't matter how you do it.Its machined to close for any tolerance. Remington want even reply back on emails,and you sure can't talk to nobody. Businesses are a joke now days.online they want you to read all the FAQ. Anything to stall you a little longer. Who wants to read a bunch of answers that has nothing to do with your problem. I'm not going to let someone drill it, shouldn't have to.Remington products have went down hill this will be the second firearm I have had to return.
