The fix for the mag box is simple. Ten minutes with a Dremel and the protrusions are ground down a little. I measure the mag box before I start grinding with a caliper. I try to take off about .050".

I don't want to remove too much, just enough. I reassemble the rifle -- minus the follower and spring -- and torque accordingly. Open the bolt, stick a couple fingers in the action and make sure it has a little wiggle room. If the box is still binding, it won't budge. It should move a little side to side at this point.

If all is good, I polish the metal a little where I've been grinding and hit it with a blue pen.

I enjoy handguns and I really like shotguns,...but I love rifles!
