If the sprue is in the ramrod hole, it is no biggie. I cut them off and install another one where I want it quite frequently to get everything to line up the way it should.
If you need to cut it off, just whack it off with a hacksaw. Then, cut a piece of 1/8 inch brass an inch or so long, and 3/8 or so wide. I attach it to the guard by drilling a hole in the guard at the center of the new location. I drill the hole just a little shy of 1/8" in diameter and chamfer the upper side of the hole.Then file the sprue so as to end up with a round post in the center of the top of the sprue.
Stick that post through the hole and peen it down to fill the countersink (Like a little rivet.) I also solder it once it is in place, but that is probably not really necessary. Now you have your sprue right where it needs to be.
