Evolution M40 project is going to be more complex than I thought... Stock barrel is about 480mm and is bridged, so the maple leaf rubber won't go on it. Also, the hop arm doesn't use a nub, so can't put the omega on.

It's not the end of the world. I think I can get away with a Maple Leaf Crazy Jet 470mm barrel, maybe pop in a couple of barrel spacers to be sure it's nice and aligned as the way the stock barrel handles that is the end cap is the spacer, and I'll also swap out the hop arm for the Maple Leaf arm, either the concave one or the one with the I-key. Should still work, just will take a bit more than simply swapping out the rubber
