Possum Hollow Bore Guides will do the same thing. I have a Lucas guide. It's basically a delrin straw. Nothing special about it. Having to deal with crappy communication and long wait times is silly when you can get the same thing with a different brand name on it for less, overnight. But if you gotta have a Lucas, you're gonna have to put up with the back and forth. It took me about a month or so to actually get one ordered. Had to send numerous emails and phone messages. Kind of a pain in the ass. By contrast, you can just hop onto any of the shooting supply websites and order a Possum Hollow or similar guide. Bore-Tech makes nice ones too.
