If I get this right, you'll have a picture of the bumpers. The Bumper on the bottom is the "new one" from Bumper Boy. I added the streamers. The one on top is the bumper I got from Gun Dog Supply. They are both about 7" long with identical inserts. The GDS bumper compressed after a few shots (I put the black tape on for visibility). That's why is is a little shorter, now. It's covered with canvas, and I don't expect it to hold up for a very long time. It's already showing some dents and snags from dog teeth. The BB bumper is covered with what appears to be heavy-duty nylon, and is holding up well. I've probably launched these bumpers less than 15 times each, and they are already soiled. I had 4 other bumpers with the streamers attached, and even going down to the lighter green loads, they still blew off at the launcher. These bumpers are just too light. In Kansas, the wind blows, and even with light loads, they carry. I Launched them into the wind with a green load and a 2" spacer, and the bumpers landed 20 yards behind the launcher. I'm still going to order at least one more 4-shooter, but it kind of irritates me that they still show the original bumpers for sale. Seems a bit like false advertising to me. I'm going to keep on experimenting to see if I can come up with something that will work better. I'm thinking about covering one of the bumpers with a thick coat of liquid latex to add some weight. Still don't know about attaching the streamers. I'm thinking that, if I attach them to the front of the bumper instead of the rear, they might stay on. We'll see...
