I picked up this kit to upgrade my Beuchat Marlin Aluminum 95cm to a roller. I chose the roller "pro" option for Beuchat and installed it in about 45 min. There was a little bit of sanding the muzzle to get a perfect fit, but nothing too hard. All I used to fit the muzzle was a piece of 100 grit sandpaper, a drill and some 100% silicone sealant. My kit came with a stainless steel screw to secure the muzzle to the barrel and instructions how to rig the bands (not extremely descriptive). Running the shooting line correctly was a little bit of trial and error, but I eventually figured it out. Be advised, this kit does not come with any bands or rigging line. Make sure you have about 4 feet of band rubber, shooting line with crimps and crimper and 15 feet of dyneema, spectra or another type of band and rigging cord. I have taken the gun into the water twice, once to shoot target, and it's dead accurate. The big question is, "how does it compare to a standard 2 band set up" I am getting more accuracy and similar terminal range with a single 5/8" band as I was getting with (2) 9/16" bands. Basically it's the best of both worlds: accuracy and power. If you're not afraid to tinker, this is a great kit for the money. Here is a link to a video I found helpful, although I set mine up without a reel and a double wrap shooting line. The video just gives a general idea how to install a aftermarket roller muzzle.
