nvhunter. Hate to burst your bubble, but you will need to clean the breach plug on the Omega and I'm sure on the Knight Disc as well. I have two ML. One is a CVA Appollo which is a real pain to clean, but is a nice beginner gun. I recommend beginning with a moderately priced ML and then work your way up as you develop a greater interest for ML. If $$$ is no object, then I strongly recommend the Omega (Not having shot a Knight myself).
My Omega is extremly easy to clean, especially if using Tripple 7 powder (Does not contain sulfer like Pyrodex or Black Powder). Unfortunately, my biggest cleanining problem with my Omega is the breach area.
Since you are new to ML, you may want to read up on BlueTick ML101 found on this web site. Most importantly of all, ML takes a lot of patience and requires time to care for your weapon.
Best wishes and welcome to the club.
