I just bought a new dimmension and I have a question. I want to get a 50 mm scope and I only want to buy one scope and still be able to change the barrels. What size mounts would I need to get? Can I get low mounts and still be able to get the barrel off? I was thinking of getting a leupold vx-l with the cut out at the botttom so it mounts close to the barrel but I am scared I won't be able to get that barrel off because it would sit too close. What is everyone doing with theirs to get a 50 or a 56mm to fit and still be able to change it out? Anyone have any suggestions?
