Thanks guys. I had always thought those tubes were steel. Aluminum makes a lot more sense.
I'm not too worried about looks. That sucker is going to be ringed from the end of the ocular to the end of the objective. Since y'all have pointed me in the right direction, I've found pics of scopes with 4 rings on them. That's what I'm going to do. The ugly spots won't even show.
Grouse-I was going to use Loctite purple. I thought blue was permanent. If you need to get the scope off or out of the rings, can you do it with blue? I generally don't use Loctite and this is the only gun I've had a problem with. I'm Loctite ignorant.
