Kroil
 

Best....stuff......ever. Put it on the rear sight mount screws on the TC barrel, waited a few, all came out with no problem. Now on to scope mounting

Love that stuff. Used it many times to removes rusted bolts, nuts, and screws.
Always keep a can handy.

I'm putting a scope on a 10 inch .223 barrel for the Contender the Colonel sent Jake. The thing is a BOOMER

Now that sounds like a great fun tool and a potent weapon. I am going to check that out. I really like the 223 in my black rifle.

I've never used it. is it better than wd-40?

Oh yeah. WD is a rust inhibitor Kroil penetrates quick

Kroil is great stuff! I have cans of it everywhere. The little cans last forever and the aerosol works on big stuff. Takes off rust too.

KROIL is 'the stuff', been using it forever. If you've never used it buy some, you'll never use anything else after that!

I've been buying PB Blaster for use at work. In a chemical environment, unless you use all stainless, common grade nuts and bolts get corroded quickly.

Just remembered, if interested ? .... the last time I had to order some KROIL I ordered the 8oz can and received a free can of KROIL aerosol through this section of their site:
