Andrew goes through the steps we use here to mount a scope to a typical rifle. We discuss tube diameter, tube length, eye relief and ring height considerations.
Redfield was a top American scope manufacturer 50 years ago People saved up to buy Redfield. They eventually sold the brand to Leupold who kept them running for a while but relatively recently the brand was sold to Academy Sports. Similar situation with Weaver. Very nice steel tube scopes from El Paso, TX, back in the day but now the brand is owned by Vista Outdoors Group. For some time now Tasco has been owned by Bushnell, a former competitor. There are still scopes and accessories being sold under the brand names Redfield, Weaver and Tasco but they are all price-point import scopes designed for the big-box and internet retail market.
In general, we avoid using threadlocker on rifle rings/bases. Quality rings and bases with correctly fitting screws, torqued to the correct values, typically do not benefit from being glued in place. There may be some benefit to using threadlocker on lower quality rings/bases where there is more slop in the screw thread tolerances. In most cases, threadlockers are over used and become problematic when it is time to remove or change the optic. Just as with alcohol and redheads, use sparingly for best results.
