RE: Scope mounting
Except for extreme application loctite is nothing more than added security. I use it on my 375 JDJ contender pistol for this security. On my tactical rifle I don't use or need it. Soft scope rings which do not hold torque need it. You might use that as a way to determine that you really need better rings.
To just assemble the pieces, is easy and that is what most shops do for like free to $50. With a one piece base, you should bed the base and rely on quality rings and bases to line up well. A two pc base definately needs bedding or lapping of the rings. Another alternative is the TPS bedding alignment jig for 2 piece bases. If ring quality is a slight concern, lap the rings too.
Last is the Burris Signature mount. These plastic inserts are probably the bestcheap way to mount a scope on a low or moderate(< 458 Win Mag) recoiling rifle. That is just a bolt on deal.
The last way is the $35 rings and bases. Your results are a crap shoot. It might be perfect, or it might kink your tube. Good luck. One thing you will know is it will not hold torque and will come loose when you want it to work, even with loctite. Also, dropping or banging your rifle slightly will result in the need to resight in.
