Expensive scope mounts: what am I missing?

[sigstroker]

Same thing I thought when I had to buy rings. I was lost, actually with so many options. I ended up going with a 1 piece game reaper ring/mount. I put it on my 270Win and its works great. Not the cheapest, not the most expensive - but the easiest by far.

Because the rings are integral with the scope base, you won’t encounter any potential misalignment between the front and rear base.

I wouldn't take that as absolute gospel. That's the theory behind 1913 rails too, but things can flex when tightened down on the receiver. To make sure, get the Wheeler scope ring lapping set and check the turning centers ring alignment things that come with it.

67Cuda -- would you mind telling me the name/brand of the scop base/mount on your M1A ??

What I like about this mount is that if the scope comes off, using the the quick release mounts, the iron sights are usable.

In my humble opinion most shooters don't tighten there scope mounts or rings down tight enough and that is probably the biggest source of large groups bad shooting rifles.

And you can always add a third ring if you feel it is necessary.
This applies to hunting,Benchrest,F-Class,NRA Highpower, Silhouette and general shooting.
If you shoot tactical were your hanging out of a helicopter or using your scope to break open a bank vault while clubbing seals with it by all means get the 12 screw ringsets with boron bolts and nickel cobalt clamps.

I think it important to remember that not all scopes are fulfilling the same purposes. An uber light scope, or one designed to set and forget, might not have the same rings needs as something like a high travel externally turret driven scope is design for.

On high travel scopes, some will choose to spin the turrets instead of using reticle holds. In some types of uses, this might mean that the turrets are spun well over 100x in a weekend, many weekends per year. The tracking can be greatly degraded by over torquing the rings, narrow rings may require more torque to hold, and worsen the issue. It might be totally un-noticed to someone who primarily sets their scope and occasionally re-zeros for a new distance, but if you box testing you can see the damage distorting the tube can inflict.

Just a note of enforcement to my own stupidity as stated earlier in the thread, but I have damaged several high $ scopes over the years by over torquing them; Unfortunately, it sometimes doesn't take much to screw with the erector assembly.

Here is an externally adjusted scope mount on a US Optics SN-9. The externally adjusted mount works the same as a Posa-Mount from Unertl or Mitchell.
The front is non elevating just a swivel joint and the rear does all of the work.

On an internally adjusted scope it is a tube inside of a tube arrangement with the front of the tube hanging from a hooking/pivoting point while the turret once again moves the rear. The turrets push on two sides of the inner tube and spring pressure holds the inside tube against the turrets.
This is also why you should never bury you turrets to there full range of travel. You essentially have that inner tube pinned and now your forcing it to move which puts stress on that front mounting location of the inner tube.
The larger the click value is the easier it is to get repeatability as the spring/springs have an easier job of keeping the inner tube against the turrets.
The proper way to stress free mount a scope is the open up the internal diameter of the rings and epoxy bed the scope. By doing that you have eliminated the forced straightening applied by lapped rings on a non concentric scope tube.
To test the concentricity of your scopes main tube you can set it in a set of vee Bloks and rotate it while observing your dial indicator.
If you look at my earlier picture of the Calfee Benchrest 22 note it has 2 Weaver rings both on the same side of the turrets.
When you clamp a scope down on both sides of the turrets and allow the aluminum/steel main body to heat up in the sun you are stressing the scope.
You can set your rifle up in your backyard on a rock solid rest and place your crosshairs on a target. Do this early in the morning and comeback every couple of hours to see if your point of aim ever changes.
As I said earlier most scope problems come from loose hardware but you can also overtighten your rings and damage a scope like Diver has done more than once.
It's the last weekend of B-Zone so I am leaving for a hunt with Weaver rings on a muzzlebraked lightweight rifle.

Is that a hacked up M60 bipod?

But they are so nice....

What sight is that?
