The visibility ring on my Buckmark reflex sight is EXTREMELY hard to move from one position to the next (0-7). Is this normal or is there an adjustment or lubrication I need to make/add? Thanks

Reflex Testing

Reflex testing incorporates an assessment of the function and interplay of both sensory and motor pathways. It is simple yet informative and can give important insights into the integrity of the nervous system at many different levels.

Physiology of Reflexes

Assessment of reflexes is based on a clear understanding of the following principles and relationships:

Tendons connect muscles to bones, usually crossing a joint. When the muscle contracts, the tendon pulls on the bone, causing the attached structure to move.
When the tendon is struck by the reflex hammer, stretch receptors contained within it generate an impulse that is carried via sensory nerves to the spinal cord. At this juncture, the message is transmitted across a synapse to an appropriate lower motor neuron. An upper motor neuron, whose cell body resides in the brain, also provides input to this synapse.
The signal then travels down the lower motor neuron to the target muscle.
The sensory and motor signals that comprise a reflex arc travel over anatomically well characterized pathways. Pathologic processes affecting discrete roots or named peripheral nerves will cause the reflex to be diminished or absent. This can obviously be of great clinical significance. The Achilles Reflex (see below) is dependent on the S1 and S2 nerve roots. Herniated disc material (a relatively common process) can put pressure on the S1 nerve root, causing pain along its entire distribution (i.e. the lateral aspect of the lower leg). If enough pressure if placed on the nerve, it may no longer function, causing a loss of the Achilles reflex. In extreme cases, the patient may develop weakness or even complete loss of function of the muscles innervated by the nerve root, a medical emergency mandating surgical decompression. The specific nerve roots that comprise the arcs are listed for each of the major reflexes described below.
A normal response generates an easily observed shortening of the muscle. This, in turn, causes the attached structure to move.
The vigor of contraction is graded on the following scale:
0
No evidence of contraction
1+
Decreased, but still present (hypo-reflexic)
2+
Normal
3+
Super-normal (hyper-reflexic)
4+
Clonus: Repetitive shortening of the muscle after a single stimulation

Technique

The Reflex Hammer

You will need to use a reflex hammer when performing this aspect of the exam. A number of the most commonly used models are pictured below. Regardless of the hammer type, proper technique is critical. The larger hammers have weighted heads, such that if you raise them approximately 10 cm from the target and then release, they will swing into the tendon with adequate force. The smaller hammers should be swung loosely between thumb and forefinger.

1 for turn off and 0 off turn on not need if you turn off your manual lock by going setting.

just use setting to change it, you will able to use 0 again.

You'll need to shim it. Use 35mm film strips, piece of plastic,electrical tape for thicker pad until you can get close to zero with sight set to middle of it's travel.

Rap it on its nose. Us a good screw driver and just give it a tap, not so hard to dent it but a good smack. with the handle. If this does not work remove it smack it, then remount, putting the rings is a small bit different location. 

As a general rule of thumb, If you have normal Weaver-type aluminum rings, you tighten to 10 to 15 inch-pounds. If you have normal Weaver-type steel scope rings, you tighten to 15 to 20 inch-pounds. If it's something exotic and/or expensive, you're pretty much stuck contacting the manufacturer. Leupold Mark 4's require 65 in-lb, for instance.

Wiha makes two adjustable torque screwdrivers (one for lower torque, and one for up to 60 in-lb that are perfect for most any scope ring applications.

Try reversing the rings. Move the back one to the front, and the front one to the back. Turn your elevation adjustment, back to -0-, and start again.

the steering gets easyer as you accelerate is normal when moving slow the weight of the vehical . the rpms are slower makes them feel hard to turn
