Question about The Optics

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

Spray it with a dry silicone spray like Jigaloo. Put a very small amount on the underside to test as it can sometimes damage plastic. It is a great product though.

That should be covered in your manual.

If not, give Nikon a call.

Or, repost your question on a Bulletin Borad such as at SWFA, where another user may have the identical scope.

If you are attempting to use a red laser in daylight, you have to wear special glasses to see it well. You may have to complete this project with less light, such as after dark, or indoors. Only green lasers will show up in daylight. If this is not helpful, then I suggest that you change the batteries to brand new ones that you are sure of. There is probably no adjustment possible. Best wishes for your safe shooting!

SOURCE: older hunter original, needs lubrication.


This is the owner's manual to your fan

As for oil, you can use one of two oils. Depending on how old your fan is, I suggest changing the oil by removing the fan, turning the motor completely over and letting it drain into the "dish" on the part that spins, clean the oil out of there, then re-hang the fan and oil with 1 oz of either Hunter Fan Oil (which is available from hunter, or on ebay, just search for Hunter Original Fan) or Zoom Spout Oiler, both are the same oil.

What part of the brain test rapid reflexes

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:
No evidence of contraction
Decreased, but still present (hypo-reflexic)
Super-normal (hyper-reflexic)
Clonus: Repetitive shortening of the muscle after a single stimulation
For more information about anatomy and physiology of reflexes, see the following link:

Washington University Review of Anatomy and Physiology of Reflexes


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.

Why does my manual adjustment need to be on ''1'' to turn off? It was ''0''

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

Shoots realy low cant get it to raise enough

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.

Bushnell Trophy scope on BLR .308 -- was fine when last used but now shoots 4 ft high at 100 yards and elevation screw is maxed out -- doesn't seem to have moved in rings and no visible sign of damage --

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.

Overtighten causes hazing,and adjusment problem

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.

Cannot sight in riflescope for elevation, adjustment is maxed out

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.
