Q: How much shim should I use for proper bullet information impact?

A: Your firearm may be adjusted for point of aim at almost any reasonable handgun distance.  Our experience has been, as a starting point for sight elevation for 25 to 50 yards, that about half a shim is needed with most Glocks of 9mm and 40 calibers.  With the Glock 20 you might want to start with about 1/4th of a shim to no shim at all. With Springfield XD pistols you may want to start with half a shim for all calibers.  Each whole shim is 30 thousandths of an inch and is assembled in two thousands of an inch laminated sheets.  Place the shim in a vice and peel off the amount of thickness needed with a thin bladed tool.  The amount of shim needed, especially as distance increases, will vary from individual shooter, individual gun and barrel, and the load being used.  Sometime in the future our shims will come pre-separated in different thicknesses.

Q: Do you have any additional tips for rear sight installation?

A: We always recommend the use of a licensed gunsmith for sight installation. Make sure your firearm is unloaded before starting any procedure.  Remove the slide from the frame before starting any sight changes with your firearm.  Remove the factory rear sight.  Remove or loosen the locking screw on the ATS rear sight almost to point of removal (the lock screw must be almost all the way out to ensure smooth installation) before installation or removal of the ATS rear sight.  A sight-pushing tool is the most efficient way to drift the rear sight into place or adjust it for windage.  Some have had success tapping the ATS rear sight into place with a wooden or plastic (no metal hammers) mallet.  It is advisable to put a tiny amount of grease in the rear dovetail before installing the ATS rear sight.  Once your windage adjustment has been established, tighten the rear sight lock screw.  This will protect your settings in extreme situations.

Q: When will the ATS be available for my particular handgun?

A: We will eventually offer the ATS for all popular handguns, shotguns, and carbines.  Check with the production update page for the latest in news about the ATS and sight availability.  We currently have sights for Glock pistols and Springfield XD pistols.  Other applications will soon follow, according to demand.

Q: Are you planning to have night sights?

A: Yes, we have new technology that will revolutionize the night sight industry.  This new technology will be announced on our product update page when our patents have been filed.  Our ATS night sights will correct the problems associated with tritium based and glow crystal injected sights.

Q: How is the best way to change the colors inserts on the front sight?

A: First, make sure you are using the proper punch size.  A 1/32 punch or a #66 drill blank are appropriate.  With an unloaded firearm remove the slide from the frame.  With the muzzle end of the frame pointed forward punch the pin half way out from left to right and then remove it with a needle nose pliers.  Peel off the current insert and press in the desired insert.  Before pin reinsertion, make sure the holes in the insert and the side holes of the insert base (the front sight) are aligned.  Hold the newly seated inset in its base up to the light to check for proper hole alignment.  Then, apply pressure to the insert with your thumb while tapping the pin in place.  Your thumb pressure will ensure continued alignment through the pin insertion process.

Q: Will there be additional colors, other than the current five now being offered?

A: Yes, we will have others.  Eventually, we will have blue and black inserts.  Others will be considered upon request and customer demand.

Q: Do we get all five colors with each sight set or do we have to specify a color preference?

A: Each sight set includes all five colors.  You may switch them around to create 25 different front and rear sight color combinations.

Q: When you say that your sights are not “night sights” but they can be seen in subdued light, what does that mean?

A: The ATS is a big sight.  The rear sight expands almost the entire girth of the slide.  The colored inserts are also big and highly fluorescent.  The large fluorescent colored inserts are very sensitive to ambient light.  They operate in a zone where the ambient light does not allow a clear view with regular sights, including those with fiber optics or tritium inserts.  Fiber optics need a light source to appear brilliant and tritium inserts are in their most active bright state in very darkened situations.  Most tactical situations occur in dim light when a sight picture can be compromised by the lack of available light.  An unclear sight picture impedes quick target acquisition.  “Night sights” that can be seen in darkness are certainly valuable in limited situations and Wrentech will be introducing a night sight version of the ATS in the future.

Q: When you align the front and rear sights with the ATS, what part of the sight do you use for bullet impact?

A: The front and rear sights are a visual two-piece jigsaw puzzle.  When the front and rear sights are aligned they create a pyramid-like configuration.  The top, the point of the pyramid, is where bullet impact will occur.  The dimensions of the ATS were carefully engineered to allow quick sight acquisition of the target without compromising accuracy.

Q: What about the usage of tactical lights or flashlights with you sight?

A: We have found it most effective to use a tactical light with our sight much like a photographer uses bounce flash.  A tactical light pointed up at even a high ceiling will be more than enough to illuminate our highly ambient light sensitive colored inserts as well as the target.  This type of tactical usage allows a police officer or home defender to focus on his or her sights and target and not be preoccupied with the direction of the tactical beam during tactical situations.
