I know that you gents from TNVC recommend a 12 o'clock mount over a 3 or 9 o'clock mount. The idea being that a 12 o'clock mount doesn't have windage issue.

That being said, even if the laser is mounted at the 12 o'clock, wouldn't one still have the problem of both windage and elevation error, as the laser is offset from the bore-line to clear the front sight base? Obviously, if the laser were centered over the bore, this wouldn't be the case.

Or am I just missing something important here?

Some of us are advocates of the 12 o'clock mounting and, you aren't missing anything.  On a DBAL, the laser is offset from the bore and, you do have windage and elevation offsets.  If you want to have a laser that centers things up, check out the ITAL.  It will brings things into line on one axis, leaving you to deal with only one offset.  However, when you start considering how you are zeroing, in comparison to your bore/ day optic relationship...then, you deal with offsets as well.  Best thing is to find a setup that works for you.  Know your offsets, and become a competent shooter by utilizing it at different ranges and learning your holds.

Sorry for the delay in response.  We have been super busy with training, testing and business.  If you need a quicker response, give us a call or shoot us an email.  

Stay Safe.

No it doesn't, Sam.  Read it again and get the small, brown, naked boy's hair out of your eyes.  They are an two different subjects.  The newsletter addresses rear mounting (which you are familiar with) and forward mounting of the DBAL in the 12 o'clock position.

Stay off the khat and , be safe.

See you back in the world.

Ok fair enough this is what happens when you haven't slept in 48 hours and you have a brain shart. I'll be backin 3.5 months, you should really make more of an effort to drink with me, got some interesting stuff happening at Tellgru hope you can help us with a few things, looking forward to the TV series.

I'm about to order a civilian DBAL.
Somehow I was dropped from  the newsletter  list a while back.
Anyplace where I can find the info regarding forward vs rear mounting of the DBAL?

Or can you give me a synopsis ?



Thanks!

Here's a cut and paste from the Newsletter:

Where does that laser go?    
by: Kyle
We get a lot of questions about where you should mount an Infrared Laser on your gun.  There has been a modern trend to want to move the laser back towards the receiver to eliminate some of the weight from the forward part of the gun.  This move, provides better balance and removes some of the clutter from the front of the rifle.  While we appreciate the spirit of this move, there are some points of caution that you must consider:

1.Modern aiming laser/ illuminators, like the LDI DBAL, fit relatively low on the rail.  They are designed that way so they are less obtrusive and, do not provide sight block when they are mounted in the 12 o'clock position.  Because of this, when you mount them back towards the receiver, you take a chance that your shooting hand or your other accessories may block the emission.  With the modern trend being to shoot with an "over-wrap" grip, this can become even more pronounced.  You obviously don't want to break your normal handgrip, just to shoot at night so, caution should be taken when you set-up your rifle.
2.The rearward mounting position can sometimes interfere with  the operation of your light and laser, simultaneously.  One answer, is to go to a dual tape switch that will operate both.  SureFire makes a fine example of this, as does L3/ Insight for those of you utilizing the PEQ-15.  Depending on how far apart the two accessories are and, the length of the cables on your switch, will determine where you can mount your switch.  Again, during setup, ensure that the switch is placed where your hand is accustomed to gripping the rifle.  
3.Last thing is; for our Military clients out there, you understand the critical error that can be made from mistaking the emission point, for the "splash/ sparkle".  Because of this, it is a critical point that there be nothing in front of the laser, thus eliminating the chance that an Operator could "lase" themselves.  For the Civilian shooters out there, this may not seem like such a critical point.  While you are correct that it may not return gunfire or CAS on your location, it may provide enough reflection to disrupt your view of your target or quarry an make you miss your shot.  So, still important.

In closing, we always like to look at the new tips and techniques that are out there.  We set things up, we analyze and we try to provide a humble but useful  take on what we find.  We feel like the rear-mounting trend has some merit.  As always, if you take a look at your mission, take the time to set things up to work correctly, you will always be able to tweak your gear to get you to that next level.  Have fun, shoot straight and Stay Safe.
