 Straight Line Technology and the Accuracy Dream ... come true!

Straight Line Technology  (SLT) simply  stated is a concept that is applied
to all our scopes and mounts from the very beginning of product development
to  the  manufactured  end  result. The Straight Line Technology concept is
strictly followed. The final product is what we call HITECH scopes & mounts.

This  seems  simple enough namely,  take a design concept and apply down to
earth  design  principles  to  it's  development  and  manufacturing.  Then
market  the  product  as  the  best  in  the  world because "down to earth"
design  principles and SLT concepts are applied to it.  And yes this is all
true concerning HITECH  scope & mounts.  But  there  is  more to the HITECH
scope & mount story than this --- much more! 

It all started  back in 1988 when  a design team was formed in Michigan by
Phillip Martel.
In 1988 PC Martel was already  well experienced  in design applications as he  is  the original founder of  D.C. Engineering, Inc. 15
years earlier in 1973. 

The  "PC Dream Team" was formed solely to elaborate  and  put into practice
the  inventive  ideas  and concepts that PC has for firearms. The "PC Dream
Team" incidentally is still in existence today, working together as the top
design  team,  and is truly the back bone of all the HITECH products. 

The PC Martel design team includes a number of Martel family members who's 
experience in design, manufacturing, and  engineering  are truly second to 
none.  The Martel's are considered by many in the industry - as leaders in 
the field! 

Now,  this  brings  us  to  Straight Line Technology (SLT) concerning scope
mounts.  All  original  thinkers  have  a  dream,  and  with  this  in mind
it  was  the Dream Team's goal to design scope mounts using PC's innovative
ideas  as a foundation thus giving birth to the concepts of SLT.  To better
understand SLT,  lets start out by  defining  or going over  a  few   terms
and  definitions  that  will  help  one visualize what SLT is and how it is
applied to HITECH scope mounts.

Straight-line( )adj.   1. composed of straight lines. 2. having the parts 
arranged in a straight line or lines. 3. designating a linkage or similar
device  ( straight-line  motion)  used  to  produce  or  copy  motion  in
straight lines.

technology( ), n.{Gr.technologia, systematic treatment} 1. the science or
study  of  the  practical  or  industrial  arts.   2. the terms used in a
science, art, etc.; technical terminology.

scope rings:
Generally  two  clamping  devices (rings) connected to a "scope" and just
as important connected  to a "rifle base" or rifle.

rifle base:
Generally  a  dovetail  rail  that   is  attached  or  integrated  to  a
firearm  that  serves  for a clamping  connection for the scope rings to
attach to. (i.e. Weaver and Picatinny style rings and bases)

misalignment of rings:
Misalignment  of rings  will  cause  flexing of  the scope during shock,
vibration,  and recoil. Attempts  to control ring alignment can increase
accuracy  but generally requires a great deal of time to correct for the
problem. This  may  include shimming, lapping, and/or  bedding  rings to
achieve  the best accuracy results. A very time consuming project to say
the  least.  Though  once  straightness is accomplished, accuracy can be 
increased dramatically.

misalignment of one piece base or bases:
Without  accurate  base  alignment, accuracy  will  suffer dramatically.
Lateral  alignment  (left and right)  of  the  base/s  should always  be
parallel to  the  center  line  of  the bore of the firearm barrel. Base
alignment as well as machining tolerance is very important.

scope straightness:
If  the  scope body diameter is not perfectly straight, and many of them
are not,  perfectly  aligned  rings  and/or  bases can actually decrease 
accuracy  because  of  the flexing caused by the scope's run-out against 
the "straight" rings and/or base/s  under  shock, vibration, and recoil.
A good analogy to this would be "floating" barrels on rifles to increase
accuracy. Any  flex on the scope like that of a barrel that is flexed by 
it's  gunstock  will  cause  a rifle to shoot inconsistently. We like to
call this phenomenon "torque flexing". HITECH scopes and mounts are  the
"straightest " scopes  and  mounts  you'll most likely  ever buy. HITECH
scopes and mounts eliminate torque flexing by incorporating SLT.

Use your imagination:
Imagine  for  a  moment  that  independent rings were manufactured to be
perfectly straight, perfectly aligned, and perfectly round,(i.e. lapped,
shimmed, and/or  bedded).  How  would  you  know at this point that your
scope and/or base/s are perfectly aligned - having absolutely no run-out 
without spending  an incredible  amount  of time checking with precision
measuring  equipment  that  even  the best of gunsmiths sometimes do not
have? And when gunsmiths have the equipment what about the time involved
to correct the problem. It becomes very costly.

Perplexing alignment and straightness problems:
Once  you  start working in the environment of alignment or straightness 
you  quickly  can see alignment and straightness is a real problem. If a
scope  is  "torque flexed" in  misaligned rings, a flex situation exists 
against the optical line of sight, and accuracy will suffer. And if both 
the  scope  and  the  rings  are  not  straight you will have double the 
trouble  with accuracy.  Add  base misalignment to this equation and you 
have  a  real  mess  on your hands. Between shots, as the rifle comes to
rest  under  shock,  recoil, and vibration the optical center will relax
into  yet  another  position and the "line of sight" will change and the
next shot will be out!

In testing,  a riflescope only needs to move one thousandth of an inch at
any time on the rifle, (about 1/3 the thickness of a human hair) - to put
the  next  shot  fired out of accuracy by one full inch from the previous 
hit at 100 yards/meters.

SLT (Straight Line Technology) solves the problem:
SLT  solves  all  of the  problems concerning alignment and straightness. 
SLT solves  the  problem  by  simply  taking into account that nothing is
perfectly  straight  and  that  alignment  is  never  totally correct and 
compensates for it.  Thus, "pulling" to  all centers no matter where they
may  fall  in  a world that is not perfectly straight must be the answer! 
The fundamentals of SLT are exact - true in theory - true in practice.

Astonishing Results:
When SLT  is  put  into  action the results are simply astonishing! Unlike 
independent  rings  or  rings that are horizontally split (cap type rings) 
all HITECH  scope  mounts  incorporate  SLT  and are vertically split  and 
integrally  bridged from front to back to allow for simultaneous alignment
evenly  across the mount's length thus "pulling' to the true center of the 
scope, and the true center of the base. This patented design really works!
Add  the  optional quick disconnect feature which is also patented and the
fastest  in the world and you are prepared for ultimate speed and ultimate
accuracy.

Two of the most important benefits of using this innovative design are as
follows:

Benefit #1:
In  testing  our HITECH mounts we found immediately that shimming, bedding, 
and  lapping  was  totally unnecessary and that in all instances on scopes 
"right straight out of the box" were already "on paper" at 100yards/meters.
(See foot notes concerning testing) 

Benefit #2:
Accuracy tests were extremely amazing. Firearms in  testing that could not
hold  tight  groups using other brand named equipment literally shot twice 
as tight and more using HITECH mounts! The accuracy results in our testing 
was incredible. SLT pays off in a big way! 
 

foot notes concerning testing:
All  rifle  scopes  available in today's market place are typically set to 
optical neutral at the factory. This simply means that the central portion
on  the  cross  hairs  (center point)  are  very close optically to a dead
center  relationship  to  the scopes inner or outer body. This dead center
position  is  adjusted  by  moving turret screws in or  out which controls
windage and elevation settings. (i.e. 1/4 inch clicks.) 

In numerous tests we found that our HITECH mounts were near dead on bull's-
eye at a  100 yards/meters  without even touching the scope's adjustments.
This is  an  amazing  result to think that only minor adjustments from the
factory set to "neutral" position is even necessary!

In a large percentage of tests on various rifles, including the  AR15 flat 
top,  hit  points were within 1 inch of dead center,  without readjusting
windage or elevation settings from the factory neutral setting. 

In  testing handle model AR15's the same results were achieved by a slight
"down hill" adjustment of our HITECH base.  (Worlds  first adjustable base 
for  elevation (up or down)  using no special tools or shims  and  is self 
adjusting  for lateral alignment.)  The  HITECH  base and it's applications
are patented. 

Accuracy tests  were  also  extremely  amazing. Firearms that could not in 
prior test shoot tight groups  literally  grouped more than twice as tight 
and more! The  accuracy  results  in  our testing  have  been  incredible. 
Through  the  same  hole  shots  are  an every day occurrence using HITECH
scopes and mounts.

HITECH scopes and mounts are a design and engineering dream come true!:
After  thousands of hours of design, testing, development and a number of 
U.S. Patents  later,  HITECH   scopes and mounts  incorporating SLT,  are 
truly what the "accuracy dream" is all about! We invite you to be part of
the HITECH excitement and experience the accuracy dream yourself! 
 

Special foot note to our U.S. Military friends: 
In testing,  addition  accuracy  was  increased using our HITECH under rail 
on the  detachable  handle  as used  on the flat top.     ( 1/16 of an inch 
better groups using the  detachable  handle  than  without!) This certainly 
defeats the common reason  for  using  the flat top design. But when tested
on non-detachable handle model AR15's accuracy decreased significantly more
even though this flat top accuracy was greater with our equipment than with
any and all others tested.  

Analysis in brief:
After analyzing  the data  we found  that the detachable handle and the flat
top upper receiver has much more aluminum material (producing less harmonics 
and  vibration  under recoil) in areas than the non-detachable counter-part. 
This  increase in strength  on the flat top handle and on the flat top upper 
receiver increases accuracy using our HITECH under rail patented design. 

Though the increase  was  marginal, accuracy was approximately  1/16  of an 
inch  greater  on  3  shot  groups  at  100  meters  than mounting  optical
sighting devices  directly to the  Picatinny flat top.  For a more detailed 
explanation  of  this  testing  and  results contact Phil or Timothy Martel
in care of
the company or Engineering at the same.
