What is Cryo-Accurizing? |
Cryo-Accurizing relieves stress in firearm barrels through deep cryogenic
tempering. Stresses cause a barrel to bend or warp as it heats from repeated firing
-- warping causes walking, stringing or wandering in the shot group. Deep cryogenic
tempering process relieves internal stress in the firearm so the barrel will no longer
bend or warp. In addition, your firearm will be easier to clean and give you
increased performance, increased accuracy and extended barrel life. |
The
Process |
Deep cryogenic tempering is a one-time, computer-controlled process where
metal is cooled slowly to deep cryogenic temperatures (-300 F), and slowly returned to
room temperature. The metal is triple-tempered as the final step in the process. This dry
process permanently refines the grain structure of a firearm barrel at the atomic level,
producing a homogeneously stabilized barrel. The denser, smoother surface reduces
friction, heat and wear. The result is better shot groups in handguns and rifles and more
consistent coverage and placement of shotgun patterns. Your barrel will last longer, be
stronger, shoot better and be easier to clean! |
Who's
Using Cryo-Accurizing? |
J.P. Enterprises, has a
reputation for cutting edge AR15 rifles, components and custom bolt guns. This is what
John Paul says about cryogenic tempering: "Having
all our barrels treated by Diversified Cryogenics allows us to produce complete rifles and
component barrels that consistently reproducible accuracy coupled with outstanding barrel
life. Since we started treating all barrels, we have not had to replace a barrel for an
accuracy problem. Customer feedback has been excellent."
John Russell,
hunter/shooter-gunsmith. He shared personal Chronographic test results that
document increased bullet velocity after Cryo-Accurizing his rifle. The rifle: Mauser
98 actions with a .243 Winchester barrel. The handload: 75 grain hollow
point bullet with 36.9 grains of IMR 3031 powder.

Russell's comment:
"The numbers show how well it works. I gained 50 feet per second after the rifle
was Cryo-Accurized." |
And
there's More... |
Randy Luth of DPMS, an AR15
rifle manufacturing company had this to say about Cryo-Accurizing: "One of the truths about rifles and
guns is their erratic shooting after heating up. The Cryo-Accurizing process remedies
this. Now I find that my impact point stays the same from the first shot to the 100th
shot."
"We make the Cryo-Accurizing process
an option for customers when ordering their rifle - and all our orders are processed by
Diversified Cryogenics. We added the Cryo-Accurizing option for customers because the the
word spread regarding the benefits of the treatment, customer demand grew. From what our
customers have said, and from what we've seen, there is no doubt that cryogenic treatment
increases the wear life of the barrel and makes cleaning easier and faster." |

Why
it's Needed |
All firearms develop mechanical and
residual stresses during manufacturing, even with the most careful processes. These
stresses cause twisting and arcing as the barrel heats up from repeated firing.
Cryo-Accurizing permanently relieves the internal stresses with no risk of damage to the
barrel or the action of a fine gun. |
Frequently
Asked Questions |
What is the turnaround time?
Five to seven days.Can I send my barrel with the receiver?
YES - you can send only the barrel or the barrel with the receiver. Barrels with
receivers cost $10 more. The receiver must be stripped, with no bolt or trigger mechanism.
Does the process help stainless steel barrels as well as Blue (chrome moly)?
YES - deep cryogenic tempering will relieve stress in almost all types of steel.
Does the tempering process affect the cleaning of the barrel?
YES - shooters have reported that their barrels clean much easier. They also say
muzzle velocity increases 50-60 feet per second.
Should I treat the blank or the finished barrel?
Both can be treated for different reasons. The blank or round is treated for the benefit
of the gunsmith because it improves the machinability and dimensional stability. Shooters
benefit because tempered barrels shoot straighter and last longer.
Will cryogenic tempering affect the barrel finish?
No - the process will not affect the barrel finish whether it is Blue, Parkerized
or Teflon.
Is the stress relief permanent?
YES - the stress relief is a permanent one-time, irreversible process.
What are the risks of damage?
There is no risk of damage to the barrel or the action of a fine gun. Our
computer controlled process is completely dry, eliminating any chance of thermal shock or
micro-cracking. Your barrel is handled with painstaking care using our exclusive cotton
glove treatment. |
