56% Stiffer for the SAME Weight

“It is totally dead (….) It is just a straight back push (...) no vibrations.” – Rex Tibor, Precision Rifle Specialist

The following data was collected from an aeronautical engineer using CEL (Combined Eulerian and Lagrangian) to analyze the stiffness of a standard 32 inch .375 barrel to that of a 32 inch .375 Structured Barrel of the same weight. The outer diameter of the Structured Barrel, diameter of the inner tubes, and number of cooling tubes were assumed at 1.95”, 3/8 inches, and 8, respectively.

“This barrel is very different than any other barrel I have shot before. The harmonics and “felt” recoil is not like the impulse from traditional barrels.” – Derek Rodgers, FTR Individual and Team USA World Champion

The following data was collected from an aeronautical engineer using CEL (Combined Eulerian and Lagrangian) to contrast the weight of a standard 32 inch .375 barrel to that of a 32 inch .375 Structured Barrel of the same stiffness.

Harmonically Dead

“They have taken all of the vibration – all of the chatter – out of the barrel.” – Rex Tibor, Precision Rifle Specialist

  • Structured Barrels are known as being harmonically dead
  • Across a wide variety of
  • - Calibers
  • - Munitions
  • - Grain weights
  • Little to no load development
  • Saving you time and money

Harmonic MODES vs NODES

“The rifle itself (...) is much easier [to shoot] with the heavier calibers, because you have good recoil mitigation, and the recoil comes straight back.” - Walter Wilkinson and Tessa Wyrick from Gunsite

  • Structured Barrels are NOT a sleeve
  • Machined from a solid, rifled barrel blank
  • They have a high moment of inertia
  • With a high harmonic MODE and an extremely small harmonic NODE
  • MODES are a function of:
  • - Material stiffness (modules of elasticity)
  • - Mass distribution
  • - Structural stiffness
  • - Determined by testing and analyses
  • NODES are isolated in load development
  • - A derivative of its respective harmonic MODE

No Load Development

“You can run any kind of ammunition in the barrel (...) different kinds of ammo, brands, [and] weights (...) We were running 120s, 130s, and 140s [in a Remington 260 AR-10], and we were (....) putting all the different loads in the same hole – that’s weird.” – Rex Tibor, Precision Rifle Specialist

  • Structured Barrels take advantage of axial compression
  • A physics principle where tubes are always stronger than rods of equal length and mass
  • The Structure pattern makes each hole act like a tube resisting tension / compression forces
  • - As one hole in the pattern begins to "bend"
  • - One side of that hole goes into tension while the other goes into compression
  • - Triggering the opposing hole, opposite of it in the pattern, to undergo compression and tension
  • - 180 degrees out of sync
  • - The opposing forces cancel out making Structured Barrels harmonically dead

+500% Surface Area

“The high rate of fire and impact after impact is proof that this (...) could change the game of precision shooting.” – Derek Rodgers, FTR Individual and Team USA World Champion

  • Structuring turns your barrel into a heat sink
  • Rapidly dissipates heat and does not get hot after multiple, high rate of fire
  • Optimal for PRS, light machine guns, and heavy machine guns
  • Breather ports near the barrel's throat convection and force cools your barrel
  • As each round is shot
  • - Negative pressure is generated by the bullet passing through the muzzle
  • - Pulling cool air through the breather ports and up its neck
  • - Cooling it from the inside

Enhance Barrel Life

“I am most impressed how cool they stay (....) This [Structured] CheyTac after 10 rounds, the hottest we measured, was 86 degrees (....) I think that has a measurable impact on barrel life – keeping it cool. It is a new design, and I know we are all skeptical about changing barrels or believing in new technology, but this one seems legit.” - Cal from Precision Rifle Blog

  • Better control critical thermodynamic transition points
  • Structured Barrels have remarkably less
  • - Throat erosion
  • - Fire cracking (looks like alligator skin)
  • - Gas jetting (deep, irregular lines/groves)
  • Resulting in better accuracy and saving money

Finishes

“The harmonic reverberation that does exist within the system can’t reverberate evenly through it (...) in such a way it cancels it out (....) Harmonics can transfer along the surface very easily; they resonate all the way to one end and come back. If you have interrupted thread pattern you kill the harmonics coming from that avenue.” - Rex Tibor, Precision Rifle Specialist

  • Fallen Angel Pattern
  • - An interrupted series of threads cut in varying lengths, pitches, and directions
  • - Further disrupts harmonic resonance and create a high density fin count to dissipate heat
  • - Harmonics rapidly change with temperature
  • Dimples
  • - Maximum reinforcement around chamber area at minimal weight
  • - Reduces harmonics at that junction when the bullet hits the rifling
  • Sandblast
  • - Increases surface area to dissipate heat
  • - Reduces barrel reflection
