In this video, John Baker breaks down the engineering behind Structured Barrels. This is an 11 min look into the mind and design of new features "to change the concept of what can make an accurate barrel". The first half is about strength and cooling. The second half is all about harmonics.
Thanks for watching!
Structured Barrels are a large diameter, multi-hole hyper rigid barrel that have virtually no barrel whip and are harmonically dead. This is an aftermarket solution that creates a multi-hole ("I-Beam") Structure that both reinforces the main chamber and adds up to 500% more surface area for cooling (depending on selected add-ons).
Structured Barrels take advantage of a physics principle called axial compression enabling operators to shoot sub 3/8 MOA across a wide variety of calibers, munitions, and grain weights with little to no load development, which results in less time and money spent at the range.
Structured Barrels underwent the world’s first structural analysis conducted by Jay, an aeronautical engineer, using CEL (Combined Eulerian and Lagrangian), and found they are 20% Lighter for the SAME Stiffness, 56% Stiffer for the SAME Weight, 38% Lighter for the SAME Frequency, and the data was corroborated by another independent analysis.
Structured Barrels also self-cool from the negative pressure generated by the bullet passing through the muzzle that pulls cool air through breather ports up its neck, cooling it from the inside. To further increases performance, TACOMHQ optionally cuts a dense fin pattern in varying lengths, directions, and pitches with a sandblast finish to add more surface area and deaden surface translated harmonics, making it ideal for PRS, light, and heavy machine guns.
Structured Barrels run cooler so their life is significantly prolonged. By better controlling critical thermodynamic transition points, end users see remarkably less throat erosion, fire cracking, and gas jetting compared to a non-Structured Barrel.
Though TACOMHQ is not in the business of making barrels, they actively work with Bartlein Barrels, Inc, Krieger Barrels, Broughton Rifle Barrels, Pac-Nor Barreling, etc. barrels as long as the rifled blank meets OD requirements: less or equal to .338 must have a 1.75" OD (finished OD is ~1.50") and greater .338 must have a 2.0" OD (finished OD is ~1.90). Cadex Defence, McRees Precision,MDT, Mirage ULR, XLR Industries, and David Tubb ® Adaptive Target Rifle all make compatible chassis.
