Octave-12 Shotgun Suppressor

There's a quiet little battle in the tactical shotgun world among three modern takes on the pump-action design, and UTAS has made a soft step ahead of the pack with the introduction of it's new shotgun suppressor, the Octave-12.

We gave you a look in October at the UTAS UTS-15 pump gun that holds 14+1 rounds in two tubular magazines. It's competing in the market against two other high-capacity pumps, the KSG and the DP-12. Now UTAS is branching out and taking on SilencerCo's Salvo 12 shotgun suppressor, the most successful 12 gauge suppressor available.

At last year's SHOT Show Media Day at the Range, I and a number of writers got a chance to shoot the DP-12 for the first time, but we also got to try out a prototype of the UTAS shotgun suppressor mounted on a UTS-15 at the skeet range of the Boulder Rifle and Pistol Club in Nevada.

The prototype shot great and didn't hamper me from taking 13 out of 15 clays, without reloading. (Anyone who knows me will tell you that's an incredible achievement for any shotgun in my hands.) The shroud on the prototype was made of aluminum.

"We decided to go totally with carbon fiber due to weight and strength," said Utas-USA CEO Ted Hatfield in an email today.

Mounting adapters are available for Beretta/Benelli, Win Choke, and Rem Choke systems and the suppressor has been approved for lead loads including buckshot, birdshot, and slugs, making it a definite contender as a hunting can.

The Octave, which can run wet or dry, uses a unique material to absorb sound and heat.

"The greatest difference (between the Octave and other shotgun suppressors) is that it utilizes sound dampening packing material. The packing material is volcanic rock that is spun into a fluffy material like cotton candy, which is then formed into specially constructed cylinders around coarse mesh stainless steel tubes that keep the packing material from migrating into the bore," Hatfield said. "The (material) will withstand temperatures beyond 2,000 degrees Fahrenheit and dampen sound like sticking a firecracker in a pillow."

A prototype of the Octave was available for members of the media to shoot at SHOT Show 2015. The shroud on the prototype was made from aluminum, whereas the shroud on the final model is fully carbon fiber to save on weight.

Why are there so few shotgun suppressors on the market compared to those made for rifles and pistols? They're a bit more complicated than your average can.

"While both pistols and rifles have a single projectile, a shotgun has at least two—the wad or plastic shot cup and a slug or loose shot. Rifles and pistols can utilize openly spaced baffles or wipes to shear off and dissipate gas. The configuration of shotshell projectiles require some kind of enclosure to keep the plastic wad cup from opening until it leaves the muzzle of the suppressor," Hatfield explains. "The Octave-12 utilizes a skeletonized bore-diameter tube to hold the plastic shot cup in place,while allowing rapid gas dispersion. Additionally, a baffle divides the Octave-12 into two expansion chambers."

The components are all shrouded in a woven carbon-fiber sheath that adds strength and heat dissipation while keeping it lightweight.

The suppressor produces a noise reduction of -20 decibels, depending on load, barrel length, and conditions. The company is currently seeking qualified, licensed dealers.
