Our Suppressors

All ECCO Machine suppressors are made in Elizabeth, CO USA from certified Aerospace materials machined to precise tolerances on CNC turning and machining centers, then each one is hand fitted and finished to ensure the highest possible quality. We use Norrell’s Moly Resin enamel, a very durable high temperature baked-on finish that will last through years of use:

www.molyresin.com

With tube type suppressors, we run snug fits with baffle stacks. As such, tolerances in the manufacture of the CWSR tube sometimes mean we have to lightly sand the exterior of the baffle stack for a smooth fit. This will result in some baffles having a shiny stainless exterior finish that does not match the gold-bronze color shown in stock photos. This does not reduce the strength at all, is done just to knock down the tips of the indexing tabs that expand slightly when clicked into the notches of the baffle in front of it, sometimes making them a little too tight in the tube.

Accipiter

Accipiter is our flagship rifle model, built to handle all the things! Constructed entirely of 17-4 H900 stainless steel, the fusion TIG welded tubeless design features our unique baffle arrangement and carefully developed mating surfaces for extreme strength and excellent suppression of high velocity rifle rounds, up to and including the Remington Ultra Mags and .338 Lapua magnum. It’s also a solid performer with subsonic rounds, though it was not optimized for them.

The standard configuration for Accipiter is with industry standard 1.375-24 Bravo (“HUB”) pattern threads to make it compatible with your favorite mounting system adapter or direct thread mounts.

ECCO Machine rifle suppressors are offered with no mount for those who wish to run a mounting system other than direct thread or our Helix Port (Patent pending) taper mount muzzle brakes. We feel that there is no need for our customers to be paying for an included mount that they do not need or want. Our Direct thread mounts or taper mount adapters and brakes can, however, be packaged with a suppressor purchase at a lower price point than when purchased individually.

Aquilae

Aquilae is Accipiter’s truncated brother. Constructed entirely of 17-4 H900 stainless steel, the fusion TIG welded tubeless design features our unique baffle arrangement and carefully developed mating surfaces for high strength and impressive suppression of high velocity rifle rounds, up to and including cartridges like the .300 Winchester Magnum and .375 H&H Magnum. Though not optimized for subsonic rounds, it also performs quite well with them.

Valkyrie

Valkyrie is a slightly trimmer version of Aquilae and Accipiter. Boasting the same fusion TIG welded tubeless 17-4 H900 stainless steel construction and baffle technology, it gives up little in suppression compared to it’s “chubbier” bretheren, and is rated for cartridges like the .300 Winchester Magnum and .375 H&H Magnum.

Why make a .1″ narrower can? Well, some people just like 1.5″ diameter, and some handguards won’t take a 1.6″ suppressor for those who want to tuck them.

The standard configuration for Accipiter is with industry standard 1.375-24 Bravo (“HUB”) pattern threads to make it compatible with your favorite mounting system adapter or direct thread mounts.

Furtivus

Furtivus is the skinny kid! At 1.37″ outside diameter, it’s a slimline can, but the fusion TIG welded tubeless 17-4 H900 stainless construction still allows internal volume on par with 1.5″ diameter tube type suppressors. With the same highly developed baffle profile, spacing and mating surfaces as the larger suppressors, it’s still extremely tough and very effective, while saving a little weight and looking less disproportionate on skinny sporter barrels. Designed with the hunter in mind, Furtivus is still perfectly capable of taking the heavier firing schedules of range days with semi auto rifles. Like it’s heftier counterparts, Furtivus does well with subsonic rounds but really shines with high velocity cartridges.

The standard configuration for Furtivus is with 1.125-28 Alpha pattern threads to make it compatible with several popular mounting system adapters and direct thread mounts.

Caliber: .22 to .45, .30 standard

Five By Five

Developed specifically for short barreled 5.56mm rifles, Five By Five gets it’s name from it’s 5″ long, five baffle design. Featuring our unique progressive baffle profile, Five By Five is able to offer truly astounding suppression from such a small can, coming in right at 140 dB at shooter’s ear on a B&K Pulse system when fired from a gas adjusted 10.5″ AR-15 using ball ammunition. It was carefully developed to balance back pressure with muzzle end suppression on these short barreled semi automatic host weapons, and we are truly proud of the end result.

Phantom 8

Built for the hunter on the move, Phantom 8 is an extremely light weight suppressor meant for full power high velocity rifle rounds. It’s ultralight construction does limit it’s ability to handle volume of fire, but for it’s intended purpose, that’s not a problem!

As a hunter myself, I have used this can on my .25-06 to harvest many big game animals, and it still amuses me to watch their confusion when all they really hear is the sonic crack and just can’t figure out where the noise came from!

Susurrus CF Integral Rifle Suppressor

Caliber: .22-.45

Suppression: 35+ dBA

Length: Variable

Made from titanium and 17-4 stainless steel, the Susurrus CF series are lightweight custom integral rifle suppressors that can be fitted to many hosts in many calibers. Real-world suppression is highly dependent on particulars of the suppressor and host; 6.5 Creedmoor, 7mm-08 and .308 rifles with 16″-18″ barrels typically meter in the low 120s dB range at shooter’s ear with full power ammunition. These integrals would normally be built to have an effective barrel length (barrel + suppressor) of 25″-28″ for high velocity cartridges.

Susurrus can be made to work with nearly any cartridge, but is ideal with intermediate and .308 class rounds for minimal velocity loss with the relatively short and heavily ported barrels. Very high velocity and magnum rifle cartridges need longer barrels to realize their potential, so the overall length of an integrally suppressed weapon chambered in rounds like .22-250, .25-06, .300 Win mag, etc. will become significant.

Weight, length and cost are highly variable, depending on what we’re working with, how we’re building it and if we’re doing all fitment & inletting here, if you’re working with another smith, or doing some of it yourself.

The construction of Susurrus is not conducive to making “one-stamp” guns with barrels under 16″, so shorter builds really need to be done with SBRs.

Price: From $1,199

Phoenix M

The modular Phoenix M suppressor is a handgun suppressor that is also capable of handling limited use with intermediate rifle rounds due to it’s very tough stainless steel and titanium construction. Though we do not approve it for this use, it has actually been tested on a fully automatic .308 with a 13 inch barrel.

With 14 (yes, 14!) baffles in it’s full configuration, it offers incredible suppression, but you still have the option to run a shorter 10-baffle configuration when portability/handiness is more important than maximum suppression.

The internal booster is compatible with SilencerCo/Rugged style pistons, including Griffin Cam Lok, and the booster housing is threaded 1.125-28 to accept your favorite Alpha pattern adapter or direct thread mount.
Full length standard pistons protrude 1/4″ from the retainer to ensure guide rod clearance with your hosts.

Phoenix IX 9mm Pistol Suppressor

The slender Phoenix IX suppressor is a 9mm handgun suppressor that offers impressive suppression in a lightweight can that is less obtrusive to your pistol’s sights than common 1-3/8″ diameter cans.

Canine

Canine is an ultralight special purpose suppressor that was developed for applications where length and weight are the priority, such as concealement.

Ocelot Micro .22 Rimfire suppressor

Dynamite comes in small packages! Except in this case, it’s the opposite! Trite proverbs aside, the Ocelot Micro truly is amazing for it’s size. Tiny cans like this do have a pronounced first round pop when run dry on pistols, no getting around that, but it settles right in on the follow ups, offering performance one would expect of a considerably larger suppressor. On a rifle, you’ll be hard pressed to tell the difference between Ocelot Micro and most full size rimfire cans. A great deal of time was spent developing it, and we’re really proud of this one!

Salamander

Salamander is the long awaited solution for tube magazine fed rimfire rifles and pistols with low sights!

At just 3/4″ diameter, the Salamander allows tube fed rifles to be reloaded without removing the suppressor, as well as being able to use the small, low sights on pistols such as the Beretta model 71 which are obscured by typical 1″ diameter suppressors.

Despite it’s tiny size and scant 2.5 ounce weight, the Salamander provides impressive suppression, coming in at 118-119 dB on a 16″ Bolt action rifle and 122-124 dB on a semi automatic handgun firing subsonic ammunition (measured at shooter’s ear).

Salamander is a user serviceable suppressor made entirely of titanium and 17-4 H900 stainless steel, so cleaning is a snap using your favorite ultrasonic cleaner or harsh solvents that would attack a can with aluminum parts.
