We tested the Dead Air CT5P 5.56 NATO silencer with a Sig Sauer MCX Virtus in 5.56.
The result? A soft-shooting, hard-use, pleasure-to-shoot rifle for defense professionals and civilians alike.
The Dead Air CT5P Patrol Silencer is designed to complement Law Enforcement patrol rifles. Where once scary black guns were anathema to local Law Enforcement, now they are absolutely everywhere.
The CT5P is specifically intended to enhance the performance of these ubiquitous weapons.
The CT5P Patrol is an exceptionally lightweight, low-backpressure can that offers amazing performance in a delightfully compact package.
Why We Combined the CT5P Patrol with the SIG MCX Virtus
The same attributes that make the CT5P Patrol so effective for law enforcement also make it the perfect can for the defense-minded responsible civilian shooter as well.
A suppressor this awesome demands a pretty rarefied host. We settled on the Sig Sauer MCX Virtus.
Orbiting around the same apparently perfect short-stroke piston-driven action that drives the Army’s new M7 Spear battle rifle, the MCX Virtus runs clean and shoots true.
The MCX Virtus really is the optimized patrol rifle. Featuring oversized controls, optimized human engineering and next level reliability, the MCX Virtus is the ultimate evolution of Gene Stoner’s apparently unkillable combat weapon.
Amidst a sea of modern sporting rifles cluttering up your local gun emporium, this really is as good as it gets.
No Better Time To Buy A Suppressor
We are on the leading edge of a sea change in the American gun world. After 92 years of artificially constraining our 2d Amendment rights to own sound suppressors and short-barreled weapons, the leash is slowly coming off.
American industry has responded predictably and well.
Thanks to the passage of the Big Beautiful Bill, the draconian transfer tax on all NFA items save machineguns and destructive devices has been administratively reduced from $200 to zero.
Serious patriots are hopeful that the entire registration scheme will eventually go away as well. As a result, sound suppressors have catapulted from the shadows right into the mainstream.
In late 2025, there were around five million sound suppressors in the NFRTR (National Firearms Registry and Transfer Record).
Up until the end of the year, the BATF processed an average of 2,500 transfer forms per day. In the first 24 hours of 2026, they accepted 150,000 new Form 4’s.
Where once these things were exotic and rare, nowadays, sound suppressors are absolutely everywhere. The CT5P Patrol is the everyman can.

The CT5P Patrol's Philosophy of Stealth
No kidding, if you haven’t had the pleasure, this suppressor will absolutely ruin you to conventional guns. Once you have run a rifle with this can in place, you will never go back.
The CT5P Patrol excises the nasty from a gunshot so you can retain your capacity to communicate and employ your weapon both more safely and more efficiently.
There are substantive parallels between the typical street cop’s patrol rifle and the responsible citizen’s home defense iron.
Both weapons need to be maneuverable, reliable, and carry plenty of downrange horsepower. They should to be able to sit about unmolested for years if necessary before being called upon to make that one critical shot.
The synergistic combination of the SIG MCX Virtus rifle and the Dead Air CT5P Patrol suppressor checks all of those blocks.
CT5P Silencer Details
The CT5P Patrol is designed to balance high performance against weight and compact dimensions.
It builds upon the lessons learned from the Lazarus 6 and Sandman X cans, both staples in the Dead Air pantheon.
Mounting the CT5P 5.56 Silencer
Part of the equation has been simplifying the mounting system.
Back when we had to pay $200 just for the privilege of owning one of these things, it made sense to incorporate versatile mounting geometry so that one suppressor could be readily swapped among multiple hosts.
Now that the process is more affordable, Dead Air offers a fixed direct 1/2x28 thread mount to minimize both weight and point of impact shift.
To mount up the Dead Air CT5P, you just twist off your flash suppressor, thread on the can, and hit the range. For detailed instructions on mounting the Dead Air CT5P silencer and maintenance tips, consult the owner's manual.
Why It Works
This Dead Air can orbits around a compact version of their superlative Triskelion baffle system.
This patent-pending baffle design coupled with Dead Air’s Gas Management System minimizes backpressure while diverting a great deal of the nasty fumes out of the shooter’s face.
In so doing, it also results in minimal changes to bolt velocity in Stoner-inspired direct gas impingement operating systems.
What It Does
The end result reduces the battering on your ears, minimizes concussion and overpressure, particularly indoors, and helps keep you alive when things goes all pear-shaped.
The secret to the effectiveness, efficiency, and durability of this suppressor is additive manufacturing using Haynes 282 substrate.
Haynes 282 is a premium gamma-prime strengthened nickel-based superalloy engineered for extreme high-temperature structural applications.
How It's Made
This amazing stuff offers exceptional creep strength, thermal stability, and superior weldability/fabricability in a material that isn’t just stupid expensive. It also lends itself to metallic 3D printing.
By 3D printing the CT5P Patrol out of this super-material, Dead Air combines unparalleled strength and longevity with the sort of complex internal geometry necessary to accomplish such rarefied performance.
An economy of scale keeps the price in check. The CT5P Patrol is the ideal grab-and-go unkillable rifle can.
Sig Sauer MCX Rifle Details
Sig Sauer. Wow. Those guys do it up right. Never before in history has a single company earned the contract to supply the US military with its service rifle, combat handgun, and light machine gun, yet here we are.
In addition to producing the finest firearms on Planet Earth, SIG also willingly offers their wares to us lowly civilian shooters as well.

Sig Sauer MCX Virtus DNA
The MCX Virtus is the predecessor to the subsequent MCX-SPEAR-LT. Both weapons share a common DNA.
Everything about this rifle is optimized for hard service in the real world. The adjustable short-stroke gas piston operating system runs clean and cool.
The design keeps crud out of the receiver and away from the multiplicitous moving parts of the gun.
The Sum of Its Parts
The cold hammer forged steel barrel features a tight 1-in-7 twist to stabilize most any imaginable bullet weight.
The muzzle is threaded 1/2x28 and features a tapered shoulder specifically to accommodate a sound suppressor.
The safety is perfectly replicated on both sides of the gun, so it really doesn’t much care which hand you favor.
MCX Rifle Ergonomics
The minimalist buttstock both folds and collapses. The pistol grip sports an oblique angle to help keep that strong side elbow tucked in tight as it should be, and the trigger comportment flirts with divine.
Lots of folks hit around the idea of building the perfect AR15. SIG has pulled it off. This thing is as smooth as Marilyn Monroe’s nylons and as rugged as John Wayne’s jockstrap. This is the gun upon which you might freely bet your life.

EOTech Optics Sighting Solutions
A rig this awesome warrants some proper tactical glass. We opted for a time-tested EOTech EXPS Holosight equipped with an armored G33 magnifier.
The EXPS actually projects a holographic sighting reticle onto your retina. This causes the image to seem to float out above your target regardless of the distance.
That’s just weird enough to be awesome. The G33 magnifier offers 3X magnification and slaps out of the way instantly when not needed. The combination is military tough and nigh unkillable.
The end result flirts with perfect. You will fail before this gun does. Running the MCX demands the same familiar manual of arms as any typical AR15. The rarefied particulars mean it is faster than most, however.
The wide field of view and holographic reticle afforded by the EXPS mean optimize situational awareness starting at bad breath range.
The magnifier lets you run the gun accurately out to the limits of the cartridge. EOTech has been a major supplier of military gunsights for decades. Their reputation is peerless.

The CT5P Patrol suppressor transforms the shooting experience. Where previously 5.56mm gunfire was absolutely head-splitting, now it is fairly placid and tolerable. A clear benefit
You’ll still want ear pro thanks to the sonic crack created by the bullet in flight. However, particularly when running the gun indoors, the suppressor makes that experience much more palatable.
The end result allows you to communicate with both family and responding Law Enforcement should you ever be called upon to use the weapon for its intended purpose.

Deadly Combo: Dead Air CT5P + Sig MCX
It’s a buyer’s market for guns and gear these days. You can land a bargain basement AR, a cheap can, and a piece of knockoff Chicom glass for not a lot of cash.
However, that’s a bit like buying a cut-rate parachute. The synergistic melding of the SIG MCX, the Dead Air CT5P Patrol suppressor, and the EOTech EXPS Holosight is greater than the sum of its parts.
None of it is cheap, but this is the ideal Law Enforcement patrol rifle. It’s the next best thing to having your own live-in cop.
