Description
Big-bore suppressors tend to be heavy, bulky, and stuck on one gun. The AnechoX 45 goes the other direction. At 6.6 inches long and 8.2 ounces (about 9.1 with the included direct thread adapter), this compact titanium can covers an enormous range of firearms, from .45 ACP and 10mm pistols through 44 Mag and 454 Casull revolvers, up to serious rifle rounds like 450 Bushmaster, 45-70 +P, and even .458 Win Mag. For a hunter who wants to quiet down a big-bore rifle without turning it into a boat anchor, this is one of the lightest options in its class.
Inside the AnechoX 45
The body is Grade 5 titanium, with 17-4 H900 stainless steel used for the blast chamber and blast baffles where heat and pressure hit hardest. That combination keeps weight down while standing up to the erosion that magnum rifle cartridges dish out. ANECHOIC builds every AnechoX around its X-Baffle Anechoic Chamber System with an interrupted central tube, a design aimed squarely at knocking down both sound and recoil from high-energy cartridges. The whole thing wears Cerakote C Series, a high-temperature ceramic finish that shrugs off weather and hard field use. It is full-auto rated to 100 rounds of .45 ACP and carries defined rapid-fire ratings for rifle cartridges, and the user-serviceable design means you can open it up and clean it yourself.
Mounting Options That Work With Your Gear
The AnechoX 45 ships with a 5/8×24 direct thread adapter installed, so most big-bore rifles are ready to go out of the box. The rear of the can uses the industry standard 1-3/8×24 thread, which opens the door to HUB mounts, pistons, boosters, tri-lugs, and quick-detach systems from across the market. Running it on a tilting-barrel pistol? Add a piston and you are set. ANECHOIC also includes a caliber-specific Quiet Cap alongside the standard Flow-Cap, letting you tune the front end for maximum sound reduction on your particular caliber.
One can, a whole safe full of guns it can serve, and a lifetime warranty behind it. That is a strong case for making the AnechoX 45 your do-it-all big-bore suppressor.

Frequently Asked Questions
Can I run the AnechoX 45 on a .45 ACP pistol with a tilting barrel?
Yes, but you will need a booster or piston, which is standard for any suppressor on a Browning-style tilting barrel. The rear of the AnechoX 45 uses the industry standard 1-3/8×24 thread, so it accepts common pistons, boosters, and Nielsen devices already on the market. On fixed-barrel guns and rifles, the included 5/8×24 direct thread adapter has you covered.
Is the AnechoX 45 really rated for .458 Win Mag?
It is. ANECHOIC designed this can for high-energy rifle cartridges in the 4,000 to 6,000 ft-lb range, with a rapid-fire rating of 8 rounds of .458 Mag and 20 rounds of 45-70 +P or 450 Bushmaster. The 17-4 stainless blast chamber and baffles are there specifically to handle that kind of pressure and heat. Maximum bullet diameter is .458 inches.
How do I clean the AnechoX 45?
The AnechoX 45 is fully user serviceable, so you can disassemble it for cleaning rather than sending it back to the factory or relying on solvent soaks alone. That matters most if you plan to shoot a lot of dirty pistol ammo like .45 ACP, which builds carbon and lead fouling faster than rifle rounds. Regular teardowns keep weight and sound performance where they should be.
What is the difference between the AnechoX 45 and the AnechoX 45L?
The 45 is the compact version at 6.6 inches and 8.2 ounces, built for maneuverability and minimal added weight on a hunting rifle or handgun. The 45L is the full-length model at 8.2 inches, which trades some compactness for stronger sound and recoil reduction. If you want the shortest, lightest big-bore can, the 45 is the pick; if maximum quiet is the goal, look at the 45L.
