HARMONIX® Ti-CONEL® Guide: Why Titanium + Inconel and How to Pick Your Caliber

The suppressor market has never been short on trade-offs. Go lightweight with titanium and you get a can that’s easy to carry all day—but the blast baffle takes a beating on high-volume days and erodes faster than you’d like. Go durable with a superalloy and the throat will outlast the barrel—but you’re adding nearly a pound to the end of your rifle. For years, shooters have had to pick a side.

The Harmonix® Ti•CONEL® was designed to end that compromise. It pairs a 3D-printed Grade 5 Titanium body with a precision-machined Inconel 718 blast baffle—putting the right material in the right place. The result is a suppressor that weighs 8.4 oz without a mount, handles full-auto fire, and gives you throat durability that a pure titanium design can’t match.

If you’re considering a Ti•CONEL® or trying to decide between it and the other Harmonix® models, this guide covers everything you need to know: the materials, the manufacturing, how to pick a caliber, and where the Ti•CONEL® fits in the lineup.

Two Materials, One Suppressor

Every Harmonix® suppressor shares the same external geometry and internal baffle design. That means sound performance is consistent across the entire lineup—what changes between models is the material and how it’s made.

The Ti•CONEL® uses two distinct materials and two manufacturing methods:

The body and baffle stack are additively manufactured (3D-printed) from Grade 5 Titanium (Ti-6Al-4V)—the same aerospace-grade alloy used in aircraft structural components and medical implants. Titanium is about 40% lighter than stainless steel with excellent corrosion resistance, and additive manufacturing allows Faxon to build internal baffle geometries that would be impossible with traditional machining.

The primary blast baffle—the first baffle the propellant gases hit after leaving the muzzle—is precision-machined from Inconel 718. This is a nickel-chromium superalloy originally developed for jet engine turbine blades, where it operates at temperatures above 1,300°F under extreme cyclic stress. In a suppressor, the blast baffle position sees the highest temperatures, the most erosive gas flow, and the greatest mechanical stress. Titanium works well everywhere else in the stack, but at the throat, Inconel 718 provides a level of durability that titanium can’t match under sustained fire.

The exterior is finished with a high-temperature ceramic coating that adds thermal protection and abrasion resistance without adding measurable weight.

The name “Ti•CONEL” comes from this combination: Titanium body + Inconel blast baffle.

Where the Ti•CONEL® Fits in the Harmonix® Lineup

Faxon offers three material tiers in the Harmonix® family. All three share the same dimensions (6.75″ long, 1.675″ max OD, 1.5″ wrench flats), the same baffle design, and the same HUB mount interface. The difference is what they’re made of:

• Harmonix® ION — Fully 3D-printed Grade 5 Titanium. 7.84 oz. The lightest suppressor in the lineup, built for shooters who prioritize weight above everything else. Ideal for bolt guns, precision builds, and moderate round counts where absolute minimum weight matters most.
• Harmonix® Ti•CONEL® — 3D-printed Grade 5 Titanium body + machined Inconel 718 blast baffle. 8.4 oz. Only 0.56 oz heavier than the ION, but with a blast baffle that won’t erode under sustained fire, full-auto use, or magnum-class cartridges. This is the most versatile choice in the lineup.
• Harmonix® Sentry — Fully 3D-printed Haynes 282 superalloy. 15.7 oz. Maximum durability from end to end. Built for the hardest use cases where weight is secondary to absolute longevity—think belt-fed, high-round-count duty, or platforms where the suppressor will see more abuse than most shooters put on a barrel in a lifetime.

The Ti•CONEL® sits in the middle and hits what most shooters consider the sweet spot: near-ION weight with blast baffle durability that handles everything from high-volume training days to .300 Win Mag. If you’re buying one Harmonix® suppressor, the Ti•CONEL® is the one that covers the widest range of use cases without compromise.

Choosing a Caliber: 5.56 vs. .30 Cal vs. .36 Cal

The Ti•CONEL® is available in three bore sizes. All three share the same external dimensions, weight, and $1,050 MSRP—the only difference is bore diameter and the Direct Thread HUB Adapter that ships in the box.

Ti•CONEL® 5.56 — Dedicated AR-15 Suppression

Bore: .224″ • Ships with 1/2x28 Direct Thread HUB Adapter

The dedicated 5.56 bore is sized specifically for .224-caliber projectiles. A tighter bore means less gas blowby through the baffle stack, which translates to better sound suppression and less gas blowback to the shooter—especially noticeable on short-barreled AR-15s. If the AR-15 is your primary suppressor host and you don’t need to move the can between calibers, this is the model that gives you the best 5.56 performance from a suppressor this light.

Compatible calibers: 5.56 NATO, .223 Remington, .224 Valkyrie, .22 Nosler, and any cartridge with a .224″ or smaller projectile.

Ti•CONEL® .30 Cal — The Multi-Caliber Workhorse

Bore: .308″ • Ships with 5/8x24 Direct Thread HUB Adapter

The .30 cal bore covers the most popular rifle cartridges in the world: .300 Win Mag, .308 Winchester, 6.5 Creedmoor, .300 Blackout, 5.56/.223, 6mm ARC, and 6.5 Grendel. If you own rifles in multiple .30 cal or smaller cartridges and want one suppressor that moves between them, this is the most practical choice. The Inconel 718 blast baffle is especially important here—magnum-class cartridges like .300 Win Mag generate higher chamber pressures and muzzle energy that put more stress on the primary baffle.

Ti•CONEL® .36 Cal — The Widest Versatility

Bore: .360″ • Ships with 5/8x24 Direct Thread HUB Adapter

The .36 cal bore is the largest in the Harmonix® lineup and covers everything the .30 cal does plus 8.6 Blackout, 9mm PCC, .350 Legend, and .338 Federal. If you’re building a suppressed 8.6 BLK bolt gun, running a 9mm AR-9 or Scorpion, or want maximum caliber flexibility across your collection, the .36 Cal is the only Ti•CONEL® that covers all of those platforms.

Quick Decision Guide

• You only shoot 5.56/.223 → Get the 5.56. Tighter bore = better suppression for your platform.
• You shoot .308, 6.5 CM, .300 BLK, or .300 Win Mag → Get the .30 Cal. Covers the widest range of popular rifle cartridges.
• You need 8.6 BLK, 9mm, .350 Legend, or .338 → Get the .36 Cal. It’s the only bore size that covers those calibers.
• You want one can for everything → Get the .36 Cal. Wider bore means slightly less suppression on 5.56 than the dedicated can, but it handles every caliber from .223 to 8.6 BLK.

Mounting: HUB Mount & MuzzLok® Plan B Compatible

All Ti•CONEL® suppressors use the Faxon HUB mount interface. Each ships with a Direct Thread HUB Adapter—1/2x28 for the 5.56, 5/8x24 for the .30 and .36 Cal. Thread it on, torque to spec, and verify concentricity before your first shot.

For quick-detach capability, pair any Ti•CONEL® with a MuzzLok® Plan B Compatible muzzle device. The MuzzLok® Plan B Compatible system lets you attach and detach the suppressor in seconds without tools—useful if you’re moving a single can between multiple hosts.

Note: Standard MuzzLok® muzzle devices are not designed for suppressor mounting. For suppressor use, make sure you’re using MuzzLok® Plan B Compatible devices specifically.

Tax Stamp & Purchase Process

Suppressors are regulated under the National Firearms Act (NFA). You’ll need to submit an ATF eForm 4 through a licensed dealer to take possession. The $200 tax stamp fee has been eliminated, but the eForm 4 approval process is still required. Your dealer can walk you through the paperwork at the time of purchase—it’s straightforward, and current eForm 4 processing times are significantly faster than they were a few years ago.

Care & Cleaning

All Harmonix® suppressors—ION, Ti•CONEL®, and Sentry—are 3D-printed/additively manufactured and share the same care guidelines. Centerfire rifle suppressors accumulate less fouling than rimfire or pistol cans, but periodic cleaning extends the life of any suppressor. Ultrasonic cleaning with a titanium-safe solution is the recommended method—avoid highly alkaline cleaners that can damage the ceramic coating. For specific product recommendations, contact Faxon Customer Service.

The Bottom Line

The Harmonix® Ti•CONEL® exists because most shooters don’t want to choose between weight and durability. At 8.4 oz with a machined Inconel 718 blast baffle, it’s nearly as light as the all-titanium ION but built to handle full-auto fire, magnum cartridges, and high-round-count use that would stress a pure titanium throat over time.

Pick the 5.56 for dedicated AR-15 suppression. Pick the .30 Cal for multi-caliber rifle versatility. Pick the .36 Cal for the widest bore covering everything from 5.56 to 8.6 Blackout. All three are full-auto rated, HUB mount compatible, and made in the USA.
