2025 Silencer Summit: The HARMONIX® platform ranked #1 out of 22 suppressors at the Shooter’s Ear in 9mm (133.20 dB), #1 in peak pressure (91.45 Pa), and #2 in dB(A). In 5.56, it placed top 8 in a field of 86. Because all HARMONIX® models share the same baffle geometry, these results apply equally to the Ti•CONEL®. All testing independently conducted by Thunder Beast Arms Corporation.
Choosing your tier: All HARMONIX® suppressors suppress the same—the difference is material. If absolute minimum weight is the priority, the ION (7.84 oz, $975) is all titanium—just 0.56 oz lighter. If you need superalloy from end to end for belt-fed or sustained full-auto duty, the Sentry (15.7 oz, $1,099) runs Haynes 282 throughout. Compare all three tiers →
Two Materials, One Suppressor: The Ti•CONEL® Approach
Not every position in a suppressor stack sees the same conditions. The blast baffle—the first baffle that takes the full brunt of every round’s muzzle blast—experiences the highest temperatures and the most violent gas dynamics in the entire suppressor. The rearward baffles and body see progressively less heat as gas expands and cools through the stack. The Ti•CONEL® was designed around this reality: put a superalloy where the heat is worst, and use titanium everywhere the thermal demands allow it.
The result is a suppressor that weighs just 8.4 oz—0.56 oz more than the all-titanium ION—while gaining a machined Inconel 718 blast baffle at the most critical position. The 3D-printed Grade 5 Titanium body provides the structural envelope, corrosion resistance, and lightweight platform, while the Inconel 718 blast baffle handles sustained temperatures up to ~1,300°F (704°C) where titanium would begin to lose strength.
Why This Combination Works
◆
Inconel 718 Blast Baffle
Inconel 718 is a precipitation-hardened nickel-chromium superalloy used in jet engine turbine discs, rocket motor components, and nuclear reactor cores—applications where the material must maintain structural integrity under extreme heat and cyclic stress. In the Ti•CONEL®, this machined superalloy blast baffle handles the thermal spike of every round at the hottest position in the stack, providing durability that approaches the all-superalloy Sentry at that critical location.
▸
Grade 5 Titanium Body
The rest of the suppressor—the 3D-printed body and rearward baffles—is Grade 5 Titanium (Ti-6Al-4V), the same aerospace-standard alloy used throughout the ION. At roughly half the density of nickel superalloys, titanium is what keeps the Ti•CONEL® at 8.4 oz instead of the Sentry’s 15.7 oz. Rearward of the blast baffle, gas temperatures are lower and titanium’s mechanical properties are well within their operating envelope.
↻
The Weight Math
The blast baffle is a small fraction of the suppressor’s total volume, which is why swapping it from titanium to Inconel 718 adds only 0.56 oz (from 7.84 oz to 8.4 oz). That’s the weight of roughly three .223 cartridges for a meaningful upgrade in blast baffle durability. The remaining body stays titanium, keeping the Ti•CONEL® closer to ION weight than Sentry weight.
⌖
Machined vs. Printed
Unlike the ION and Sentry (which are fully 3D-printed), the Ti•CONEL® blast baffle is CNC machined from wrought Inconel 718 bar stock. Wrought Inconel 718 has a longer track record in high-stress aerospace applications and offers tightly controlled material properties. The machined blast baffle is integrated into the 3D-printed titanium body during assembly.

For most shooters, the Ti•CONEL® is the Goldilocks option. It gives up just 0.56 oz compared to the ION—a difference you will not feel on the muzzle—while gaining a blast baffle that can handle more than double the operating temperature of titanium. Compared to the Sentry, it delivers the same blast baffle class of durability at roughly half the total weight. The only scenario where the Sentry pulls ahead is when the entire suppressor body sees sustained extreme heat: belt-fed platforms, extended full-auto on select-fire hosts, or magnum cartridges at institutional round counts.
The name, decoded: Ti•CONEL® = Ti (titanium) + CONEL (Inconel). The name tells you exactly what’s inside: a titanium suppressor with an Inconel blast baffle. Simple as that.
Inconel 718: The Superalloy at the Heart of the Ti•CONEL®
Inconel 718 is a precipitation-hardened nickel-chromium superalloy that accounts for a significant share of all superalloy production worldwide. It was originally developed for gas turbine applications and has become the workhorse superalloy of the aerospace and energy industries—used in jet engine turbine discs, compressor blades, rocket motor thrust chambers, and nuclear reactor components. Its combination of high-temperature strength, excellent fatigue life, and well-characterized manufacturing properties makes it one of the most proven and trusted superalloys in existence.
What makes Inconel 718 ideal for a suppressor blast baffle is its creep and rupture strength at elevated temperatures. The blast baffle experiences a rapid thermal spike with every round, followed by sustained heat as propellant gases flow through the stack. Inconel 718 maintains excellent mechanical properties up to approximately 1,300°F (704°C)—more than double the operating ceiling of Grade 5 Titanium. This means the Ti•CONEL®’s blast baffle resists the deformation, thinning, and erosion that can affect titanium blast baffles under sustained high-volume fire.
The Ti•CONEL® blast baffle is CNC machined from wrought Inconel 718 bar stock rather than 3D-printed. Wrought material offers tightly controlled grain structure and mechanical properties with decades of aerospace qualification data behind it. This machined blast baffle is then integrated into the 3D-printed titanium body, combining the best manufacturing method for each material at each position in the stack.
Independent Testing: 2025 Thunderbeast Silencer Summit
The Thunderbeast Silencer Summit is one of the most rigorous independent suppressor testing events in the industry, conducted by Thunder Beast Arms Corporation under standardized conditions with calibrated equipment. The summit tested the HARMONIX® Sentry configuration, but because all HARMONIX® models share identical baffle geometry, these sound suppression results apply to the Ti•CONEL® as well.

The Ti•CONEL® delivers this #1-ranked sound performance at just 8.4 oz—with a superalloy blast baffle that can sustain the thermal demands of high-volume shooting. In 5.56, the HARMONIX® placed in the top 8 out of 86 while being one of the shortest suppressors in the top 10 at just 6.75″.
Same baffle design, same sound: The summit tested the Sentry (Haynes 282) configuration, but because all HARMONIX® models share the same baffle geometry, sound suppression is comparable across ION, Ti•CONEL®, and Sentry. The
ION delivers this performance at 7.84 oz; the
Sentry adds full-body superalloy durability at 15.7 oz.
Which Ti•CONEL® Caliber Is Right for You?
All three Ti•CONEL® suppressors share the same external dimensions, weight, hybrid Ti + Inconel 718 construction, and full-auto rating—the only difference is bore diameter. A tighter bore delivers better suppression for that specific caliber, while a wider bore adds multi-caliber versatility.

Frequently Asked Questions
Why is the Ti•CONEL® considered the sweet spot of the lineup?
The blast baffle is the hottest position in any suppressor—it takes the full force of every round’s muzzle blast. The Ti•CONEL® puts a machined Inconel 718 superalloy baffle at that critical position while keeping the rest of the suppressor in lightweight Grade 5 Titanium. The result is 8.4 oz—just 0.56 oz more than the all-titanium ION—with a blast baffle rated to ~1,300°F instead of titanium’s ~600°F. You get superalloy durability where it matters most without the weight penalty of the all-superalloy Sentry (15.7 oz).
What does the Ti•CONEL® name mean?
Ti = titanium, CONEL = Inconel. The name tells you exactly what’s inside: a titanium suppressor body with an Inconel blast baffle.
When should I choose the Ti•CONEL® over the ION?
If you shoot at higher volume than the average range session—frequent extended mag dumps, regular full-auto fire, short-barreled rifles at high round counts—the Inconel 718 blast baffle gives you meaningfully more thermal headroom than the ION’s all-titanium construction, at a barely perceptible weight difference (0.56 oz) and $75 more. If your shooting pattern is typical range use, hunting, competition, or home defense, the
ION saves you $75 with no practical difference in performance.
When should I choose the Ti•CONEL® over the Sentry?
Almost always, unless you need superalloy throughout the entire suppressor body. The Ti•CONEL® and
Sentry both have superalloy blast baffles, but the Ti•CONEL® weighs 8.4 oz versus the Sentry’s 15.7 oz. The Sentry only pulls ahead when the rearward baffles and body also see sustained extreme heat: belt-fed platforms, extended full-auto on select-fire hosts, or magnum cartridges at institutional round counts measured in tens of thousands of rounds per year.
Why is the blast baffle machined instead of 3D-printed?
The Ti•CONEL® blast baffle is CNC machined from wrought Inconel 718 bar stock. Wrought material has a longer track record in high-stress aerospace applications and offers tightly controlled grain structure and mechanical properties. For the blast baffle—the single most thermally stressed component—Faxon chose the manufacturing method with the deepest body of qualification data.
What is the difference between ION, Ti•CONEL®, and Sentry?
All three share the same external dimensions, internal baffle design, and sound performance. The difference is material:
ION is all Grade 5 Titanium (7.84 oz, $975), Ti•CONEL® is Grade 5 Titanium with a machined Inconel 718 blast baffle (8.4 oz, $1,050), and
Sentry is all Haynes 282 superalloy (15.7 oz, $1,099). ION is lightest, Sentry is most durable, and Ti•CONEL® splits the difference.
Is the HARMONIX® full-auto rated?
Yes. All nine HARMONIX® configurations (three material tiers × three calibers) are full-auto rated with no minimum barrel length restriction for semi-auto or bolt action hosts.
What mount system does the HARMONIX® use?
All HARMONIX® suppressors use the Faxon HUB mount interface. Each Ti•CONEL® ships with a Direct Thread HUB Adapter (1/2x28 for 5.56, 5/8x24 for .30 and .36 Cal). For quick-detach capability, pair with a
MuzzLok® Plan B Compatible muzzle device. Standard MuzzLok® devices are not designed for suppressor mounting.
How did the HARMONIX® perform at the Thunderbeast Silencer Summit?
At the 2025 Thunderbeast Silencer Summit, the HARMONIX® ranked #1 out of 22 suppressors at the Shooter’s Ear in 9mm in both dB and peak pressure, and #2 in dB(A). In 5.56, it placed #5 out of 86 at Muzzle Right and top 8 across all highlighted metrics. The summit tested the Sentry configuration, but because all three material tiers share the same baffle geometry, sound suppression results apply to the Ti•CONEL® as well. All testing independently conducted by TBAC.
Is the $200 tax stamp still required?
The $200 tax stamp fee has been eliminated. Suppressors are still regulated under the National Firearms Act (NFA), and you still need to submit an ATF eForm 4 through a licensed dealer. Your dealer handles the paperwork at the time of purchase, and current eForm 4 processing times are significantly faster than they were a few years ago.
Can I use one Ti•CONEL® on multiple hosts?
Yes. With the
MuzzLok® Plan B Compatible quick-detach system, you can move a single Ti•CONEL® between multiple hosts in seconds. Make sure the suppressor’s bore is large enough for the caliber—a .30 Cal can also suppress 5.56, but a 5.56 cannot safely be used on .30 cal cartridges.
