The arrival of Lyman’s Sonicore suppressor line gives buyers another option in the growing market for affordable, modular suppressors. At first glance, Sonicore and Tuna Cans have several things in common: both offer modular designs, both emphasize value, and both cover many of the most common rifle, pistol, and rimfire calibers.
Under the surface, however, the two product lines take noticeably different approaches to materials, construction, mounting systems, weight, and intended firing schedules.
This comparison looks at Tuna Cans vs. Lyman Sonicore from a technical standpoint, including the differences between their .22, 5.56/.223, .30-caliber, and 9mm suppressors.
Tuna Cans vs. Sonicore Silencers: Quick Comparison
At first glance, Tuna Cans and Lyman Sonicore suppressors compete in a similar price range and share some of the same basic ideas, including modular construction and multiple caliber options. The biggest difference is what you’re actually getting for that money.
Tuna Cans puts substantially more emphasis on materials, durability, and manufacturing capability at its price point. Our lightweight suppressors use high-strength 7075 aluminum, while our heavy-duty centerfire models are constructed from heat-treated 17-4 precipitation-hardening stainless steel. Sonicore uses 6026-T9 aluminum and 303 stainless steel, depending on the model.
Those are not simply different grades of otherwise interchangeable materials. Published mechanical-property data shows 7075-T6 with substantially greater tensile and yield strength than 6026-T9, while properly heat-treated 17-4 PH stainless can achieve dramatically greater strength than 303 stainless. Finished suppressor performance depends on more than material specifications alone, but the difference helps explain why Tuna Cans can offer products rated for substantially more demanding firing schedules.
Tuna Cans suppressors are also manufactured in-house in the United States. Rather than choosing lower-cost materials to hit an affordable price point, our goal has been to manufacture suppressors from premium materials while keeping the final price accessible.
That creates what we believe is one of the strongest value propositions in the category: premium construction and heavy-duty capability without moving into premium suppressor pricing.

More Material for Your Money
This is where the Tuna Cans vs. Sonicore comparison becomes particularly important for value-conscious buyers.
Affordable suppressors often require compromises somewhere in the design. One way to reduce manufacturing cost and weight is through material selection. Tuna Cans takes a different approach: we use the same types of high-strength materials commonly associated with much more expensive suppressors while keeping our products within the affordable end of the market.
Our aluminum suppressors use 7075 rather than a lower-strength aluminum alloy, and our heavy-duty stainless models use heat-treated 17-4 PH rather than a general-purpose machinable stainless such as 303. We also manufacture our suppressors in-house in the United States, giving us direct control over machining, assembly, and production.
The result is that buyers don’t have to choose between an affordable suppressor and premium construction.
For shooters primarily concerned with minimizing weight, Sonicore’s aluminum-focused construction may have advantages. But for buyers comparing Tuna Cans vs. Lyman Sonicore based on what they receive for their money, Tuna Cans offers higher-strength material options, full-auto and belt-fed capability on applicable models, a broader range of constructions and calibers, and U.S. in-house manufacturing at a similar overall price point.
Tuna Cans vs. Sonicore: The Biggest Difference Is Construction
Perhaps the most significant difference between the two suppressor lines is the choice of materials.
Lyman states that Sonicore suppressors use 6026-T9 aluminum and 303 stainless steel, depending on the model. Its Rekkr and Paradox centerfire rifle suppressors use aluminum baffle modules combined with 303 stainless-steel inserts to form what Lyman describes as a stainless-steel “core.” The Skarv 22 is constructed from 6026-T9 aluminum, while the Valor 9 uses 6026-T9 aluminum and 303 stainless steel.
Tuna Cans uses several different construction strategies across its lineup.
Its dedicated 5.56, 30 Cal, 9mm, .40/10mm and .46-caliber stainless suppressors are machined from heat-treated 17-4 stainless steel. Other models, including the .22, FAT9 and SLIM9 families, use 7075 aluminum. The BlackFin takes a hybrid approach, combining a heat-treated 17-4 stainless blast chamber and first baffle with 7075 aluminum for the remaining baffles and end cap.
That means this isn’t simply an “aluminum suppressor versus stainless suppressor” comparison. Tuna Cans offers both lightweight aluminum designs and considerably heavier all-stainless designs depending on the intended application.
7075 Aluminum vs. 6026-T9 Aluminum
Both companies use aluminum where keeping weight down is important, but they use different alloys.
Sonicore specifies 6026-T9 aluminum, while Tuna Cans’ aluminum models use 7075 aluminum.
Published mechanical-property data provides some useful context:
| Material | Published Tensile Strength | Published Yield/Proof Strength |
| 6026-T9 aluminum | ~360 MPa | ~330 MPa |
| 7075-T6 aluminum | ~540 MPa | ~485 MPa |
On those published bar-property values, 7075-T6 has approximately 50% greater ultimate tensile strength and about 47% greater yield strength than 6026-T9. Actual finished-component performance depends on temper, geometry, machining and other manufacturing factors, so alloy numbers alone should not be interpreted as a direct prediction of suppressor lifespan.
The difference does, however, illustrate the design philosophy behind Tuna Cans’ aluminum models: use a higher-strength aluminum alloy while preserving the weight advantages associated with aluminum construction.
17-4 Stainless Steel vs. 303 Stainless Steel
The difference becomes even greater when looking at the stainless alloys used by the two companies.
Lyman specifies 303 stainless steel for the stainless components in its Rekkr and Paradox suppressors and identifies 303 stainless alongside 6026-T9 in the Valor 9.
Tuna Cans’ stainless models use heat-treated 17-4 precipitation-hardening stainless steel.
303 is an austenitic stainless alloy particularly well known for machinability. Published ATI data for 303 lists tensile strength in the approximately 517–621 MPa range.
17-4 PH, by comparison, is specifically capable of being precipitation hardened. Its mechanical properties vary substantially with heat-treatment condition. As a reference point, published H900 data lists tensile strength around 1,310 MPa and yield strength around 1,170 MPa.
For that reason, simply calling both materials “stainless steel” misses a considerable metallurgical difference between them.
Full-Auto and Belt-Fed Rating: A Major Difference in Intended Use
Another important difference between Tuna Cans and Lyman Sonicore is the firing schedule each product line is designed and rated to handle.
Tuna Cans offers suppressors rated for full-automatic and belt-fed use, depending on the model and applicable caliber/barrel-length requirements. This capability is closely tied to the heavier-duty construction used throughout the Tuna Cans lineup, particularly the models built from heat-treated 17-4 stainless steel.
Lyman takes a different approach with Sonicore. Lyman specifically states that Sonicore suppressors are not full-auto rated due to the materials used in their construction. Lyman also publishes rate-of-fire recommendations for certain Sonicore models and warns that exceeding those recommended firing schedules can result in premature suppressor failure.
This represents more than a difference in material specifications on paper. It reflects two different design priorities. Sonicore places greater emphasis on keeping suppressor weight down through its use of aluminum and 303 stainless-steel components, while Tuna Cans offers heavier-duty constructions intended to tolerate substantially more demanding firing schedules.
For buyers comparing Tuna Cans vs. Sonicore, particularly for 5.56 and other centerfire applications, the manufacturer’s firing rating is therefore an important specification to consider alongside weight, dimensions, mounting system and material choice.
Tuna Cans 5.56 vs. Lyman Sonicore .223
For someone comparing a Tuna Cans 5.56 vs. Sonicore 5.56/.223 suppressor, the difference in construction philosophy is particularly obvious.
Sonicore offers .223 versions of both the Rekkr and Paradox, with direct-thread and over-barrel configurations. Both use 6026-T9 aluminum baffle modules with 303 stainless-steel inserts. The Rekkr uses thicker walls and is positioned by Lyman for higher-volume semi-automatic use, while the Paradox prioritizes reduced weight.
The direct-thread Rekkr is 7.60 inches long, 1.77 inches in diameter and 14.6 ounces at full length. The Paradox DT maintains the same 7.60-inch length and 1.77-inch diameter but drops weight to 13 ounces. Lyman lists neither model as full-auto rated.
The Tuna Cans 5.56 family takes a different approach. The S, L and XL models use heat-treated 17-4 stainless steel rather than an aluminum/stainless hybrid construction. The 5.56 S, for example, is 6.25 inches long, 1.50 inches in diameter and weighs 16 ounces. The 5.56 L increases to 7.76 inches and 20 ounces. Both are listed by Tuna Cans as full-auto rated for .223/5.56 subject to the published barrel-length restrictions.
In practical design terms, Sonicore emphasizes lower weight, while the Tuna Cans 5.56 series accepts additional weight in exchange for an all-17-4 stainless construction and a different manufacturer-rated firing envelope.
There is also an important mounting difference. Sonicore’s Rekkr and Paradox are direct-thread systems, with over-barrel versions also available. Tuna Cans’ current stainless 5.56 models use the common 1.375×24 HUB interface, allowing the suppressor body to accept different compatible mounting systems rather than permanently committing the user to one direct-thread configuration.
Tuna Cans .30 Cal vs. Sonicore .30 Cal
The Tuna Cans .30 Cal vs. Sonicore .30 Cal comparison follows a similar pattern.
Lyman offers .30-caliber versions of its Rekkr and Paradox in both direct-thread and over-barrel configurations. Like the .223 versions, these use 6026-T9 aluminum modules and 303 stainless-steel baffle inserts.
Tuna Cans offers two distinct approaches in this category.
The regular 30 Cal S, L and XL suppressors use heat-treated 17-4 stainless steel throughout. The 30 Cal S, for example, is 6.24 inches long, weighs 16 ounces and uses a HUB-compatible mounting interface.
The BlackFin S, L and XL provide an alternative for shooters prioritizing reduced weight. The BlackFin combines a heat-treated 17-4 blast chamber and first blast baffle with 7075 aluminum for the remaining baffles and end cap. The BlackFin L weighs 12.5 ounces despite measuring 8.5 inches long.
This gives Tuna Cans two materially different answers to the .30-caliber problem: an all-stainless platform focused on strength and a hybrid 17-4/7075 platform focused more heavily on weight reduction.
Tuna Cans 9mm vs. Lyman Sonicore Valor 9
The 9mm category has an even wider range of construction choices.
Lyman’s Sonicore Valor 9 is a modular 9mm pistol suppressor measuring 7.32 inches long, 1.36 inches in diameter and 7.8 ounces at full length. It uses eight removable baffles, incorporates 6026-T9 aluminum and 303 stainless steel, and includes a booster and piston. Lyman does not list it as full-auto rated.
Tuna Cans currently offers three different 9mm platforms:
- SLIM9 S and XL — compact 7075-aluminum designs.
- FAT9 S, L and XL — larger-volume 7075-aluminum designs.
- 9mm S, L and XL — heat-treated 17-4 stainless-steel designs.
The result is a substantially different product strategy. Rather than one construction optimized around a particular balance of weight and durability, Tuna Cans separates those priorities into multiple 9mm families.
For example, the SLIM9 S weighs only 2.5 ounces and measures 3 inches long, using 7075 aluminum throughout. At the other end of the spectrum, the stainless Tuna Cans 9mm S weighs 16 ounces and uses heat-treated 17-4 stainless steel.
The FAT9 sits between those approaches, using 7075 aluminum with a larger 1.625-inch diameter and HUB mounting interface.
So a comparison of Tuna Cans 9mm vs. Sonicore Valor 9 depends heavily on which Tuna Cans family is being considered.
Tuna Cans .22 vs. Sonicore Skarv 22
The rimfire comparison is much more direct because both products use all-aluminum modular construction.
The Sonicore Skarv 22 uses 6026-T9 aluminum, measures 5 inches long and 1.13 inches in diameter, and weighs 3.2 ounces. It uses a 1/2×28 direct-thread mount and is not listed by Lyman as full-auto rated.
The Tuna Cans .22 S uses 7075 aluminum, measures 3 inches long and approximately 1.125 inches in diameter, and weighs 2.5 ounces. Tuna Cans lists it as full-auto rated for .22 LR under its published usage guidance.
Tuna Cans also offers .22 XL and .22 XXL versions with 10- and 15-baffle configurations respectively, whereas the Sonicore lineup currently centers around the Skarv 22 platform.
For buyers specifically researching Tuna Cans .22 vs. Sonicore Skarv 22, the alloy selection and available size configurations are therefore two of the clearest differences.
Calibers Where Sonicore Currently Has No Direct Equivalent
The current Tuna Cans modular lineup contains 26 models/configurations spread across .22, 5.56/6mm, .30 caliber, 9mm, .40/10mm and .46-caliber categories.
Lyman introduced Sonicore as four principal families: Skarv 22, Rekkr, Paradox and Valor 9, with Rekkr and Paradox available in .223 and .30-caliber configurations.
As a result, Tuna Cans currently has dedicated .40/10mm and .46-caliber suppressor families for which the announced Sonicore lineup does not have a direct same-caliber counterpart.
Both Designs Are Modular, but They Approach Modularity Differently
One thing Tuna Cans and Sonicore genuinely have in common is modular construction.
Lyman designed Sonicore models so modules can be removed to reduce overall suppressor length, and the company emphasizes user servicing and disassembly as core features of the line.
Tuna Cans likewise uses serviceable threaded baffle stacks across much of its lineup, with different S, L and XL configurations allowing buyers to choose different baffle counts and overall sizes from the outset.
The difference is therefore less about whether the suppressors are modular and more about the materials, mounting systems and firing envelopes surrounding that modular architecture.
So, How Do Tuna Cans and Sonicore Actually Differ?
The biggest difference between Tuna Cans and Lyman Sonicore is not simply weight, modularity, or mounting style. It is what each company is delivering at a similar price point.
Sonicore’s approach emphasizes lightweight construction, modularity, and direct-thread simplicity. Its centerfire rifle suppressors use 6026-T9 aluminum modules with 303 stainless-steel inserts, helping keep weight relatively low. Lyman also offers different Sonicore configurations aimed at hunting and higher-volume semi-automatic use, but states that the Sonicore line is not full-auto rated.
Tuna Cans takes a different approach to value. Rather than relying on one construction strategy, we use materials based on the intended application. Our lightweight models use high-strength 7075 aluminum, hybrid models combine 7075 with heat-treated 17-4 stainless steel, and our heavy-duty centerfire suppressors use heat-treated 17-4 stainless throughout. Many of our centerfire models also use the standardized 1.375×24 HUB mounting interface and are rated for full-auto—and, where applicable, belt-fed—use.
Just as importantly, Tuna Cans suppressors are manufactured in-house in the United States. By controlling production ourselves, we are able to put higher-cost materials and heavier-duty construction into suppressors while keeping them in the same general affordable price category as competing modular designs.
That is ultimately where we believe the value difference becomes clear.
A buyer comparing Tuna Cans vs. Lyman Sonicore is not simply choosing between two similarly priced modular suppressors. In many cases, the Tuna Cans option provides higher-strength materials, more demanding firing ratings, HUB compatibility, U.S. in-house manufacturing, and a broader range of construction choices without requiring the buyer to move into a substantially higher price tier.
There are still tradeoffs. An all-17-4 stainless suppressor will generally weigh more than an aluminum-focused design, and shooters whose highest priority is minimizing weight may prefer that compromise. But for buyers prioritizing durability, material quality, firing capability, mounting flexibility, and overall value for the money, Tuna Cans is designed to deliver considerably more hardware at a comparable price point.
