New LANTAC Suppressor Accessories

Wednesday, June 11th, 2025

Lantac has been an industry leader in muzzle devices for some time. The introduction of the Dragon® Muzzle Brake offeredimproved recoil management and muzzle rise over traditional muzzle brakes.

The Dragon’s patented gas handling system reduces muzzle rise and recoil to nearly zero – making follow up shots smooth and fast.

The demand for suppressor mount variants utilizing theDragon’s unique design features have only increased.

Lantac has now introduced new variants of its Dragon Brake for the Plan-B mounting standard.

Lantac Plan-B mounts include the new Lamprey™ Flash Fider and Flash-Comp, as well as the very popular Dragon® Muzzle Brakes.

All Lamprey muzzle devices feature a patented design – offering improved signature reduction over many competitors. Its unique ‘toothed’ four tine design disrupts gas more efficiently and reduces flash intensity and duration.

Short and long versions of each device will provide users with a wide range of options and features.

If you have a HUB-compatible suppressor, Lantac’s new Plan-B& Direct Thread hub adapters are now also available.

The new Patent Pending Adaptable Core Hub can be fitted using a standard Armorers Barrel Nut Wrench. HUB variants include Plan-B to 1.375×24, 1/2-28 DT to 1.375×24 and 5/8-24 DT to 1.375×24.

Manufactured from both 17-4 H900 Stainless Steel and Grade 6 Titanium.

Lantac has long provided shooters who prefer Dead Air® Keymo™ mounts with the advanced weapon control features seen in the Dragon muzzle devices.

With the new Lantac Xeno Dragon, shooters can now enjoy advanced weapon control with the ability to mount the Dead Air XENO HUB.

Both mount designs are fully licensed from Dead Air socustomers suppressor warranty remains unaffected.

Both Keymo™ and Xeno™ mounts ship with timing shim set sets for easy install.

SilencerCo users who prefer the ASR mounting interface can also enjoy the benefits of the Dragon Muzzle Brake in various thread pitches and calibers.

Lantac continues to innovate and expand their muzzle device product line.

NSNs Assigned to FN’s Lightweight Intermediate Caliber Cartridge Carbine and Suppressor

Wednesday, June 11th, 2025

Over the weekend, Japanese X account @teppoblog surprised us with a post listing National Stock Numbers associated with the Lightweight Intermediate Caliber Cartridge (LICC) Individual Weapon System (IWS), a novel weapon and ammunition manufactured by FN America. We reached out to several sources to validate the NSNs and they came back as real. We must point out that Teppoblog has a history of sharing correct info.

The LICC IWS project originated in 2019 from requirements provided to the Irregular Warfare Technology Support Directorate (IWTSD), a government office, which is responsible for conducting research and development in support of U.S. and allied organizations involved in Irregular Warfare. In fact, one of those sponsors of this system, Canada Special Operations Forces Command just nominated the program’s caliber, 6.5 x 43mm (.264) for NATO Standardization. FN America was awarded a development contract and we’ve kept up on the program with a couple of updates. Last November, FN delivered carbines, machines guns, suppressors, and ammunition to several SOF organizations.

The LICC IWS has four purpose-built components:

• Lightweight ammunition family
• Improved Performance Carbine
• 25-round purpose-built, polymer magazine
• Signature Suppressor

These new NSNs pertain to the three variants of the Improved Performance Carbine (11.5” Close Quarters Battle (CQB), 14.5” Carbine, and 18.5” Recce (Designated Marksmanship Rifle)) as well as two suppressors associated with the system.

The NSNs are:

NSN 1005-01-729-0039, FN IMPROVED PERFORMANCE CARBINE 12.5 IN CQB WITH BII*

NSN 1005-01-729-0052, FN IMPROVED PERFORMANCE CARBINE 14.5 IN CQB WITH BII

NSN 1005-01-729-0046, FN IMPROVED PERFORMANCE CARBINE 18.12 IN REECE (sic) WITH BII

NSN 1005-01-728-9868, SUPPRESSOR, FLOW 264 FOR IMPROVED PERFORMANCE CARBINE

NSN 1005-01-728-9874, SUPPRESSOR, FLOW 7.62 FOR IMPROVED PERFORMANCE CARBINE

*Basic Issue Items

The suppressors are manufactured by HUXWRX.

The NSNs are managed by the Special Operations Forces Support Activity at Lexington Bluegrass Army Depot and are available for requisition by Army, Navy, Marine, Air Force and SOCOM elements and activities.

Coincidentally, they’ve added a belt-fed machine gun to the capability in the form of the FN Evolys, but we still haven’t seen an NSN. Logic goes, that if the carbines have them, it should as well.

FN has also demonstrated versions of Evolys in 7.62 NATO and 6.5 CM in addition to the .264 model developed for this program. In fact, the first version of Evolys seen in the US was as the 6.8mm candidate for Next Generation Squad Automatic Rifle which rolled into NGSW. While it proved a desirable candidate for NGSW, it was too heavy for the specs spelled out in the requirement.

Due to the multiple caliber options, a forward leaning organization could buy the LICC machine gun and then arrange for the conversion kit from FN America for the desired caliber.

Likewise, we have not yet seen any Department of Defense Identification Codes (DODIC) for the ammunition. Not saying they don’t exist, but a reliable source of .264 ammunition is critical for adoption.

At any rate, these NSNs offer an opportunity for select DoD organizations (or perhaps Federal LE) to take advantage of the production contract associated with this program.

Griffin Armament Releases 3D Printed Optimus 6 Suppressors

Tuesday, June 3rd, 2025

Watertown, WI – May 30th, 2025–

Griffin Armament’s history with metal printed suppressors goes back to 2008 with prototype applications. We felt the technology was neither developed nor cost-effective enough to be viable and publicly accepted for a long portion of that time. The hope of more manufacturing applications in other industries being supported and costs of equipment reducing, as well as capabilities and technology increasing, were considerable factors in waiting for the technology to mature. Griffin’s Optimus® 6 is our first printed production suppressor. The Optimus® 6 is a powder metal additive manufactured 6mm capable suppressor optimized for the 5.56mm AR-15 platform. Complex internal baffle geometries were painstakingly prototyped and tested to yield a suppressor with low system backpressure and exceptional flash reduction.

The Optimus® 6 is constructed entirely of 17-4 H900 Heat-Treated Stainless Steel, and is available in three mounting variations: DUAL-LOK®, Griffin Taper Mount, and an industry-standard HUB (1.375×24 TPI) interface for use with HUB mount adapters. The printed baffle stack is welded to a machined rear housing that bears the serial number making warranty and repair work performable without the need to resubmit the lengthy Form 4 process for a new serial number. This is a problem with fully printed cans that hasn’t been adequately addressed in the market. A 1.73” outer diameter was chosen to allow increased internal volume – contributing to its sub-140 dB SPL.

Flash reduction is often seen as more important than sound reduction for military and LE applications, but both categories tend to suffer when creating suppressors with very low-restrictive baffling. The Optimus® 6 endcap was developed to address the inherent increase in flash signature coupled with LBP suppressors. This unique quad-prong end cap features complex internal and external flash-hiding geometries to bring highly competitive flash suppression to the LBP suppressor market. The Optimus® 6 is a thoughtful combination of traditional and new technologies yielding a low backpressure suppressor that is easily repairable, highly durable, at a reasonable weight, while exhibiting top of the line sound and flash reduction at a lower price than many other printed suppressors on the market.

“Making suppressors that have good acoustic performance, with a high quality to cost ratio has been important to Griffin over our 20 years in industry. We’ve seen the demand grow over the past number of years for suppressors that run more transparently to the firearm they are attached to- minimizing backpressure being one of the ideal solutions. Additive manufacturing has advantages and disadvantages that vary depending on the process. In some aspects, it improves the ease with which a geometry is created, and in others, there are limitations like low overhang angles that are impossible depending on the method used. We are happy to introduce the Optimus 6 to market, and to begin using additive manufacturing for some of our suppressor designs. The Optimus 6 is one of the most-performing 5.56mm cans I have used. One of the first customers to see the suppressor was a Law Enforcement department that liked the suppressor enough to place a large pre-order. Several of the people who I work with at Griffin were impressed with the suppressor and made the decision to make it their free suppressor for 2025, as one of our employee benefits is a free suppressor every year an employee completes with the company, if the employee wishes to take advantage of that benefit.”

Rugged Suppressors Contributes $40,000 to Support ASA

Sunday, June 1st, 2025

Travelers Rest, SC – The American Suppressor Association (ASA) is proud to announce that Rugged Suppressors has renewed its support for 2025 with a $40,000 contribution, reinforcing its deep commitment to protecting and advancing suppressor rights across the country.

“At Rugged Suppressors, we believe that suppressors have no place under the National Firearms Act,” said Michael Derdziak, CEO of Rugged Suppressors. “The ASA is the only organization with the focus, strategy, and drive to get them removed. We’re proud to support their mission and stand alongside them in the fight to protect the rights of responsible gun owners nationwide.”

Rugged Suppressors has built its name on uncompromising quality and innovation, producing some of the most durable and reliable suppressors in the industry. Their continued support reflects a shared vision with the ASA: a future where suppressors are treated like the hearing protection tools they are, not burdened by outdated federal restrictions.

“Rugged Suppressors has once again stepped up in a big way,” said Knox Williams, Executive Director of the ASA. “Their $40,000 contribution directly supports our work on Capitol Hill to remove suppressors from the NFA. Michael and his team understand what’s at stake, and they continue to lead by example. With their partnership, we’re able to push harder, go further, and stay focused on real policy change.”

B&T USA Files Federal Lawsuit Against SureFire, LLC Alleging Patent Abuse and Interference

Saturday, May 31st, 2025

Tampa, FL (June 2nd, 2025) – B&T USA, LLC and its parent company B&T AG of Thun, Switzerland, have initiated legal proceedings in the U.S. District Court for the Middle District of Florida against SureFire, LLC. The complaint seeks a declaratory judgment of non-infringement and patent invalidity and brings claims for breach of contract and tortious interference.

This action follows a series of unwarranted legal threats made by SureFire, which has sought to disrupt B&T’s lawful commercial activities by alleging infringement of U.S. Patent No. 7,676,976 — despite knowing that the underlying technology, B&T’s proprietary Rotex quick-detach suppressor system, was developed, publicly displayed, and sold to U.S. government end users years prior to SureFire’s patent application.

Despite clear evidence of B&T’s prior invention — including exports to the United States and documented use by the U.S. Navy — SureFire failed to disclose this information to the United States Patent and Trademark Office. This material omission calls into question the enforceability of the asserted patent and the good faith underlying SureFire’s conduct.

Moreover, B&T and SureFire had previously reached a mutual understanding: that B&T would not challenge SureFire’s patent so long as SureFire refrained from asserting it against B&T or its customers. SureFire’s recent actions constitute a clear breach of that agreement, forcing B&T to take legal action to protect its rights, its reputation, and its longstanding customer relationships. B&T has pursued every reasonable path to resolve this dispute privately and professionally. Unfortunately, SureFire’scontinued and deliberate actions have left no other choice.

“B&T has a long and well-documented history of innovation that predates SureFire’s patent by several years,” said Jon Scott Chief Executive Officer of B&T USA. “Despite having full knowledge of B&T’s prior invention, SureFire withheld critical evidence from the U.S. Patent and Trademark Office while using that same patent as a cudgel against not only us, but our partners. Our lawsuit seeks to hold SureFire accountable for this misconduct, to clear the record regarding B&T’s rights, and to ensure B&Tcan continue serving the defense and commercial markets without interference.”

Rampart Range Day 25 – Colt Canada

Wednesday, May 28th, 2025

Due to Canadian content laws, Colt Canada provides small arms to the Department of National Defence.

The Canadian military is currently working on an upgrade to their C8 carbines. Colt Canada showed off the latest version of their line of rifles, the C8 Modular Rail Ambidextrous Rifle in 5.56 NATO (Colt Canada also makes the MRR in 300 BLK).

It features a fully ambidextrous lower receiver with ambi bolt catch and release and well as fire selector switch.

This version with the 14.5” barrel is considered the general service variant and is intended for Combat Support and Combat Service Support personnel while close combatants will wield a carbine with an 11.6” barrel. As you can see, it is fitted with the Millbrook Strategic Sciences Multi Function Muzzle Device. The MFMD is timed and permanently affixed to the barrel and is currently already adopted by CANSOFCOM.

I had an opportunity to fire the 11.6 barrel version as well as a C20 sniper rifle in 7.62 NATO. Both were fitted with the MFMD. Although the MFMD is technically a two component system with a clip-on module which offers an additional 3db of attenuation, most don’t bother with the added weight. I was concerned that the carbine would feel unbalanced toward the muzzle but I didn’t notice it at all during firing. This is because most of the MFMD is mounted over the barrel and behind the muzzle. Additionally, although the device looks like a large block, most of it is hollow, filled with chases for the gas to run and escape.

This is a conceptual prototype of what a C8A4 might well look like. However, don’t surprised if the enabled change. For instance, DND still hasn’t decided on which suppressor and variable power optic they are going to field.

Departments, agencies, and military organizations in Canada can access Colt Canada and CZ Group products via Rampart.

ASA Lauds House Passage of the One Big Beautiful Bill, Including Removal of Suppressors from NFA

Friday, May 23rd, 2025

WASHINGTON, D.C. – Today, American Suppressor Association (ASA) President and Executive Director Knox Williams thanked House Republicans and Speaker Johnson for including the removal of suppressors from the unconstitutional NFA as part of the House reconciliation package that was approved this morning.

“Today, the House passed the One Big Beautiful Bill, including a provision that removes suppressors from the NFA. The removal of suppressors from the unconstitutional NFA tax scheme is long overdue and represents the biggest legislative victory for the Second Amendment community in my lifetime. It will benefit millions of law-abiding gun owners who simply want to protect their hearing while exercising their Second Amendment rights. Congressional Republicans are clearly keeping their promise to strengthen the Second Amendment and recognize the real need for these critical hearing safety devices.

“Passage of the One Big Beautiful Bill is a crucial step towards expanding Second Amendment rights in our country. As the President’s Big Beautiful Bill moves on to the U.S. Senate, we are confident the Senate will produce a final bill for the President’s signature that upholds citizens’ Constitutional rights. ASA continues its work with the White House and with House and Senate Leadership to get this bill across the finish line and further expand the Second Amendment for the American people.”
