THUNDER BEAST MAGNUS K SUPPRESSOR - COMPACT .30 CAL RIFLE SILENCER, CB / SR / HUB MOUNT
The Thunder Beast Magnus K is the shortest suppressor in TBAC's Magnus lineup, built entirely from titanium and measuring just 5.5 inches on the CB and HUB versions. At 9 ounces and 1.8 inches in diameter, the Magnus K delivers sound reduction between a TBAC Ultra 5 and Ultra 7 (Gen2) in a package compact enough for hunting blinds and running PRS stages. It is rated for .30 caliber cartridges up to .300 Norma Magnum and is available in three mounting configurations: CB (TBAC taper mount), SR (locking ring, full-auto rated), and HUB (1.375x24, compatible with Dead Air Key-Mo, SilencerCo ASR, Q Plan B, Xeno, and direct-thread adapters). A 360-degree fully-welded titanium baffle core delivers the consistent POI repeatability that TBAC is known for. The Magnus K is also available in .338 and .375 caliber by custom order.
Three mounting systems cover different use cases. The CB version runs TBAC's taper mount, shared with the Ultra 5, 7, 9, and Dominus-CB, making it the most straightforward option for existing TBAC users. The SR adds a locking ring mechanism, brings the length to approximately 6.2 inches and weight to about 11.9 ounces, and is the only Magnus K variant rated for full-auto fire. The HUB version opens the suppressor up to virtually any third-party QD ecosystem via the 1.375x24 thread pattern. For more suppression in a similar footprint, the Magnus S adds 1.4 inches with a meaningful step up in sound reduction. The full-size Magnus at 9 inches is the top of the lineup.
CAPITOL ARMORY'S OPINION
The Magnus K fills a specific role and does it well. If you are running a bolt gun for PRS or hunting and do not want to deal with the added length of a full-size can, this is a serious option, not a compromise. The 1.8-inch diameter gives it a meaningful internal volume advantage over other K-length suppressors that use a narrower body, and the sound reduction shows it. You are getting real suppression here, not just flash and blast reduction.
The CB version is the cleanest setup for most shooters already in the TBAC ecosystem. If you want mount flexibility across different hosts or QD systems, go HUB. If you need full-auto capability, the SR is your only option in this lineup and it is the one to buy without hesitation. The 100% titanium construction keeps weight honest across all three versions, and TBAC's fully-welded baffle core is the reason this can holds zero better than most of its competitors.

THE ULTRA-COMPACT MAGNUS K
The Thunder Beast Magnus K is a full-titanium silencer designed for suppression with a very small footprint. At 5.5" long, it's an exceptionally compact silencer best suited for those who need to quiet down their rifles but can't add much additional length. Thanks to the additional volume from the 1.8" diameter, the TBAC Magnus K suppresses better than others in the sub-6" category.
Although the Magnus K can fit many roles, it's ideal for long-range precision shooters and hunters. The compact size reduces the report to a manageable level while keeping the size as small as possible. This allows for quick maneuvering of the rifle, either on the PRS circuit or inside a hunting blind. For those wanting a compact size with a bit more suppression, check out the Magnus S. If that's still not enough, give the full-size Magnus a look.
Shooters have different preferences when it comes to mounting solutions. The Magnus K is available in TBAC's tried-and-true CB (or compact brake) version, their new and more robust SR variant, and the versatile HUB pattern. The HUB version allows for numerous direct-thread solutions to be utilized, as well as nearly a dozen third-party mounting systems to be installed quickly and easily.
