THUNDER BEAST MAGNUS S SUPPRESSOR
The Thunder Beast Magnus S (MAGNUS-S) is a mid-length version of TBAC's flagship Magnus suppressor line. At 6.9 inches (CB version), it sits between the compact Magnus K (5.5") and the full-size Magnus (9.0"), offering sound reduction between the TBAC Ultra 7 Gen2 and Ultra 9 Gen2 in a lighter package.
TBAC engineered the Magnus line for maximum sound reduction. The larger 1.8-inch diameter provides more internal volume than traditional precision rifle suppressors, producing lower sound levels across calibers from .223 up to .300 Norma Magnum. The all-titanium construction keeps weight under 11 ounces on the CB and HUB versions.
Three mounting configurations are available. The CB (Compact Brake) version uses TBAC's traditional taper mount shared with the Ultra 5, 7, 9 and Dominus-CB suppressors. The SR (Secondary Retention) version adds a locking ring mechanism and is the only Magnus S variant rated for full-auto use. The HUB version features a 1.375x24 thread pattern compatible with third-party mounts from Dead Air, SilencerCo, Q, Griffin Armament, and others.
The Magnus S is available in .30 caliber (rated to .300 Norma Magnum). For .338 or .375 caliber versions, contact Capitol Armory to place a custom order.

A LITTLE BIT SMALLER MAGNUS
The Thunder Beast Arms Magnus S is an all-titanium suppressor for those who value sound suppression, weight savings, and a smaller suppressor on the front of their rifle. The 6.9" long Magnus S has a similar footprint as many mid-size suppressors, but thanks to the extra diameter, it can perform with many much longer.
The Magnus S is a great size for all-around use. It's right at home on the range, in a hunting blind, or during a PRS match. Many suppressor owners will find the Magnus S is the "just right" size for balancing sound signature reduction and compact size. If you want absolute decibel reduction above all else, the Thunder Beast Magnus (full size) is an option, and if the S is still a bit too long, TBAC's Magnus K is merely 5.5" long.
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.
