THUNDER BEAST MAGNUS K-RR SUPPRESSOR
The Thunder Beast Magnus K-RR (MAGNUS-K-RR) combines the compact Magnus K suppressor body with an integrated Reduced Recoil (RR) endcap brake. The result is over 60% recoil reduction on .300 Winchester Magnum compared to a bare muzzle, nearly double the 29% reduction of a standard Magnus with flat endcap.
The "K" designation indicates the shortest Magnus length at 5.5 inches base. The RR brake adds approximately 1.5 inches and 2.4 ounces, bringing the CB and HUB versions to 6.9 inches overall and 11.5 ounces. Sound suppression falls between the TBAC Ultra 5 and Ultra 7 Gen2, with the RR endcap measuring approximately 10 dBA louder at the shooter's ear than the flat endcap version due to the brake ports.
Four mounting configurations are available. The CB (Compact Brake) version uses TBAC's traditional taper mount shared with the Ultra series and Dominus-CB. The SR (Secondary Retention) version adds a locking ring mechanism and is the only K-RR variant rated for full-auto use. The HUB version features a 1.375x24 thread pattern for third-party mount compatibility. The BA mount is available for .338 caliber only.
The Magnus K-RR is available in .30 caliber (rated to .300 Norma Magnum), .338 caliber (BA and SR mounts), and .375 caliber (HUB mount only).

RACE READY AND COMPACT!
The Thunder Beast Magnus K-RR is built for shooters who want serious recoil control in a compact, lightweight suppressor. The "K" stands for the shorter model, and “RR” means “Reduced Recoil” or “Race Ready”—a nod to its integrated rear brake that helps tame even hard-hitting rounds like .300 Win Mag. At just under 7 inches and weighing about 11.5 ounces, it’s surprisingly effective for its size, offering excellent sound suppression for such a compact can.
Whether you're running a PRS match or hunting in close quarters, the Magnus K-RR keeps you on target with less kick and plenty of control. Capitol Armory keeps the .30 caliber CB version in stock, but we’re happy to special order other variants—just give us a call and we’ll get it handled.
