Thunder Beast Arms Corporation's new 338 ULTRA SR suppressor is the company's first suppressor to feature its new SR mount. The company says the SR, or secondary retention, mount has been in the works for four years and was selected by Accuracy International for its 2017 US SOCOM Advanced Sniper Rifle (ASR) contract submission. The SR mount is a quick detach mount that maintains the accuracy and repeatability standards TBAC is known forand adds a rotation, locking collar that provides secondary retention for the can. The SR mount acts as a secondary, fail-safe, locking mechanism that locks the suppressor to the muzzle brake. The mount's course threading reduces the number of turns required to mount the suppressor. From Thunder Beast: The SR mount uses a novel paw and cam-path system to ensure that happens in either of the two adjacent detent slots for any shouldering position of the suppressor on the conical brake shoulder. This eliminates the off-by-one problem that many ratcheting mounts have. The SR mount has the exact same accuracy, repeatability, and return-to-zero characteristics that all our precision suppressors are known for. The ULTRA series is constructed of titanium with a fully-welded core. This material and construction provide a great strength to weight ratio. It can take whatever your precision rifle can dish out. The 338 ULTRA SR was designed around .338 Lapua Magnum for maximum flexibility and is rated with that cartridge down to 16-inch barrels. The 338 ULTRA SR can easily do multiple-rifle duty on 6mm's, 6.5's, .260's, .308, and most .30 caliber magnums.
