Featuring a suppressor locking mechanism four years in the making, the new 338 ULTRA SR from Thunderbeast offers a quick-detach capability that is repeatable. As explained by Ray from Thunderbeast in the above video, the primary difference on the new can is an innovative suppressor locking mechanism that is “bank vault tight” and offers secondary retention (hence the “SR” designation).
The SR mechanism is designed to reduce the number of turns needed to mount the suppressor.
Chambered in .338 Lapua Magnum/.338 RUM, the 20-ounce device is crafted from titanium and has a fully-welded core. Some 11-inches long, the body is Cerekoted in a range of four different finishes– Black, OD Green, FDE, and SURG Brown. TB advises their suppressor will drop the sound on a .338 LM to 135-138 dB at the muzzle with little first round pop.
The 338 ULTRA will be offered for sale starting Jan. 22, the first day of SHOT Show, with an MSRP of $2195.
