The reviewer, Chris from Honest Outlaw, details initial reliability issues that were resolved by adjusting the gas block. He compares the 338 Arc to 300 Blackout and discusses its potential as a quiet, powerful option for home defense or as a truck gun, despite its higher cost and limited niche.
This video tests three subsonic 300 Blackout ammunition types (Federal 220gr, Hornady SubX 190gr, Hornady Black 208gr AAX) with a Sig Sauer Rattler LT and Surefire 300 SPS suppressor. It evaluates grouping size, noise, and flash suppression, noting the importance of an open-tine muzzle device for suppressor compatibility and the Rattler LT's 1:5 twist rate for stabilizing subsonic rounds. The Sig lower receiver proved more reliable than a conversion kit.
This video explores modern lever-action firearms, showcasing their versatility in both competition and trick shooting.
