The Mission

When creating the PR series of silencers the goal of Otter Creek Labs was simple – create a silencer optimized for long range shooting and competition that performs better and offers the same or better features than other popular precision rifle silencers at a more affordable price… We’re very proud to say we’ve achieved that!

Features and overview

  • Designed specifically for long range precision rifle shooting and competition with substantial recoil reduction, minimal POI shift and has shown slightly improved accuracy on all rifles during testing.
  • Constructed of titanium with a 17-4 H900 heat treated blast baffle to ensure a long, erosion free life even when running direct thread.
  • Threaded 1.375×24 industry standard “ASR” threads the PR30L gives you the ability to use mounts from area 419, EA Thunder Beast adapter, SilencerCo, Griffen, Dead air, Torrent, Q, YHM and many more. The possibilities are endless and you’re not confined to one companies proprietary mounting system.
