We’ve made a dedicated 6mm/.243 cal version of the SPIRO. This version is designed around the 6 ARC cartridge, but can also accommodate .243WIN and 6 Creedmoor. Its ideal application is a 6 ARC AR-15 with a 12.5-18″ barrel (ie, SBR and SPR/DMR type setups). It will be available to order in either direct thread (5/8-24) or HUB configurations. SR mount versions should be available sometime later this summer.
The SPIRO 6mm is available to order now and the first units should be at dealers in approximately 10 weeks.
The SPIRO is our new low back pressure suppressor, designed to have extremely low back pressure (measured and verified with instrumentation) but also very good suppression levels, so you don’t have to choose between having a quiet can or a low back pressure can.
