ECHOCORE Sector 5.56 FS BLK Rifle Suppressor
The Sector 5.56 FS is among the quietested 5.56 silencers we've tested — optimized for SBRs and battle rifles that demand top-tier sound and gas control. Its long-form Inconel body and XCR baffles reduce blowback, recoil, and flash, keeping short-barreled rifles cleaner, cooler, and quieter through sustained fire.
