Introducing the SDX RFLX SBR-a new evolution in integrally suppressed weapon systems from Maxim Defense. Chambered in .300 Blackout and built on the battle-proven SDX platform, the RFLX features Maxim’s M-Kore reflex suppressor, a true over-the-barrel system that reduces added length while maximizing sound reduction and balance. With a tuned gas system and internal suppressor extension, the SDX RFLX delivers a stunningly quiet 129 dB at the shooter’s ear with subsonic ammo-making it one of the quietest compact .300 BLK rifles in its class.
