Maxim Defense Industries

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. Features : - Includes Magpul CTR Stock - SDX 2-Piece M-LOK Handguard - Enhanced MIL-SPEC Lower Receiver Parts & Components - 129 dB at Shooters Ear with Subsonic Ammunition - Full Auto Rated
