Maxim Defense SDX RFLX SBR 300 Blackout 8.5" 30-Round Rifle

The Maxim Defense SDX RFLX is a semi-automatic 300 Blackout rifle built on the SDX platform, with an 8.5-inch barrel and the M-Kore reflex suppressor mounted over the barrel. The over-the-barrel design is intended to keep overall length short and balance close to that of an unsuppressed carbine, suited to shooters who want sound reduction and maneuverability in one self-contained system.

The rifle uses a tuned gas system and an internal suppressor extension to vent excess pressure. With subsonic ammunition, the manufacturer rates it at 129 dB at the shooter's ear. The receiver is finished in black Cerakote, and the rifle has a Maxim Defense stock and polymer grips, with a 30-round capacity.
