Maxim Defense SDX508 SBR: Integrally Suppressed 300 Blackout Rifle
The Maxim Defense SDX508 SBR (MXM-49218) is a high-performance, integrally suppressed Short-Barreled Rifle chambered in 300 Blackout. This factory-configured SBR features an 8.5-inch barrel paired with Maxim’s advanced Arid RLFX reflex suppressor, delivering outstanding sound reduction in an extremely compact package. Designed for professionals who require maximum performance with minimal signature, the SDX508 combines cutting-edge suppressor technology with the proven reliability of the 300 Blackout platform.
Maxim Defense engineered the SDX508 with a focus on reducing overall length while maximizing sound suppression. The RLFX reflex suppressor system allows a portion of the suppressor to extend over the barrel, resulting in a much shorter overall weapon length compared to traditional suppressor setups. Finished in a professional Arid (desert tan) color, this SBR is optimized for operations in arid and desert environments while maintaining a low visual signature.

Why Choose the Maxim Defense SDX508 SBR
The Maxim Defense SDX508 SBR stands out as one of the most advanced integrally suppressed 300 Blackout rifles available. Traditional suppressor setups add significant length and weight to a firearm. The SDX508 overcomes this limitation through its reflex suppressor design, allowing part of the suppressor to sit over the barrel. This results in a dramatically shorter overall length while still achieving exceptional sound and flash reduction.
Chambered in 300 Blackout, this SBR excels with subsonic ammunition, offering near-silent performance when paired with the right loads. The Arid finish makes it particularly well-suited for operations in desert and arid environments. Maxim Defense’s reputation for building duty-ready, high-quality firearms ensures the SDX508 meets the rigorous standards expected by military, law enforcement, and serious civilian users who demand reliability in extreme conditions.
