Product description

Turn a Standard Blowback AR9 Into a Modular SD-Style Suppressor Host

Features

  • 4.3″ ported 9mm barrel with a 1:10 twist rate
  • Ported barrel system is designed to reduce projectile velocity before the suppressor
  • Designed for compatible traditional blowback AR9 uppers using standard AR-pattern barrel and barrel-nut dimensions
  • Includes both 1.375×24 Bravo/HUB and 1.125×28 Alpha suppressor mounting modules
  • Integrated taper interface seals the barrel and shroud assembly without an O-ring
  • Can function without a suppressor as a forward-blast diffuser and linear compensator
  • Shroud assembly measures approximately 5.2″ from the receiver face with the HUB module or 4.92″ with the Alpha module
  • Current-production tube is Rocksett-bonded to the taper adapter from the factory
  • Black nitride finish

The Novox Research X-SD replaces a standard AR9 barrel with a 4.3″ ported barrel and integrated shroud system designed around SD-style suppressed operation. Gas is vented through the barrel ports before the projectile exits, reducing velocity while the included Alpha and HUB modules allow the system to accept a broad range of compatible 9mm suppressors. Its modular mounting system avoids locking the build into a single suppressor thread standard.

Note: Suppressor is not included. The barrel-to-taper-adapter threads are proprietary and are not M18. Verify barrel nut and handguard clearance before installation; Novox specifies a maximum barrel-nut length of 2.24″ and an assembled outside diameter up to 1.27″ with the Alpha module or 1.5″ with the HUB module. This 4.3″ barrel may create an NFA-regulated short-barreled rifle when installed in certain stocked firearm configurations.
