Description

 

  • 5″ – 300 Blackout caliber
  • 4150 CMV
  • Melonite Finish
  • 5/8-24 Thread
  • Jet Gas Block with set screws and roll pin
  • Custom length straight gas tube with melonite finish
  • .750″ Journal barrel pre dimpled under gas port
  • Gas port and block optimized for function with or without suppressor for all Supersonic bullet weights.
  • Gas port and block optimized to run subsonic loads with a suppressor
  • Subsonic loads without suppressor are not recommended. Function may or may not be reliable as 300BLK Subsonic loads were/are not designed to run without a suppressor.

Note- MLOK and Keymod Handguards are compatible with this assembly. Mlok nuts will clear Handguard directly under gas block.

Note- For Suppressed or Traditional muzzle devices use a 4.25″ Handguard  (Receiver to muzzle shoulder distance is 4.3″) or up to 5.0″ Handguards if no suppressor to be used. ( Receiver to muzzle end is 4.95″)

Note- For Linear Comps use a 5.5″ to 6″ Handguard. Generally we use a HG 1/2″ longer than the barrel.

Note- Usually H to H3 buffers are used. For PDW stocks we have used the JP Std and Heavy types both seem to work the same.
