Description

SLR MFG 5" 300 Blackout

Includes Barrel, Straight Gas Tube & Jet Gas Block with Hardware

   

  • 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.
  • 11.7oz weight

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.

Recommended Buffer and Spring:

H3 Buffer

Carbine Spring

    Worth the money

    The only problem is that once people see and hear it, they're going to ask you to build one for them too.

    Micro 300blk Barrel

    This barrel sticks to the old adage of “You get what you pay for.” The fitment into the upper was perfect, the gas tube and block are flawless with 0 machine marks. Pistols cycles with 0 issues shooting super sonic or suppressed with subsonic rounds. Groups are on point. If you’re even close to just being on the fence, buy it. You will not be disappointed.

    Gorgeous and compact. These don't come by often but pick it up once they do.
