Sons of Liberty Gun Works .300 Blackout M89 WO Built Complete Upper Receiver Group - 9 In

Our in house Armorer, and SOLGW Armorer's Course graduate, has assembled these SOLGW uppers for your convenience and quality assurance.  Sons of Liberty Lifetime Warranty has you covered as well!

We've assembled these uppers from new-in-box inventory from our shelves.  All components are SOLGW sourced, including the "WO" marked Bolt Carrier Groups.  The BCGs undergo a 10-round high pressure test using SOLGW testing protocols:  (1) SAAMI proof round, and (9) regular pressure 5.56 rounds fired from full auto, in three magazines of three rounds each.

We offer this upper without a muzzle device, so the user can pick their preferred device.  When bought with a muzzle device, we offer free mounting and timing for your device.
