Here at TGR we are big believers in Ballistic Advantage barrels.  So when I started on a new 300 Blackout build I headed over to their website to spec out a Hanson Profile barrel.  Of course one of the key decisions surrounds matching the right barrel to the right handguard and gas block.  That is when I noticed the menu option for the Complete Uppers.  A Ballistic Advantage Hanson Profile barrel with a VLTOR Freedom Rail ready to rumble right out of the box?  Sold!

There were two 300 BLK uppers I was interested in.  The 8.3″ barrel with 7″ rail or the 10.3″ barrel with 9″ rail.  After some deliberation I decided on the 10.3″ barrel and placed my order and then stalked UPS anxiously waiting for delivery.

I was not disappointed.  Quality of build is outstanding.  I will post a full range report once I have time to run several boxes of subsonic and supersonic ammo through it.  For now, this is an overview of my build.  I have registered SBR lower receivers so no problem with length.

Suppressor:  Crux Nemesis 30 Titanium (rolled as Templar Tactical).  Precision Mounting System brake because it is SBR.

Bolt Carrier Group:  Fail Zero with EXO Nickel Boron Technology.  I used the Fail Zero BCG in my last 5.56 build and am very pleased with the performance, reliability, and how easy it is to clean even when running suppressed.

Vertical Fore Grip:  Mid-Evil Industries 360 degree.

Optics:  Trijicon MRO Miniature Rifle Optic.  Great situational awareness for hog hunting or home defense.  Can’t go wrong with Trijicon!

Lower Receiver:  Aero Precision.

Buttstock:  VLTOR.  I really like this system.  Solid.

Trigger Group:  Tac-Con 3MR.

This should be a sweet rig once it is built out and fine-tuned.  Primary uses will be hog hunting and home defense.

Quite honestly, I don’t spend a whole lot of time on the range during July and August in Texas.  It isn’t much fun unless you can get out early on a private range.  By the time the public ranges open it is already a furnace.  That said, I plan on getting this built and in use pretty quick because I’m excited to see how it performs with subsonic and supers.  Stay tuned.
