NBS 14.5" Mid-Length 5.56 NATO 1:7 Complete Upper w/ Front Sight Base
Out of stock
This is the next release in our line of NBS Complete Uppers. We like to think of it as the ultimate truck gun. We build a lot of ARs and our favorite’s, the ones that we like the most and perform the best are the ones we decide to sell (and yes there are more coming). This is an example of that. We love this configuration and it fits right in with our no bullshit approach. It is built on an Aero Precision Upper Receiver with a Nitride Ballistic Advantage Government Profile 14.5″ barrel paired with the excellent NBS Black Nitride BCG. Racking is facilitated using a Strike Industries Extended Latch Charging Handle. And if you haven’t handled a rifle with this Magpul SL Handguard, you’re missing out. We love a beautiful free-floated rail as much as the next guy but this thing is just so solid and so comfortable in the hand. We topped it off with one of the best hybrid muzzle devices you can get, the VG6 Precision Epsilon. This thing tames recoil and muzzle rise with the best of them plus it is pinnable which makes it 16″ overall for use in restricted states.

Please note: As with many other top of the line 14.5″ mid-length uppers this is one of the smoothest shooters around but it does prefer quality ammo . If you feed it underpowered (the cheapest of the cheap) ammo you may experience some short stroking. Any mil-spec powered ammo will be fine but if you want to shoot the cheaper stuff (no judgement), we recommend lightening the buffer weight. The KAK Configurable Buffer is perfect for that.
All NFA/ATF Rules Apply: You may use this barrel with a lower receiver that is a Registered SBR, Machine Gun, or Pistol. Possession of this barrel paired to a Non-NFA lower receiver is Prohibited, except when permanently attaching a muzzle device extending the length to 16 inches.
