For those looking for a cost effective 13.7" upper that is still packed with quality features, these URG's are just for you! To speed things up, we're simplifying the selectable options and only offering a few different configurations. These uppers will either have the muzzle device permanently attached to reach the legal 16" length to be considered a rifle or come with no muzzle device. These URG's are made to order, so please allow for up to two weeks for your order to ship.
In order to streamline the assembly process, no parts substitutions will be accepted outside of the selectable options.
All NFA Rules and Regulations Apply. All Federal, State, and Local Rules and Regulations Apply.
Note from Phillip: For those who are concerned about concussion with Dead Air KeyMo Brake, a suppressor with a KeyMo adapter or the Hansohn Brothers Blast Diverter with KeyMo Mount is what I recommend.
The Ballistic Advantage 5.56 chambered 13.7inch Government Profile Mid-Length Modern Series Barrel (BABL556033M) is machined from 4150 Chrome Moly Vanadium steel with a QPQ Corrosion Resistant Finish and QPQ coated M4 feed ramp extension. All barrels will be dimpled and have their feed ramps polished. Feed ramps will also be contoured to match the upper receiver if necessary.
Our very own eXcise Optimized Handguard is packed with practical features while keeping overall weight reasonable. Perhaps most notable, yet oftentimes overlooked feature by other companies, is the nitrided steel reinforced QD sling sockets.
Aero Precision's Mil-Spec Forged Upper Receiver.
Your choice between a standard and adjustable gas block. If running a suppressor, we highly recommend choosing the adjustable gas block option.
- If you like the factory gas port size of the Ballistic Advantage barrel and do not want to run an Adjustable Gas Block, the Low Profile Gas Block option is for you.
- If you want the highest quality AGB on the market that also has the option to bleed-off gas as well as restrict it, the Superlative Arms AGB is our personal choice and recommendation.
Your choice of either a Mil-Spec 304 stainless steel gas tube or a Black Nitrided 304 stainless steel gas tube.
Your choice of muzzle device between the Dead Air KeyMo Brake or no muzzle device. Choose the option that suits your needs best and is legal to use in your area. The Dead Air KeyMo Brake will be permanently attached to barrel to meet legal 16" rifle length.
Option to add a Radian Raptor or Aero Breach ambidextrous charging handle.
