We will continue to gather this information to assist our customers in making informed buying decisions, and will keep our website current with the latest information.

Guaranteed. Forever.®

We make purchasing and returning products as simple as possible. If you buy a product from Brownells and decide you don’t need it, don’t want it, or just don’t like it, we’ll take it back any time… with a few exceptions

Guaranteed. Forever.

Guaranteed. Forever.® return policy applies to the product’s original owner along with proof of purchase. Any items returned within 45 days of shipment are entitled to a refund. Any items returned after 45 days of shipment will be issued store credit in the form of a Brownells Gift Card.

Manufactured in the US with the highest quality components, the BRN-15 Upper Receiver Groups are great starts for your next build. Pick your preferred bolt carrier group and charging handle to complete.

The BRN-15 Upper Receiver Groups feature a 5.56x45mm NATO chambered, nitride finished barrel, available in several popular lengths. Models are available in a Government, medium profile barrel, with the 16 inch also available in a lightweight contour. Barrels feature a gas block dimple, that the rear gas block screw securely engages. All barrels are stress releived.

Unique MLOK handguard extends past the gas block, to provide as much usable real estate as possible. Anti-rotation tabs at the rear of the handguard engage the upper receiver, preventing any cant in relation to the receiver picatinny rail. Large dual screws clamp and pass through the properly torqued barrel nut to ensure the handguard will not slip forward. Large vents are placed towards the rear, to allow both the barrel and handguard to cool more rapidly.

Forged Mil-Spec type upper receiver features M4 feed ramps, ejection port cover and forward assist. Forward assist pin is knurled at the front, to ease future swaps.

  • 4150 CMV (Chrome Moly Vanadium) Barrel

  • 1/2-28 Muzzle Threads
  • A2 Flash Hider
