Description

The BRN-16A1® Complete Upper Receivers are back!


Styled after the issued U.S. M16A1, the BRN-16A1® has distinct features, found on late 1960s M16 rifles.

The muzzle of the BRN16A1®, is capped by the classic A1 flash hider, with ports around its radius, and is retained by a proper split washer. The flash hider is attached to a lightweight 20 inch barrel, found on AR-15 variants through the M16A1.

Available with a 1-12 or 1-7 twist. Select 1-12 if shooting 55gr bullets, and 1-7 if shooting 62gr or heavier. The front sight base is not F-marked, meaning the round, tapered front sight post is properly in line with the carry handle rear sight. The black triangle handguards closely emulate the original M16A1 handguards. A flat slip ring is at the end of the 5.56x45mm NATO barrel assembly.


Mounted to the upper is a proper ejection port cover, with a flat external "bump" (not just an off the shelf A2). The receiver is the proper M16A1 style, with a forward assist but no shell deflector. The rear sight is the standard A1 aperture, that can easily be adjusted with a cartridge or tool. Included bolt carrier group is the proper manganese phosphate mil-spec BCG, with chrome lined interior.



Key features of the BRN-16A1®:

  • M16A1 upper receiver without shell deflector
  • 20" 5.56x45mm NATO barrel with 1-12 or 1-7 twist & chrome bore & chamber
  • M16A1 ejection port cover
  • Tear drop forward assist
  • A1 rear sight assembly
  • A1 black polymer handguards with heatshields
  • Manganese phosphate mil-spec bolt carrier group with 9310 bolt
  • A1 flash hider

We actually tracked down the original company that manufactured the Colt® AR-15 optics of the 1970s and asked them to build a new one for us as close to the original as possible - right down the yellow inspection stickers. The Retro 4x Optic has updated technology under the hood, with modern lenses and construction. The result is a scope that looks just like the original but has optical clarity and performance that are head and shoulders above it.

  • Attaches to any standard AR-15/M16 carry handle
  • Fully Multicoated lenses are fog and waterproof
  • BDC click-adjustable elevation turret
  • Manufactured in Japan with high quality internals and lenses

The Retro 4x Carry Handle Optic sports a simple, intuitive fine duplex reticle, like the original, and an elevation turret with BDC (ballistic drop compensated) clicks that closely match modern .223/5.56 55gr and 62gr ammo. As its name indicates, the Retro 4x comes with an integral carry handle mount that easily attaches to most AR-15 carry handles - no tools required.

As with all products we sell, this scope is fully backed by our Forever Guarantee.
