Brownells 75th Anniversary - A Shooting Heritage

A Cutting-Edge Upper for Your AR-15

Over the last few years, manufacturers have settled on a number of key features that make their rifles stand out in the marketplace. Unfortunately, few companies blend all these elements into a single design, so Brownells and Midwest Industries partnered to bring all these enhanced components into one product: the AR-15 SLH M-LOK Assembled Upper Receiver.

These AR-15 SLH M-LOK Assembled Upper Receivers are the latest in AR design, featuring a slim, streamlined handguard compatible with all M-LOK accessory attachments. The system is also built with a mid-length gas system designed to reduce wear on internal components as well as mitigate recoil, and the Pencil-profile barrel features a .223 Wylde chamber that enables users to get the most accuracy possible from their 5.56 NATO and .223 Rem. ammunition.

  • Receiver forged from 7075 aluminum
  • Twist rate: 1:8 inches
  • Made entirely in the USA
  • Matte-black finish
  • Does not include Charging Handle or Bolt Carrier Group

Other features found on the AR-15 SLH M-LOK Assembled Upper Receiver include M4-style feed ramps, A2 flash hider and an all-black finish.
