17 Design & Manufacturing has recently teamed up with Brownells in the exclusive launch of the IFLR-10 or Integrated Folding Lower receiver based on AR-10 pattern.

Brownells states “Introducing the Brownells exclusive IFLR-10 (Integrated Folding Lower Receiver).

The 17 Design & Manufacturing IFLR-10 Stripped Lower Receiver is the perfect base for your AR 308 build.

The IFLR-10 has the folding mechanism machined directly into the lower receiver.

All wearable parts are made from S7 tool steel which leads to extreme wear resistance and corrosion resistant coatings ensure your IFLR stays mint for years to come.”


  • Upper tensioning screw- allows user to fine tune the fit of the upper and lower through the use of a nylon tipped tensioning set screw in the grip tang of the receiver.
  • Flared magwell angle- Wider angles in the magwell allow a more flared feel without increasing the width/footprint of the lower receiver.
  • Features a threaded bolt catch pin.
  • Comes with Specialty H1 Buffer, nylon tipped set screw, and assembled IFLR in stripped lower configuration ready for your custom build.
