What is the 17 DESIGN AND MANUFACTURING - AR-15 Lower Receiver, Billett, Multi-Cal?

The 17 Design & Manufacturing AR15 Stripped Lower Receiver is the perfect base for your AR15 build. Machined to mil-spec dimensions, their lowers work with standard AR15 components and ensure the highest quality and parts interchangeability.

Additional features:

  • 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.

17 Design AR Lower
I bought 2 several months ago. I built one soon after picking them up from gun store. Very happy thus far ...no complaints. It fit nicely with billet upper I had, that I used for the upper build.

Great lower - great price
I built a very nice, reliable lightweight rifle, (wifle), with one of these about a year ago. You can't touch a billet lower for this price anywhere. It has a nice finish with good anodizing, and really does look great. Just beware that 17 Design is out of business, but with Brownells and their ironclad lifetime guarantee, I wouldn't worry about it.

Good value
I have purchased several of the 17 design and manufacturing lower receivers. One for a .223 Wylde rifle and one for a 7.62x39 pistol. They both have been a breeze to assemble.

17 Design Lower
This is my second 17 Design lower. I do not have much more to add to my first review. I have noticed several writers have commented on having issues with the bolt stop catch. They said it did not sit straight, leaned right or left. I have been using Strike Industry bolt catches in my ARs. Including my last two 17 Design lowers. I have not experienced the problems the other writers noted. Also they could try using a tension pin ( roll pin ) instead of the supplied threaded pin. This may give them a tighter fit. This is a 5 STAR lower and a great value.
