UBAR Lower Receiver Hardware Kit

(8 reviews) Write a Review

Product Overview

So you want to build the strongest 3D-printable AR-15 lower receiver? Here's the hardware kit that you need. 

  • includes U-bolt, front and rear takedown pins, pin retaining clips, self-tapping grip screw, and the special front eye bolts/ nuts
  • just add your lower parts kit like any other stripped lower
  • The front eye bolts are a very specialized piece of hardware that isn't really availible in bulk, thus the higher kit cost.

    I don't care if I am a grown man, I'll never not giggle excitedly when I get Jolly Ranchers and stickers included in my gun parts kit. The kit is great btw. 5/5 would give Bobby more pets again
