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.

Had everything I needed, came quickly and was a reasonable price! TY RK
high quality parts, fast shipping, Free candy.
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
High quality parts, fast shipping, and it even came with a sticker and candies. Couldn’t ask for better.
The kit is legit!
Everything is there and screws fit nicely
Spoke with RK directly about some questions. Immediate response as well as some guidance of availability. Definitely recommend and will be coming back for all my parts needs. Ubar parts kit was shipped quickly and all parts are there for your build
