KP-15

The top questions Hoffman Tactical gets asked:

0:56 – Why not print with the stock and pistol grip integrated into the lower receiver (like the KP-15 Polymer receiver)?

Different techniques discussed for making lower receivers:

7:07 – Metal casting

9:36 – Using a forged carbon fiber using 3d printed molds

11:00 – Salt remelt method

13:04 – Printing a low infill 3d printed part and filling it with epoxy

14:57 – Where do I find the files?  See the Print Shoot Repeat video on the topic + Hoffman Tactical‘s website.

17:08 – How many rounds do 3d printing firearms last?  Hoffman says he has just over 1000 rounds on his personal 3d printed AR-15.

21:10 – What is the hose clamp for, and why do you use it?

I really enjoy how Hoffman puts a lot of thought and consideration into everything.
