Just what the doctor ordered - R&D Precision Full Auto BCG

Dr. Funkenstein's Review of R&D Precision Full Auto BCG
I recently built a budget AR-9 and I decided to check my split times with it and they weren’t as fast as I liked so I modified the existing bolt but then needed to shout hotter ammo to maintain reliability. This bolt is what I should of started with, not only did improve my speed and accuracy but it runs with any ammunition
