Here at SIONICS, we test fire EVERY BCG, upper receiver group, and firearm.
Our test firing process is simple:
- BCGs get 5 rounds of M193 and another single round in a separate magazine to ensure function, ejection pattern, and lock-back.
- All upper receiver groups and firearms get 7 rounds of M193 and another single round in a separate magazine to ensure function, ejection pattern, and lock-back.
