Someone at ACC accidentally fired four rounds from a M4 into their blank firing adapter, in order to test …

It is good to know that they are able to contain real bullets in the event of an accident.

UPDATE: It was no accident. My apologies to AAC for incorrectly stating that. John from AAC emailed me and said …

When we made the BFA, part of the requirement is that the BFA be able to take a number of live rounds without losing integrity and causing injury should someone accidently fire live ammunition with a BFA in place.

The four rounds were fired as proof of concept to show that it did what is was supposed to do. Which it did.

We than EDMed the BFA open to study the results.
