11 year old girl completely field strips her AR15 and then reassembles it in 53 seconds total. However she makes the following three errors (only our readership would know):
1. Failed to clear the weapon prior to disassembly (a major safety violation)
2. Failed to make sure the 3 gas rings on the bolt were offset
3. Failed to perform a function check with the weapon on safe
Still very impressive as just the charging handle is a pain in the butt by itself.
