Ok another great Carbine class is in the book.
We had one AK and one weird Beretta thingy.
Quite a few self induced malfunctions not the weapons fault.
Here are my notes.
BCM intermittent failure to fire I think something was up with the bolt.
PSA Not doing good several malfunctions of various types.
Anderson couple failures to extract.
The AK was 100%!
Notes
Know the manual of arms for the AR.
Slap and pull on the magazine
After reloading release the bolt
Know how to use your sling when switching from strong side to weak.
I think it's foolish to just trust something because it supposed to be top of the line, or known to be very reliable.
Find out if your rifle is going to run or not. If it fails fix it until it does run properly.
