That is totally awesome.
After many years in the Infantry and firing a few M60's, just wondering how a semi would feel to fire. I'm assuming this will still be an open-bolt, or did I miss something somewhere? Reason I say this is that the M60 is like a flint-lock on the first round, you pull the trigger and wait.....and wait.....then it goes bang.
That's why it's so easy to get off single shots with a standard M60, you just pull and release, with the time-lag you're finger is off the trigger by the time the round fires and the op rod/bolt locks to the rear.
It's still the coolest thing I've ever seen, and wish I had one! What's next, an AT-4??? Now that would be cool.
