My weapon of choice any day.. Never got to shoot one.. That thing could toss a lot of lead quick.. Lugging ammo must have been a bugger tho. Need a pack mule..
The training I went through with it we never fired it standing from the shoulder but one faze of qualification was firing from hip with a sling.
Firing prone with bipod it was deadly accurate even firing full auto. There was no selector switch for full auto or single but with trigger control firing single shots on the 500 yard KD range it was most accurate.
It was my favorite weapon though hefty, IIRC around 22 lbs w/bipod.
