I guess you have never been afflicted with African troops/rebels, if they can break it, they will. The only gun that can survive their handling/mistreatment is the AK47.

The theoretical problem associated with closed-bolt operation has always been that of "cook-off." When barrel temperatures greater than 250 degrees Centigrade are maintained for more than a minute, premature ignition of a cartridge in the over-heated chamber becomes possible. There has been some speculation about the MP5 in this area. |
I agree with you, firing from a closed bolt is inherently far more accurate then firing from a open bolt. Personally I have always found that the Sterling to be more then adequate when fired repetition or bursts.

The "cookoff" problem is more theoretical than practical and the gun is , indeed, easier to shoot well under stress than a typical open-bolt operated smg. |
I can fully understand that the gun is easier to shoot from a closed bolt. There has been a lot of discussion over the years regarding cook-off, some say impossible, other not. I would still be very cautious regarding cook-off.
Interesting subject.
