Headspace and Timing

[Stan]

You guys still don't have the Fabrique Nationale Herstal quick change set that eliminates the headspace issue?

IIRC four of five such sets were developed decades ago by different companies, even including U.S. companies.

What`s your military budget? Half the world's military spending?
Still suffering from a 1919 machine gun design flaw???

Fuchs,
In principle the design seemed to be good and the E2 versions tested at APG, MD puportedly saved 10 minutes on a hot barrel change. But, most of us that trained and regularly qualified with the M2 can perform an HST (or HS&T) in less than a minute. The differences in barrels are ever-so-slight, that a seasoned marksman can be up and firing in less than a minute.

There are a number of issues that Global Security doesn't cover at the link such as Safety of Use Messages (SOUM) 06 and 07 from TACOM (AKO login required).

In short, and much like most SNCOs believe, this seems to be a training deficiency combined with money-hungry companies than a problem with the BMG.

I'd say keep it simple (KISS)

Going by feel is always a bad idea though it will work.

Yep, concur. Then there's this...

Spin the barrel in and back off two clicks.
A dime and a nickel can be used as field expedient gages.

And for timing you would then use what?

How many E-1s have a dime and a nickel at the end of the month?
