ref the 50 BMG M-2 barrel..yes you can, but given the choice between the
standard M2 barrel and the aircraft M2 barrel, get the aircraft barrel as it is
a bit lighter in weight.
But regardless of which you get..GET AN UNISSUED ONE... These military barrels
are decent, but I would sorten them about 1/4" on the chamber end and then use
a "target" 50BMG reamer to bring it back up as the throats of the military
barrels are a bit long to accomodate all bullet configurations that may be
fired through a MG...while this is A-OK on full auto..for aimed fire, a long
throat is not that great for your grouping...
Hope this helps..

There are a couple of places you can actually buy plans to do so.

Browning M2 machine gun barrels have been used to make bolt
action single shot rifles. You should realize that the chambers
of machine gun barrels are "generous" and the bores aren't made
to exceptionally tight tollerances so they probably won't
deliver match accuracy. If you go to the expense and effort
to machine a safe receiver and bolt and get them properly
heat treated, the additional expense of buying a quality
barrel from a supplier like K&P or Lilja would make sense.
New surplus M2 barrels sell for about $150 and a top quality
barrel will be under $500. You will still have to
machine the M2 barrel to fit it with a muzzle brake and
you'll probably want to contour it as M2 barrels are ugly.
Consider purchasing a quality receiver too. A failure of the
receiver can be extremely dangerous considering the
10,000+ ft lb energy of the .50 BMG cartridge.
Even if the action will hold the pressure, an accidental
discharge while the bolt is out of battery will ruin your day.

I don't know but I have a question for all you 50 BMG builders. Using
the machinegun barrel why couldn't you use some type of falling block
or removeable block type reciever. Seems like it would be eazier to
machine and would be cheaper and just as strong as a bolt action.

I have a friend in Amon Jordan who is a real gun bug and when he saw the
rifles that I took to Jordan to demo to the Jordanian Military he
decided that he must have one, Since there is no barrels available in
that country he would have to make one . The novel approach startled me
even though I was familiar with the gun makers of Pakistan who could
make a revolver with only a drill press I could not believe it would be
posable to make a 50 cal. Rifle completely by hand. The steel blank was
drilled by hand and reamed the same way. The button was also hand made
and pulled through the barrel using a mechanical lead screw which was
cranked with a wrench that pulled the button threw the barrel using
transmission oil as lubricant, I have seen worst barrels made in this
country by men with a whole shop full of equiptment. The action was a
bolt action made on the shell holder type what again you couldn't tell
that it was hand made.The moral of this story is that it is posable to
do anything you set your mind to if you have the determination to try
and the patience to stick with it.

The aircraft MG was the M3; I dunno if there were also some changes to the
bolt to help increase the rate of fire (around 1100 rpm, compared to the
450-550 rpm of the M2HB).

This could be difficult/impossible with the newer M2HB barrels, they have
a liner (stellite or chrome, not sure which). Easy enough to check for:
the lined barrels will have a visible line or gap in the bore about 2 or 3
inches forward of the chamber. The Army is trying to phase out all of the
unlined barrels, so you might be able to find one of these cheaply.

As one correspondant to this newsgroup discovered to his cost. The
failure of one small component while chambering the cartridge resulted
in an out-of-battery explosion and severe burns and serious other
injuries to the shooter. He's recovering.
