Have Urgent modification work orders got you and your equipment pinned down these days? You can' t move, shoot or commu~

nicate because some Urgent MWO's are not applied? Then, lend an ear and let's see what you can do about it. You know, of course, that AR 750-5, Change 2, Para 41 says that equipment won't be operated if it needs to have an Urgent MWO applied. OK. Regulations are regula-

Yup, life gets easier all the time ... it says here in ,m,lI ,,'m F'cinstance-in this day and age of weapons with fixed head space-ruptured cartridge cases pop up few and far between. Still, if you run across one in the co-axial M73 7.62-mm machine gun mopnted in your M60 tank, it's sona comforting to know you've gOt a (aupia three ways to get the culprit oue. Right? To begin with, if you're not the guy that all that anti-personnel fire is blasting away at-you could shove the ruptured cartridge case extractor into the breech C!f the gun---climb outside-and use your cleaning rod to ram out the bad cartridge along with the extractor.

F'rinstance-in this day and age of weapons with fixed head space-ruptured cartridge cases pop up few and far between. Still, if you run across one in the co-axial M73 7.62-mm machine gun mO\lnted in your M60 tank, it's sona comforting to know you've got a coupia three ways to get the culprit out. Right? To begin with, if you're not the guy that all that anti.personnel fire is blast· ing away at-you could shove the ruptured cartridge case extractor into the breech of the gun--climb outsidc-and use your cleaning rod to ram out the bad cartridge along with the extractor. How-so-ever, if the climate outside sorta suggests it'd be a pretty good idea to stay buttoned up, then you're down to two pO!;Slo",,!~es.

This gimmick looks like a bent piece 01 cleaning rod and is threaded on one end-so it screws into the base of the ruptured cartridge case extractor, like

Remember one thing. If you get the job done with the handle fix-it means you've gOt both barrels

ready for action. If you go for the barrel-switching routine-you've still gotta get that cartridge Out before using the barrel again. It simmers down to using whatever way suits you best. What counts is that you pick the one that gets the job done the fastest-the bestest ... and the easiest.

Does chamber cleaning time on your rifle mean bleeding knuckles and busted brushes---or have you got it down pat? Word has it that the getting out of the brush-more than the putting in -is causing boo-qoo problems. Like gctting the brush out of the chamber-without cracking the plastic ratchet head, bending the cleaning rod , or swcating blood. And now. more than ever before, under the new system of cleaning your rifle only once after firing-it makes extra good PM sense that the chamber cleaning you do is done right. 50-0-0, to cur down on the wear and tear on men and machines, here's a by-the-numbers picture story of the right way to get the job done. Putting the brush in is the same on both the Ml and the M14 rifles-so, except for the removal of the brush in the M 1, all pictures show the M 14 rifle. The accent in this picture story is on the position of the hands and the cham-

ber cleaning brush ... but when you're working on your rifle, make sure the butt is wedged tight against your body for support. Here's a close-up view of the Ml and M14 cleaning brushes compared to the ammo used in each rifle. You can see that the different size ammo means the brushes are different. Make sure you have the right one for your rifle. MI RIFLE CHAMBER CLEANING BRUS:
