Here you be. A real deal for you guys who have to keep both Ml and M14 rifles mixed together in an Ml or M3 arms rack. Or keep just the M14 in the racks. Sure ... the racks'll hold either rifle without changing a thing. Trouble is ... a guy with a hankering for his own personal arsenal, plus a little know-how, can make off w ith any M14's that're in the racks. And things get a mite hairy around the company area when a weapon disappears. The deal is to have the racks fixed so's they can hold either the Ml or M14 , or a mixed batch. And it can be done-with the help of your support unit. All you have to do is pass along the scoop that you're going to read next.

Once you're reody to re-do the locking bars, lake them off the orms rock ond then remove the four rivets and leather pad from each bar. That's to stop scorching from torching as you'll see laler on.

Now you toke the four short pieces of bar stock and get ready for some experimenting. While you (on probably get away with having each piece 21/2 inches long, it wouldn't hurt to make 'em 2s/s inches long. The arms rocks don't get made to dose tolerances, so by making the four pieces 2% inches long, you have something to ploy with. You (on always saw off any extra.

Then comes the time to start assemblying the modified locking bar 50'S you can set up things for welding. Get yourself some (-clamps and clomp the short pieces to the locking bar. Here are the approximate dimensions you want before you tighten down the clamps.

Then comes the time to start assemblying the modified locking bar so'S you can sel up things for welding. Get yourself some (-damps and damp the short pieces to the locking bar. Here are the approximate dimensions you want before you tighten down the damps.

Now slip some 1ft_in thick pieces of metal or wood in the bottom of the arms rack-where the rifle butts sit. One day, the M14 is gonna have a hinged butt plate that'll add VB inch to in length. And the shim'lI help take care of the future.

Next ... with a rack of M14's or Mrs mixed, put the locking bar in the rack. Put the bar in the right-hand slot first, then move it over so part of it slips into the left-hand slot. By pUHing the bar in the left-hand slot first, you'll find that one or more of the short pieces-they can be called support brackets-will hit the M14 sight.

OK ... so you stick the bar in the right-hand slot and you find one of the support brackets hits an M14 sight. No sweat. Loosen the damps that hold the brackets and move them a little bit-to the right or lelt-whatever you need. Then put the long piece of bar stock on the top of the support bracken to see how it fin befween

But the brockets ought to come pretty dose to hitting the center of the long piece of bor stock os the sideview shows.
