Extendind AOL in aics mags

Look at the front of mag, there is umm 2or 4 spot welds (look like little divots) drill them out and the plate should pop out , with maybe a little prying to break the paint
 
I've been planning to do this as well however keep in mind though that in order to actually take advantage of the extra room you have to cut a notch in the bottom of your action otherwise it is a waste of time.

At least in 700SA

I did some measurements and the bottom of the action where the AI mag goes in is flush with the inside measurements of the AI Mag. If I take out the metal piece in the magazine and extend my OAL then the tip of the bullet will hit the bottom edge of my action. You only need to open it up a little however it will void any warranty.

I spoke with the guys a Stiller Precision Firearms in Vegas at SHOT back in January about it. They said it is commonly done and recommend using a round drill bit rather than cutting a Vee shape as it will make feeding better. At the same time he was ok about doing it he also said that it will void the warranty. I am planning to do it with my stiller action, hence my conversation with him, but I'm sure this also applies to any firearm/action maker.
 
yes I saw a few pics on other forum... was just wondering ow to remove the plate

Some ay to weld the ''holes'' to close them?? Wonder if epoxy putty would do ??
 
If you're doing this for a factory 700 rifle, you will need to cut the feed ramp otherwise the tips of the bullets will get hung up underneath it. That is why the plate is there. You need to make the cut wide enough otherwise you'll get hangups. Just making a little notch is a recipe for trouble. It may work if you're only cycling the action slowly, but if you do it quickly you'll still get some jams.
