I think oly did a mag inside of a mag type of thing for there 9mm ars so if your talented enough im sure it could be done. Maybe you could use his design put inside a regular ar mag to lock it in place.

Default Both these are 22 LR, not centerfire.

Both are 22 LR, so their magazines are not suited to 223 Rem case diameter.

I looked at all the AR pistol calibers and the mags aren't long enough to accommodate a 1.700" round.

Didn't say use the mag, look to see how the mags were modified so a shorter cartridge could feed properly.

They were designed for the 22LR the ones I saw online, unless you are referring to the very first training rifles which were like M1 Garand's and modified to shoot 22 LR?

Default Magazine solution found and will test it...

Looks like we have a reengineered PMag that will do full duty for the 22 Mamba AR and the designer used it for many other short cartridges. Maybe might work for the 223 Short.

From George based on discussion with designer. "The P-mag's have a cool feature called anti tilt followers, there are 2 ribs in the mag which the .223 shoulder rides near that they also use for the anti tilt feature. You chop the follower just past this point. The spring all resides behind that rib so no cutting necessary.

The metal strip made for the ramp will go the entire length of the mag (top to bottom) and will serve as the new front wall of the magazine. As for the ramp I would think the bottom of the ramp should be just below the centerline of the bullet of a loaded round at an angle to be flush with the top of the magazine.

He said he just used a 2 part epoxy to set the follower in place. Didn't give specific type, but in my experience I would get at least a 3-5min epoxy as the faster ones are stupid fast and near impossible to work with. JB weld would also likely work, and would afford you more time to "set" things before it cures."

Thanks again one and all for playing - got the creative juices going, produced ideas, reminded people of who they know and what they have seen, and helped us find a practical solution. The GBO community does it again.

Couldn't post pics last week as I was out of the country, but that's very similar to what I did with LR308 mags.
