Ultralight Ultralight Rifles

In other ULUL news. I’ve been messing with some Frankenstein magazines to see about single stack possibilities. This iteration is pretty successful so far with the 223 wyld. Hasn’t worked on the 6x45 because the necks are too wide and drag in the 223 cz 527 magazine I used for the internal single stack. It fits 2.40 COAL. Didn’t feed the 2.40s great for angle, but the 2.36s fed fine. Could probably manipulate the feed lips to change that. With my chamber I can’t go much over 2.31 anyways so not currently an issue. Might get a little more serious when I get a barrel chambered for longer seating. About a half oz heavier than a duramag.

That's got potential! Nice work!

They used to make a single stack AR mag for, I think,, NRA Hi-Power competition and shooting heavy bullets, but I couldn't find much info on them. Apparently they went out of use when the 77s designed for AR mag lengths came out.

They must have used the space in the rib at the back of the magazine.

Not sure how well they worked with the AR dual feed ramps, but if they feed well and someone started making something like that again, it would open up a lot of new ground for these rifles.

It can be pretty finicky from lower to lower. Not just the dual feed ramps, but the AR bolt is made to push staggered rounds so there’s a balance making sure it catches the round to feed but also doesn’t catch or drag on the feed lips. These are feeding up the rib in the back of the mag. Which also doesn’t work with a bolt catch (not an issue on my ululs. If we get something that functions universally maybe we’ll have to get something made that @hereinaz or someone else can sell.
