Can a AR10 take a unmodifed G3 mag?

[SG1]

What would have to be done to the lower? would you buy one?

[SAnd]

Apex's website show they have used G3 mags for $7 and $9. That may make it worth considering if I was in the market for an .308 AR style rifle.

The G3 mag has an extra layer of metal at the top so it is wider and longer that most .308 mags. The mag well would have to accommodate that. I doubt the mag well wall thickness would allow widening a standard lower. The G3 mag also has insertion stops closer to the top. The well would have to be shortened or groves cut to accommodate them, again I don't think a standard lower would handle that. The latch is different also.

So basically I don't think it would be possible to modify an existing lower.

If you do a 'net search using your post title you will get some hits. One of the hits I got was a 2009 report that CMMG was taking deposits for some lowers. If I was building a .308 rifle back then I would considered it if I could find one.

Hope this helps.

CMMG had lowers that could, I dont think they make them anymore. Some are still bouncing around now. You may get lucky, a lot of people want to switch to the newer pmag compatible ones.

why did they stop making them? what would be the best mag to design a lower to take? in the way of price of the mag? people want to empty their mags, not their wallets....

The G3 mag is a surplus mag. That is why they are inexpensive right now. Sooner or later the source of these mags will dry up and the price will start to climb. At one time you could get FAL mags for $5 or less each. The price had risen to 3 or 4 times that before the current sharp jump. Any lower designed to take a surplus mag from a non-current issue gun will run into that problem. The source of surplus mags will end and prices will rise. One of the things that made M16 mags cheap was that they are producing them in quantity for many current in front line guns. Large production equals less expensive. The current price situation is not normal concerning anything to do with guns. There is no mags available that you can count on being low priced for long in the current market environment.

CMMG has already done the research a development work for a G3 mag .308 lower. A short run of G3 lowers might pay off for them If they weren't already running their machines flat out making regular mag lowers.

I would buy a G3 lower right now if I came across one at a reasonable price. Then I would then immediately buy a lifetime supply of G3 mags or at least as many as I could afford.

This is total speculation on my part.

The three rule of predictions-
1. As soon as you make a prediction you know you are going to be wrong. You just don't know by how much and in what direction.
2. He who lives by the crystal ball soon learns to eat ground glass.
3. And most importantly, if you are ever right, don't ever let them forget it!

A question- Is it 'gouging' if the price of a mag goes from $5 to $9 in less than a year?

Have A Good Day.

To answer why they stopped. The article I read said you had to do a small clearence cut on the upper. That combined with the increasing availablity of other reasonably price mags made the G3 lowers not as marketable I'm guessing.

Well if it is a election year, or after some nuts snapped and the supply is drained in less then a day then, maybe maybe not if you are charge 2 bucks more then no it is not, 60-100 per P-pmag, need I say more?


So the issues is with both the upper and lower? Could it made me to take both AR10 and G3 mags?

Do you think this product would sale? I can find a reason why people would not want a cheaper(for the time being) mag supply for thier rifle...

Anything can be made with enough time and money.

On the practical side a dual G3 / AR10 mag lower wouldn't be practical. There are too many differences between them.

I'm not really into having a lot of mags for my guns. Because of that I don't put a lot of consideration on the price of mags when deciding to buy a particular gun. Everyone has to make their own decision on what their priorities are when buying something.

The MGI guns seem to be popular except they have a reputation of being hard to get. So maybe there is a market for that type of gun.
