The Pics of the 25 round "Straight Body" USGI type mag at retro black rifle have given me an alternative to the waffle mag to search for (I'm sooo thrilled)

What are everyones chances of finding one ? How many were produced ??? Man they sure look different from the twenties ... I couldn't find any... 
...but there's an old phrase we use in the military..."Field Expedient Solution"... 
(P.S. - It requires machine tools + high school metal shop at least)

Wow Postino, that does look nice.
How much time was involved in making it? |

Well I know from past posts and before NDS decided to make the waffles,there were discussions saying that it would cost way too much to make mags,,yea I understand this is probably a 1 off he made,just wanted to know if it's show or show-n-go
ETA either way it really looks fantastic!! |

You are looking at a *lot* of work there, my man...It might as well be made of unobtainium... 
Mike could probably make them at a reasonable price...I sure can't...

Let's get Mike @ NDS interested in 25 rd straight mags...Shouldn't be any more difficult than 20 rd waffle mags...

BTW: There's a reason why Colt/ArmaLite never made 25 rd straight mags in any quantity...It's the same reason that they went to a curved mag...(and why M14's never used 25 or 30 rd straight mags)...
You only have to look at a M16 cartridge and mag...and an AK cartridge and mag... If you put a tapered round in a straight mag, after a certain number are stacked, there is different spring pressures on the front & rear of the top round...and it won't always feed properly...the rear will try to stick up more than the front... By curving the mag, you put uniform pressure on both ends of all the cartridges... I'm still experimenting with feed lip angles on my mags as well...There used to be a company selling a mandrel that you stuck in a 20 rd mag body and lightly hammered the lips to take out dents and realign the lips...Anyone know who it was??? I haven't seen them advertised in years...

I thought I had found a 25 round mag on the back cover of shotgun news in a pof-usa advertisement. I got all excited and went to the website as fast as I could, only to find out it is a 25 round .308 mag. Then went back to the ad and looked again, duh you big dummy, that's not an ar15. Oh well, 5.56 stripper clips only hold ten rounds anyway, makes loading 20s and30s easier.
Looked at Mr. Squirrel's link, looks like the slot to lock in the mag catch is in a different location on these prototype mags. These mags hold major cool factor though. |

With the talk of 25 round magazines, from my understanding, the original FAMAS F1 and G1 used a straight-bodied 25 round magazine that was not compatible with NATO weapons, the later FAMAS G2 used the STANAG magazine. Does anyone know why the French went with a straight-bodied 25 round magazine, and why did it work for them?

But setting the baseplate at an angle (like all 20 rd AR mags) helps; also making the spring curved spreads the pressure if it's curved correctly. I'm curious as to why the 9mm Parabellum round functions in MP-40, Uzi, and Mac magazines of 20, 25, and even 32 round capacities...the 9mm is severely tapered...but it's a lot shorter, so I suppose that helps...
TexSquirrel (and anybody owning an original 25 rd mag) - Is the base angle of the 25 rd mag on your RBR site more acute than the 20 rd mag next to it??? That may have been one attempt to get it to feed reliably... |

I don't know.
I don't think they're laying at identical angles. Anyone got a protractor they can use? I have one around here somewhere... |

http://www.wzrd.com/~rbrennan/misc/25rdtest.jpg I don't have (or understand) photoshop, but if you overlay the 20 on the 25 rounder, I'll bet the angle is a bit more on the 25. Looks that way to me anyway |

BTW: Do we know which came first??? 20 or 25 rd???

Perhaps Mike at NDS was too quick to pull trigger on Waffle mags and shoulda taken a look at these as a project
(JK) HE does not do aluminium mags , but hey NHMTG has been know to do a side project or two (Like the Aluminium 10/20 "straight body" mags they made for Stag a while back) ...

Personally I'd like to see some new 'fully curved' 30 rounders made. The tooling has to be out there, since they were produced by commercial entities. I meant to run a few rounds through the one I have, but ended up just using 20 rounders since I was shooting off the bench. I saw one of these at a gun show several years ago and didn't buy it despite the Colt baseplate. At the time I thought it was some off-brand mag that someone had put a Colt baseplate on.
Same show was where I had a chance at BOTH a 601 and 602 stripped upper - guy had 5 stripped uppers and gave me my choice for $40 or all 5 for $100!  Wish I had a time machine and knew what I knew now.

I bought 2 steel waffle mags, $5 each, from a huge table of various 20 rounders. I just bought them because they were different. This was in 1981. They were traded off long ago. I'm grateful NDS did the waffles. |
