i tried looking but my question specifically is this.. i notice there are 20rnd straight bodies and 20rnd curved bodies.. is there an advantage to one or the other and why have they started to do this..? thanks in advance for any help..

This has been discussed elsewhere...to boil it down 1) there is NO advantage to curving a 20 and 2) the general concensus seems to be that curved 20s are easier to produce because the same tooling that can make a 30 can make an "abbreviated" magazine (20 rounder). Me personally I do not like curved 20s...just look wierd. 20s as they were meant to be appeal to me...FWIW

I like straight. the straights are aesthetically nicer looking and I buy into the straight mags feed more reliably (if capacity isn't overdone) than curved.I also prefer the aluminum follower, which is the most durable and probably the most reliable of all designs. As for "Why" they were made, I'm sure someone had the equipment to turn out 30s, and cutting a fabricated 30 down to a 20 from pre-existing equipment is cheaper than seperately buying the necessary equipment to produce straight 20s.

My position is that straight 20s were the INTENDED mag for the M-16 and 30s were the INTENDED improvement. No such luck on the curved 20s.

thanks for the replies, just seems a little weird that they would make the curved 20's.

The curved 20's can actually fit 20 rounds, I think the straights can only fit 18.

Brownell's say theirs are curved so the green followers work correctly, I don't know if it makes a difference. I have 2 of their curved 20's and they work great.

+1

18 rounds as a max capacity or a max "suggested" capacity is UTTER BULLSHIT.


If you want to download your mags by a round or two for tactical reloads, then by all means, do so. Regardless, any quality mag (which includes 98.7% of USGI mags) will have ZERO problem loading to its full INTENDED capacity.

They are to be congratulated...since they came up with a solution to a problem that doesn't exist. Straight 20s do not have green followers! The black or alloy followers in the straight-body USGI 20s work as advertised, at least that's been my experience...

I have 10 D&H curved 20's and never had a problem. The curve matches the natural curve of 20 rnds. stacked on top of each other due to the taper of the cases. The straight 20's wewere issued in the service were always double feeding. Use what works over what looks good or some sentimental horse shit about what they originaly came out with.

So what? Oh yeah...40 years later some genius picks up something Eugene Stoner missed...

Cite credible sources or keep the regurgitated heresay to yourself.

Again, brownells and everyone else who thinks curved 20s are "en vogue" are fixing things that ain't broke. Sentimental? now THAT'S a load of horse-shit. All my straight 20s WORK. Thanks - more for me.

Hey HP40, I HIGHLY doubt that D&H went with the curved 20's because the straight's weren't reliable.

USGI 20's (or NHMTG 20's with aluminum followers) are known to be some of the most reliable 20's out there.

Here'sa pic of a Bushy (D&H) 30 and 20rder that will pretty much point out WHY the curved 20's exist at all.

EASE OF MANUFACTURE!!!


That's all I have to say on the subject.

Really? They were always double feeding? That is quite interesting..

The D&H mags are curved because 1) you can use superior green followers over black and 2) existing 30rd tooling can be used. Its followers and money, SIMPLE. Curved and straight are just as reliable

If you like Magpul Ranger plates they work well on the curved 20s. And if you really want to play you can cut about 1/8 of an inch off of the legs of a Magpull follower (plenty of room for the spring as it fits a 30 rnd spring), and you can get 21 roungs in it (foolish) or easily insert the mag with a closed bolt and 20 roinds in it.
