I've seen hiccups with MP 20 mags. I believe it is because the rear leg is short - giving a 'nose up'. (Same ammo - two different weapons). Do the MP followers in the 20 round GI mags have 2 long legs - unlike the MP followers in the MP mags?

There are no MP followers made for 20 round USGI mags. The followers need to tilt just a bit to accommodate the slight taper of the cartridge, when used in the straight body mag.
I be never had any problems with the standard followers in my usgi 20 rnd mags or the magpul follower in my 20 rnd pmags.
The PMAG20 is a pretty well known "risk factor" for reliability. Lots of instances of malfunctions, particularly with failures to lock back on an empty.
The USGI20 is, in my opinion, the most reliable magazine you can buy when outfitted with a standard black or aluminum follower. Edit to add: A Magpul follower will not fit a USGI20 properly.
What about these?

Those are curved and fall into the realm of "What's the point?"Quote:

Lancer L5 Advanced Warfighter Magazines, I love mine. The way to go for 20 round magazines.
Colt made GI 20 rounders were alays 100% for me. Now for 30's I like PMAGs, but in a 20? the GI is the way to go. ther have been some slight sissues with 20 round PMAGS - not sur eabout just followers though.
No doubt. I don't have any problems with the Pmag 20 I own.. but it's strickly a prone/bench shooting accessory.Quote:

Exactly. It's common sense that the USGI20 would be most reliable. The platform is designed to use that magazine. All 30 round magazines are an after-thought, and are flawed in one way or another due to the incompatibility of a curved magazine and a straight magazine well.Quote:

And the Pmag20 has not had a reliable track record.
It always amuses me when people try to apply fixes for later flawed designs to the original, perfected design.
I don't know where all the GI 20 "perfection" is coming from, but I have seen pretty much the same amount of magazine related issues with the 20s as with good 30s, given a working base weapon.
They're ok, but "perfect"?
Come on.
As close to perfect as you're going to get for the AR platform... the magazine is designed for the .223Rem cartridge, and the magazine well.Quote:

The follower legs on a GI 20 are practically non-existent. There's a little foot on the aft of the follower, and nothing up front.Quote:

Left: CMMG SSAT follower, comparable to a MagPul follower.
Right: USGI aluminum follower from 1960s era Colt AR-15 magazine.

Why you aren't going to fit a MagPul or other no-tilt follower into a USGI20. The spring steel tab that retains the floor plate gets in the way.
