Just ordered a couple of these to try out, but given Okay’s reputation I’m sure they’ll be fine. Anyone used these yet?
I was going to order some also. $10 apiece at Botach. I know, Botach, but I’ve never had a problem with them. Not the fastest shipping, but free.
I use a lot of Okay’s standard 20s and 30s, they are currently the only GI aluminum style mags I use. Intellectually I know I should probably transition completely to Pmags, but I just kind of like the GIs as well. Consequently I still use both somewhat interchangeably.
On the E2, I find the huge “Surefeed” logo tacky, I am ambivalent about the texturing, but I am legitimately interested in the claims of reliabilty-enhancing improvements to the feed lips, because there’s no such thing as being too reliable.
When I see the blue follower I want to think “Training Use Only” 
As long as the low friction feed feature doesn’t cause issues if you slam the mag in too hard, I’m on board. I’m sure Surefeed has tested them thoroughly, though. Surefeed/NHMTG mags are my current go-tos since M3 PMags don’t drop free from my Colt/BCM/KAC lowers.
You must have won the lottery on lowers. I’ve never had a lower that a Gen M3 wouldn’t drop free from. Including Colt, BCM, Armalite, LMT, RRA, and Noveske.
These mags are basically g.i. EPM mags with tacky embossing on 'em. I was in line to test some pre-production ones but I declined because I didn’t think there was anything to discover. Magpul did the R&D on the feed geometry, the government plagiarized it and didn’t come up with as good of a mag. Okay tooled up for production, Center got a sole-source contract, we have ugly commercial mags to show for it.
Mags may not drop free on HK MR556 w/o filing/grinding off a couple dimples.
I have plenty of OKAY magazines but none of the new ones. One their trademarks is coming out of the packaging looking like they were drug behind a truck. It’s the result of being pushed through a die during final inspection. Probably required by the mil. Looks like the dimples would prevent that step from getting done. The blue follower looks like the older green one to me.
Botach (among others, presumably) still sells new Okay mags with the old-school green follower. Can’t imagine that would be a big seller nowadays with all the improved followers out there.
Hopefully someone will dump them for under $9 before the next election panic cycle. I was getting them for around $8 not that long ago.
I have more Okay/NHMTG mags with Magpul enhanced followers than anything, still got packs of Magpul enhanced followers I picked up on sale boxed up waiting for a home.
I can’t realistically see me ever buying an AR mag again. I’m just not wearing any out, and have them tucked in every corner of the house as it is.
Can’t say that I’ve had much experience with them, but were the old green followers really that bad?
I never had any problems with the old, old black followers.
So what is the significance or advantage of the blue follower? New 21st century space age material or construction? They look rather interesting, but I’m mag’d out. Too many of 'em. I was a guy taking surplus GI mags during the 1994-2004 ban and refurbishing them with new springs, followers and a new coat of Permaslik G. Still have a pile of the Vietnam era 20’s as well.
Same thing as the tan follower but blue.
The black and green followers really do fairly well with the 20" rifle, but when you speed things up, they have a hard time keeping up.
I think I remember reading about the change to blue followers had something to do with M855A1 EPR round the Army adopted. Apparently without it, the bullet tips were causing damage to barrel extensions .
That was for the Army’s new tan EPM, which has a different shade follower. I don’t think it applies to these. Also, that was found out to be false info.

My bad I thought these were the new EPM’S.
Looks like in the picture the top round is on the right, like a green follower.
You aren’t alone. Same experience for me; although, I only use them for things i don’t need right away, and only if they are the lowest price.
