So far for me.
Magpul m3 fine
Larue falls out like every other round
Magpul gen 1 falls out every other round
1 of 2 Kac falls out under recoil but not as bad as larue. Can't see any difference between them.
D&h steel 20rd ok
Brownells aluminum fall out 3-4 times over a full mag
Lancer I have tried but I haven't run through a full mag yet.

All of these mags are new or fairly new with the exception of Kac.

Have you contacted DT about this?

Not as of yet. I've contacted them about the over gassed, rim ripping problem, and a charging handle issue. I'll probably send it back this week. I'm just trying to throw as many different things as possible at it so I have a more complete list of problems.

A ProMag in the hand... is worth two MDRs in the bush.

Is that your nice way of saying they are s***? I've never seen anything about them before, so I asked.

While I agree promag isn't ideal, acting like you're hot s*** and scoffing at the thought of buying cheap magazines when someone is asking about it because they either haven't had any experience with or haven't heard of the promag brand brings to mind images of Victorian age royalty complaining about the peasant class and screaming at their servants to bring the dogs out to chase the folks who use promags.

Btw, I don't believe I have any promag mags, and to my knowledge I only used one several years ago, and it worked fine. They aren't high quality especially compared to Magpul or Lancers, but they are a legitimate option to save money, especially with having spent 2500+ on an unproven firearm with teething pains are starting to show. If someone has a question, maybe don't act like the thought of promags makes you sick and explain why you don't like them.

I heard inserting a pro-mag in any gun is considered gun rape and is known to the state of Kalie to cause cancer.

I have used ProMags with multiple firearms and have had mixed results. The steel mags they make for my Beretta Cougar 8000 9mm have run flawlessly as did the magazines I had for a Hi Point carbine I used to own. I was not impressed with the ones I bought for my Masterpiece Arms 5.7 x 28mm carbine however. I was constantly getting double feeds as the feed lips flexed so much the follower just pushed two at a time every 3 or 4 rounds. Just too flimsy.

Bottom line is that economy equipment can save you money, but you take potluck with quality at times. I would risk buying ProMags for the MDR perhaps for the range only. IMHO

I have not seen anyone else make a 40 round mag for 308 that could fit. Not that i would use one often but the novelty of it sounded like fun.

Literally just did a google search for promag .308 and it came up with a .308 30 rounder for 12.99 on gun mag warehouse. I'll also say that when I was a cashier for 2 separate major retailers (at least here on the west coast) promags were sold for roughly 60-80% what their Magpul counterpart was. And while lots of us are pretending to be operators who need 100% reliability and anything other than the best thing is the worst thing, the reality is a lot of us are probably out of shape dudes who just like touching guns because we like them (and there's nothing wrong with that).

Basically, I find internet elitism annoying as f***.

The only Pro-Mag products that I've found to warrant the knee-jerk skepticism and hate are the old Glock hi-cap mags they made right before the ban in 1994.  They were simple plastic tubes that could hold ammunition and feed it, but the plastic was soft and very flexible, which caused all sorts of issues in a gun not known for issues.  To Pro-Mag's credit, they did offer a "lifetime replacement warranty" (at the time, don't know if they still do) and whenever you had a problem they'd replace it...with another one.  I did hear from a few people that once the AWB expired, they contacted Pro-mag and had them replaced with mags that actually worked.

Regarding the comments about elitism...I agree.  Some people don't have a lot of budget dollars to spend and if the choice is one "cool brand" product that all the cool kids and wannabe operators have to have and something from Pro-mag that will allow them to maybe buy two, it's a hard choice.
