"These mag holder are awesome, especially for the price, though they do require minor modification.
If you want a sum up here it is.
Holds mags very snug (even when crawling)
AMAZING price point!
Love the camo options.
Easy to attach to molle (easier then a lot of soft shells)
Comparable to the HSGI taco's in design/hold, but 1/3rd the price
Needs to be beveled (can do with a dremal+sander) for better mag replacements
Solid square design can knock the wind out of you when you dive (see full details below)
Now lets go through the full details.
1st off. They hold the mags very well. So well that I can crawl (with them between my chest and the ground) and they do not slide out. To me I require this because I do a lot of flanking, most of which is crawling. I've occasionally crawled more than two miles in a single game day.
2nd. They are very easy to pull mags from. This particular design if you pull it away from your chest (prying the slot open) it releases even easier.
3rd. They require some brief modification, to bevel the slot's opening. Think of a pistol going into the mag well. Not beveled, the mag has to go in perfectly or not at all, allowing no breathing room. If you buy a mag well bevel, it allows breathing room, easier to reload. IF you bevel the magwell which can easily be done with a dremal and small sanding disc (or even done with a hand file though it'll take longer) putting mags into this is 100x easier. The mags fit so perfectly it has to be beveled, or you will spend a lot of time attempting to get it in.
Now that I beveled the mag holsters, I can removed and replace mags in a matter of 1-3 seconds per switch. This allows me no need for a dump pouch. Personally I can't stand dump pouches. For many reasons. 1st, they look like crap. 2nd, they flap around causing noise. 3rd, when full your mags swing and spank you with every stride. 4th, when you play how I do (constantly jumping, diving, rolling, crawling, etc) you're body weight gets on every side at some point in the game, it's not fun to lay down on 6 mags shoved into your side/back. 5th, one less thing to carry. 6th, when full, dump pouches are known to allow things to come out (out of the guys that most often lose things, almost all use dump pouches, I have never lost anything on field).
I've tried many pouches. Simple velcro pouches (my least fav) HSGI taco pouches (just as good of pouches, though they are 3x as expensive) even these mag pouches that are dual mag but shove the next mag forward when you pull the other mag out. Also an awesome design, but they were about 40$ per dual mag pouch. I still enjoy these pouches the most, and the price point makes me love them that much more. Highly recommend to any M4 users. I hope to see these come out in a few more mag sizes (SMG mags, Sniper mags like SR25, Extended pistol mags, pistol mags, etc) Just hope they learn to bevel them for us.
