Though this is a different brand, the idea's the same. Here it is on my lefty AR. Makes weapon clumsy to carry and handle, and HEAVY. Good gear for gun-shop commandos who envision standing off hordes of bad guys from a static position. A pose-tool IMHO.

I am a huge fan of the Magpul magazine pull tabs. There was one in the upper right hand side of the Thor Defense picture. These are worth the cost and are available for both 5.56 AR-15 style magazines and .308 M1A magazines. The .308 size also works well for Saiga 12 gauge shotgun magazines. They do make it easier to grab a magazine and load it.
I am not a fan of the various schemes to tape or mechanically attach two magazines together. These are awkward and do not fit well with most web gear. These will slow you down, particularly when you need to fumble to put the used one back into a magazine pouch. If you really need a larger magazine, get one of the 100 round Beta Mags for AR-15s or M1As -- however these are heavy and really only useful for use in fixed defense positions.
Spend your money on good webgear and then practice, practice, and practice your reload / malfunction / transition to pistol drills. Load a bunch of magazines with 2-3 rounds and use them to practice your reloads. If you have practiced enough such that you have the right muscle memory, you do not need the mechanical attachments. Smooth is fast. Magpul Dynamics has two "Art of the Carbine" DVDs that do a good job demonstrating how to do these transitions and how to run drills that will make this second nature. If you get the opportunity take one of the Magpul Dynamics classes. I also highly recommend taking the two day weekend carbine and high threat contractor classes that Tom Perroni and Joe Trindal teach at Commonwealth Criminal Justice Academy http://commonwealthcriminaljusticeacademy.com/ - they are one of the best bargains for world class training.
I tried a similar brand on my AK, but it seemed to throw the weight off kilter, so I went back to just changing 30 rounders, and it's about as fast if you have your extras on your side/front.

Locking/Taping Mags together: BAD idea! The tried and true method of single magazines for designed loads (20 to 30 rounds per mag) ensures optimum performance in a bad situation. The additional weight of the loaded mag taped or locked onto the inserted mag could, depending on the free play of the magazine locking device, put just enough space between the bolt and top round in the inserted mag to cause a failure to feed, among other things…Believe it or not, you can learn/teach others to count rounds so they are pretty sure of how much remains in the mag. Add in the practice of loading one less round than full capacity to ensure the mag spring is not over-compressed when inserting a full mag into the well of a rifle with the bolt closed. These, coupled with the time-tested practice always replacing a partially loaded mag with a full one during any lull and then topping off the partial mag as circumstances allow is a lot more ‘sure fire’ (pun intended) than the practice of locking/taping mags together for the following reason: Psychologically, the shooter will tend not concern himself with fire discipline because of the false sense of security provided by having so many rounds at his disposal. Additionally, ‘murphy’s law’ will come into play, and that bottom mag’s feed lips will get bent, mud will get caked on top of the rounds, or something else will happen when the shooter least expects it. Sure, you can put a rubber cap on the bottom mag, but that negates the purpose of having two readily available mags in the first place. So why do it?
FWIW, folks who are seriously training need to keep it simple, keep it effective, and not fall into the trap of ‘reinventing the wheel’. Repetitive practice with the chose platform is what makes the shooter accurate, smooth, and fast.
Getting threepers to the necessary level of skill mastery is hard enough without adding 'gucci gear'.
Try herding cats....it's similar!

On mag couplers: These have their use, but I don't belive I'll ever buy one. Guess I'm too small of a niche market, having to account to myself for everything dropped. Your comments on prone use, and about replacability of the gadgeted two mags lost, are in line with my thoughts. My opinion for a person without a logistical tail, is that it is better to train realistically for the fight that you don't want to have, rather than to buy a widget that addresses just a tiny bit of the Big Life without a logistical tail.
On the M1 Carbine mag dust covers: They are not so much of a bad thing to have and use in any circumstances. Especially if you have gone down the road of temptation and have put a stock pouch on the Carbine. That's a bad thing in and of itself, since it takes so much away from the handiness of the gun. But if you have done so, then use those dust covers on the mags in the stock pouch. The Carbine is a niche weapon, it serves best unadorned. Piling weight onto it (even though that was done in WW2) is not a smart idea. Put spare mags somewhere else: Alice M1956 small arms ammunition pouches, Sneaky Bags, pockets in clothing, bandoleers, etc. Any of these ammo carries frees up the gun to serve better in its intended role.
When I was a squad leader in Iraq a lot of the guys were buying these mag
couplers and having issues with them. I actually found a cheaper and superior
way to solve most of their problems. We all sat down, ate the crackers out of
an MRE then folded the wrapper up. Then I had them electrical tape the wrapper
near the middle of the mags then tape the bottom half of the mags together,
keeping them perfectly aligned. When you perform a reload the mags split apart
just enough at the top half to clear the mag well. The best part is how much
space was saved. You didn't have to waste precious seconds to flip the mags
over or do anything funny and they'd fit just fine in a double mag pouch. I've
always said that electical tape is a grunt's best friend and these mags lasted a
whole deployment and worked far better than the guys who had spent money buying
couplers. I hope this explanation made sense. Keep up the good work.
