To Know A Good Magazine Coupler:

  • Material – The material of the magazine coupler is a crucial feature that determines if the magazine coupler is good or bad. What it is made out of will determine how long the magazine coupler can last and whether it can really do its job in holding the spare magazine. High-quality materials like polymers are likely going to last for a long time and can withstand harsh conditions. On the contrary, a bad material magazine coupler is likely to break easily or even damage your magazine.
  • Functionality – A good magazine coupler should be able to allow you to release your magazine as quick and as smoothly as possible, it shouldn’t be an obstruction to your reload. It should also keep your spare magazine secured when firing or when you are moving around. If the magazine coupler is not able to do that, then it wouldn’t really be considered as a good magazine coupler. It would be more of a nuisance.

Definition of good and bad can vary from person to person, the guideline above is just a general way of determining whether a magazine coupler is good or not. At the end of the day, it will still depend on you to decide what you want from a magazine coupler and for you to determine if that is good or bad.

Frequently Asked Questions (FAQ)

Q: How many AR mags is enough?

A: Typically, 30 magazines of 30 rounds each is more than enough for your AR-15. After a while, just about 10 magazines of 30 rounds will do.

Q: How many rounds of ammunition do soldiers carry?

A: An average rifleman carries about 150 to 240 rounds of ammunition. That would be about 5 to 8 magazines. Soldiers would also try to minimize the weight they carry on them so the more magazines they carry the harder it is for them to travel. 

Q: Are AR-15 magazines universal?

A: Yes. AR-15/M-16 magazines are designed according to the NATO standards. This is to make sure that the magazines are able to fit another rifle. 

Q: Can you tape magazines together?

A: Yes you can. But it is not recommended to do so. If you tape your magazines together, one of it will have to face up and the other facing down. This will cause your AR-15 to be taller overall and can be very troublesome when prone.
