Just some clarification on some of the points made here.
The benefits of using Magpuls over paracord loops is directly related to the pouch or vest used. As FREEFALLE6 said some mollie pouches have issues but the SPEAR system works very well with them. They were originally designed for use with the standard GI 30 round pouch.
If the pouch or vest functions well with them then Magpuls offer a number of advantages over paracord (which I used for many years).
Some of these advantages are-
* Consistent loop placement from mag to mag,
* Loop always upright and scooped -aiding in reloads without looking down.
* Loop can be notched for tactical id of mags loaded with different types of ammo (tracer light vs tracer heavy)
* Neon colors aid in Live fire range work (like id of frangable ammo)
* Sides of Magpul silences magazines stored next to each other in pouch.
* Sides also have recessed rough texturing aiding in handling under adverse conditions (duct tape is slippery when wet)
* Notches inside loop will release finger easily even if wearing NBC gloves.
* Magpuls can be NBC decontaminated.
* They can be installed or removed from magazines in under 1 minute each.
* Loop acts as shock absorber when magazine is dropped.
* Loop changes the mags center of gravity to a floor heavy bias resulting in fewer "feed lips hit the ground first" damage to magazines.
As for the "Allot cheaper and allot lighter than magpuls" comment, each 5.56 Magpul weighs just under half an ounce and they cost a whopping $2.50 each if bought in a twelve pack.
Another thing to remember is that time is money. A user can install Magpuls on a combat load of 12 Magazines in about 10 minutes. To build quality 550 cord puls, gutted with zip tie inserts so all the loops are the same length would take about an hour for the same twelve mags. This is time that you could be using for training, other prep etc.
In closing, use what you are comfortable with be it Magpuls, parcord, duct tape or nothing at all. If anyone wants to see if the Magpul has any benefit to them, we offer a 60 day unconditional return guarantee so anyone can check compatibility with their gear. They can also see though training if the Magpuls benefit is worth its cost.
