Can anyone attest to how durable the Magpul Ranger plates are?
Wanted to know if they would hold up to being dropped on concrete

I don't use the Magpul Ranger floorplates, BUT I do use the Magpul Ranger L floor plates and they are MUCH better than the factory stamped aluminum units.

Arent those ones made of some rubber to absorb the shock of being dropped?

Yes, they are a dense rubber.  I would think they would be the best, but I think they are insanely priced.

Ridge line is correct on all of his comments (including PRICE )

But they have a stainless steel plate manufactured into the rubber to function as the floorplate, it's NOT going to fail like the factory plate can!

Plus they make the removal of the Floorplate easier.

This. Good product, good concept, but goofy price. I see them as basically an insurance policy to reduce the likelihood of damage to the magazine. Thing is, they cost nearly as much as a new magazine. I just don't see paying $9 for an insurance policy on a $10 item, anymore than I'm going to pay $9,000 for an insurance policy on a $10,000 vehicle.

Brownells has them at $18.95 for a pack of three, that's $6.31 each.

They can be found if you look hard enough for just over $5.00 each in three packs, yes they are pricey, thats why only thirty of my "go to" mags have them.

I always thought these were used mainly to aid in resting the mag in the "Prone Position" being the bottom is rounded (where you wouldn't ONLY have the rear edge of the mag a flat bottom) to tilt the rifle higher and lower while Prone.

Figured they were "Prone Cushions" (in a sense) (and finger loops for quicker reloads also)

Or are these strictly a "Drop cushion" to prevent the rounds from launching out of the feedlips if you drop one? I thought the "L Plates" were for that!?!?

They help with drops but they're also useful for getting your mags out of a plate carrier or chest rig.

L plates are more of a drop cushion (and, as others mentioned, probably a bit overpriced, especially in the current magazine pricing market).

I've got 28 USGI 30rd mags with half black, half flat dark earth Ranger plates since around 2008 and they're still currently going great.

I use the different colors plates because I load 55 grains bullets on one color and 62 grains and heavier on another color.

The Ranger plates do absorb shock when dropped on concrete or hard surfaces, the material is called Santoprene (*r) synthetic rubbery type material.

I only broken one Ranger plate when it was stuck on one of my mag when I was removing it, the bottom of the mag is out of spec and I forced the Ranger plate with too much force and broke the loop, it was my own fault.

Mostly I look around for a good sale price to avoid paying full retail for them, I mostly use them on my mag chest rig (6 to 12 mags), they're very durable and would highly recommend them.

I've dropped my Ranger plates on concrete and gravel with no issues.
