Magpul 40 Round PMag Review

I've been using these mags for a couple weeks now and here's a quick rundown of the new 40 round Gen M3 PMag from Magpul...

Pros:

-100% reliable in all of my riles thus far.

-Compatible with HK 416, SCAR 16, SA80, MK 16, Tavor, ect...

-According to Magpul, more durable than Gen2 MOE PMags

-Same marking system as all Gen M3 PMags

-40 rounds is obviously cooler than 30 rounds

-Compatible with the Maglink

Cons:

-Firing from the prone

-They're tough to find currently

-Currently only out in black

Here's a video review with some shooting, a couple drop tests while loaded, and a discussion/demonstration of the pros and cons:
