Not exactly as advertised - Strike Industries Enhanced Magazine Plate for PMAG Gen 3

Got these for both the added capacity and as a method to quickly identify 300BLK magazines. They are more involved to install than it might appear unless you skip the roll pins. Recommend installing them from the bottom prior to sliding onto PMAG body. I had to slightly ream the holes just to get them started. Really tight fit. However i think the real issue is that I don’t consider these a working +5 extension. The 35th round is VERY tight in the mag and it absolutely will not load on a closed bolt. It also swells the PMAG body to the point that it doesn’t fall free cleanly. I downloaded two rounds to 33 and all is well. Since i went into it looking for a visual cue as well as added capacity - it does work. But there are some limitations.
