Whats the word on the straight mags? Will they work in a properly build semi-auto rifle using only FMJ ammo?

Opinions vary. What it boils down to is you've got to try them in the gun and see. They work fine for some, and are slightly problematic for others.

+1 for the dawg. The straight mags can be hit or miss. Typically more hit than miss. This is why H&K aborted them for the more reliable "curved" mags.

I have one and as the two above have said its not completely reliable. But it does have a cool factor in that it has "HK mp5 SD" on it. My other normal non Leo mags only have a date stamp.

Have seen Factory MP5s that dont like straight mags with ball ......

The straight mags were abandoned due to reliabity issues with certain geometry hollow points.
