Just a notation on MP5A4s and A5s

[MT2008]

This is a mistake that's mostly made due to airsoft. The Japanese airsoft gun manufacturer Tokyo Marui makes an MP5A2 and an MP5A3 with a Navy trigger group, but calls them the "MP5A4" and "MP5A5" respectively. Somehow, their mistake seems to have spread across the net, and now, everyone seems to think any MP5 with a Navy trigger group gets the "A4/A5/SD5/SD6" designation. When I used to post on airsoft message boards (years ago, now), I used to correct people on that nomenclature all the time.

Thanks.

I always thought it's four positions only? The way I understand it, only MP5s with safe-semi-burst-auto lowers get the A4/A5/SD5/SD6 designation, while anything less than 4 positions is an A2/A3/SD2/SD3 (depending on stock or presence of integral suppressor).
