MP5 Triggers for Dummies

Picked up the AP5-P Grey Team deal last month. Lots of upgrades. As I'm fairly new to MP5s, I did the trigger learning curve thing. Here's the bottom line: just get the Timney trigger. Drop-in for an SEF lower, and it's night-and-day better than stock. I should have gone this route from the beginning, instead of finding upgrade parts for the stock system. Pic in comments.
