Saw a story on Drudge about this today but couldn't link it. Basically some tech heads in China figured out how to make pigs glow in the dark by feeding them some sort of algae. Hey, would make night hunting with NV gear obsolete!
Mmmmm... how long before the drug cartels pick up on this? I can imagine waves of cocaine laden drones flooding across the border to Juan and Pepe's rooftop. After all, South America is home to the real Amazon! And not to mention that Brazil has a very sophisticated aerospace manufacturing sector.
If you want a good single stage, check out the ALG Combat trigger. It is named after Geiselle's wife Amy, I believe. I put one in my S&W AR and it works great. About $65 from Rainier Arms.
I will never spend another dime at Dick heads after what they did after the Sandy Hook incident by pulling all their "evil assault rifles" from the shelves.
