Inevitably, at least one or two of those small springs will go flying off and can be a bitch to find.
When it gets time to install those small springs and detents, do it in a small, well lit, enclosed area. The bathroom is ideal (cover the drains).
Honey, what are you doing in there? You've been in there an awful long time.
Just installing the front pivot pin detent and spring on my AR.
Well, you don't have to lie. Come to bed and we'll talk about it. [:)]
