I just picked up my complete lower yesterday, and when I got it home I noticed that the color of the stock is off. It's... dark gray? Alsok where the sling attachment is, it appears to be stained or something, because there is an area around the sling attachment that is definitely black. Is this normal?
(edited to add a question I forgot)
Secondly, when I picked up the lower at the dealer, the hammer was cocked. I won't be getting the upper until after February and won't be shooting it until March. Should I store the lower this way or should I release the tension on the springs? I'm aware that I shouldn't just pull the trigger and let it fly, but what about gently releasing the hammer and putting a cleaning patch or two between the hammer and the bolt release? Which is the best way to store this thing?
