New to the AR15 platform, I was interested to here what everyone is using for your's. I'm much more familiar with the products I use on my handguns, and though I trust their performance I would like to hear suggestions for the AR specifically. I didn't know if dry lubes worked better in some areas than typical wet lube, things like this? I bought my M&P15 new and I'm getting ready to go over it really good before I take it out for the first time this weekend. On a completely different note, I also purchased a Brownells trigger spring kit (reduction to 3lbs I believe), any opinions on whether or not I should install it before I actually shoot the thing as is from factory? Thanks in advance INGO.
