Yeah I'll do that, I was thinking about making a post about it because there are so many considerations you would take into account in making your own perfect rifle. Theres a lot I don't fully understand, like why it seems to be a big deal about the gas block / gas key, and how it is sealed etc. I'm not sure why but a lot of people are concerned about that on quality ARs.
I like that you went flat top all the way along the handguards / floating rail. Some people say that all that rail can add a lot of weight which they care about (if you were packing it around all over maybe it would make a big difference). I don' t think I would use all that much rail, but I like the configurability. Some additions are nice as long as it doesn't get too excessive IMO.
I don't know what you are using for an optic there, Burris something. Are you thinking about a red dot sight or BUIS? IMO from seeing what I have see that is available for BUIS its Troy Industries all the way, the flip up version with the curved guards at the front are what I like best.
I think it would probably be easier to choose a good upper than it is to choose a good lower. Whats in a lower? Well... the serial for one right, and the trigger assembly, but how much goes into choosing a quality lower?
So many questions, sigh. Congrats on getting this project going, i'm envious!
