@SubGrub allow me to make an attempt to help you out here a little bit;
This forum has been around for a little while now, and in that time we've all seen our fair share of newcomers to the platform who show up wanting to build a large-frame AR platform that's perfect for everything from room clearing, to 3-gun, to precision long-range shooting, and they want all of that to come in under 6 lbs as well. Well, it's never happened yet. That's because these platforms will excel at a specific purpose if you build it for a specific purpose, but you need to figure out what your biggest priority is for this build. When you state that precision shooting will be an expected function of this build, your binary trigger becomes an immediate reject, here's why: A binary trigger is most useful for a high rate of fire, everything that will suffer due to a high rate of fire (namely accuracy and therefore effectiveness) goes right out the window with all the dynamics of a high firing rate. Will it dump out expensive ammo really quickly? Yes, but otherwise it will be very unimpressive. Will it dump out cheap ammo really quickly? Yes, but it will be otherwise unimpressive, unless you're interested in communicating how much more money you have than sense to onlookers.
You haven't clearly communicated any real priorities for what this build needs to accomplish, usually folks can at least articulate that they're looking to do one of the following as their goal: minimize weight (it's a large-frame AR,duh), maximize speed (it's a large AR, everything is bigger, heavier, slower), maximize accuracy, maximize effectiveness in terms of terminal ballistics, mock up smaller AR roles and platforms in the larger AR (DMR), hunting, plinking, wasting ammo as fast as possible, etc etc.
Right now the only thing we know with any certainty is which trigger you want, but that tells us nothing definitive about what you want the rifle to do effectively.
