Use quality lower parts. I prefer Colt (G&R Tactical, Specialized Armament) but BCM's is quality as well. G&R Tactical has one they make from a couple different quality manufacturers. Those are really the only three I'd use. LWRC is supposed to have a decent one but my experience with them has been less than stellar in the past.
Stay away from DPMS, Rock River (especially their two stage trigger), etc. I wouldn't use the Stag kit either but it's likely better than the DPMS kit.
As far as other components, the only other triggers I'd use would be the Geissele SSA or similar offering from them or their ALG triggers. Wilson's TTU is solid, but I don't have any time with them. I would not use any competition triggers like Timney.
Battle Arms Development offers a great selector. It's an Ambi selector, by I use them because they are so precise and very secure and "snappy" in operation. If you should ever decide to buy one, mention me when ordering and Roger will hook you up. I use their 90 degree CASS-3p selectors with a standard left side lever and thin right side lever.
When installing the bolt catch, watch some videos first. Using the wrong tools will scratch your lower. When installing the trigger guard, support the trigger guard ears of the lower. I can't stress these two things enough, especially the trigger guard. There's enough pics of them broken off to show what can go wrong.
