Looking at putting together my first custom build in 5.56. I have a threaded Aero Precision receiver set, trigger, parts kit, buffer tube, stock and grip so far. I'm planning on getting a standard 16" length barrel with a mid length gas setup. I'm also going to get a standard weight BCG.
With that said, does anyone have advice on gas block and buffer spring? If I have a 16" barrel and a min length gas setup, is it even worth messing with a variable gas block and alternative size spring combination? Excuse my ignorance as I've never fine tuned such a rifle.
Just for simplicity reasons, if the mid length gas setup takes care of any over gas, I would prefer to just do a basic low profile has block. If I went that route, what spring would you go with? Do any of these questions depend on choice of ammo. I was thinking of using fairly standard load 75 grain rounds if it matters.
I was planning on this weapon being for closer quarters out to around 200 yards urban sniping missions. Thanks in advance for any thoughts.
