Not my first Grendel but it is my first complete build. I would like your opinions.

Hello Everyone, I am 48 years old and live in south Texas. It has been about 5 years since I was on this forum. I have a Sabre Defense 20” Grendel that I use for deer hunting. I reload, and have been using 100 gr NBT & 100 gr Partitions. I really like the cartridge and have taken quite a few hogs and deer with it. I am starting a new build and would like everyone’s opinion on the parts I am planning on using. I wanted this to be lighter than my scoped Sabre with faster target acquisition . I plan on having flip up irons and some type of red dot or eotech. I have a stripped Spartan billet upper & lower, and I just ordered a barrel from Brownell’s. It is an 18” medium contour. The parts I am considering are: MI Gen II SS 15” rail, Ace Stock ARFX, low profile adj. gas block SLR Sentry 7, and RRA lower parts kit w/ NM trigger. I know this is not everything but it is all I have looked at so far. This will be my first complete build. I would like to know if I am on the right track, or if there are better options. I was thinking the long rail would be good because of added distance between front and rear sights. I am really not sure if I need an adjustable gas block. Any opnions on this build would be greatly appreciated. Thanks .
