Many here don't like the tactical carry handle from RRA for some reason.
I will say, it seems like extra weight.
Some say the finger holes are too small to use.
There was also a problem with co-witnessing, and the height of the handle. (I'm not real sure what the issue is with, I've never had one)
I would suggest you order in parts. you can save $70-100 by not ordering a complete rifle.
There's a use tax you pay on complete rifles.
Order a complete upper, and a complete lower, then order a 30 roun mag, and you are good to go.
Oh yeah, check out ADCO for you RRA needs. Best price. But sadly, eveyone seems to be out of RRA lowers right now. You can try Stag Arms. They are purported to be manufactured by the people that make RRA's lower.
I'd keep an eye toward the equipment exchange for a lower receiver. I can't find any anywhere right now for some reason.
Here's my recent NOBAN
Seems similar to what you are looking at.
I am going to turn down the barrel, and shorten it to 14.5 soon.
With YHM 2-piece handguard... ~$120 from EE.
