Need advice/opinions from AR guys
Want to build/buy my first AR. I'm pretty sure on how I want it set up, but there's still one thing up for grabs. I'm trying to decide to go with a 7 or 9" rail, the 7 with the standard FSB, the 9 with a LMT fixed front sight that looks like he top profile of the a-frame sight. I don't imagine a perfomance difference, so the issues (I think) are weight (it's going with a magpul UBR stock, very heavy, so longer rail might be better), and aesthetics (can't find a pic of my exact setup).
If it helps, here's how I'm gonna do it:
Anvil Arms upper and lower (might go BCM upper and a lower with good match if you can talk me into it)
Daniel Defense Lite Rail
LMT fixed front and rear sights
BCM bolt carrier
14.5" (pinned w/Vortex) Barrel, Any advice on barrels? I'm thinking LW, Noveske (if I can get a carbine setup??), Sabre Defence....
RRA 2-Stage Trigger
Aimpoint m4 w/Bobro mount, preferably with lower 1/3 riser.
So what's it gonna be?
