I'm starting my SBR build and I need recommendations. Was thinking about the 10.5" upper from PSA. Anyone have any other recommendations? I already got my lower and lpk so I just need the upper and a stock. Also, what optics work best for sbr's? I obviously dont plan on shooting great distances with it. It's more for home/yard defense. Was thinking a micro eotech would do the job. I have a 552 eotech on my 16" and I wouldn't trade it for anything. Well maybe an acog lol. I need input! I'm excited to be doing another build. Did my first build a year ago and had a blast.
