We all get a constant barrage of recommendation requests on this board and probably elsewhere as well. What company should I turn to for this or that? It really all boils down to budget, personal preference, and specific use. Here's what I'm lovin at this moment (no, I don't have it all figured out): Daniel Defense- Best bet for a complete $1500-ish rifle. Great specs/rep, plus a $300 Hguard. BCM/PSA- This is where I turn for builds, time and again. Excellent quality and pricing. Magpul- Great mags, stocks, and furniture. Light, tough, ergonomic, zero rattle, very fair prices. Vortex optics- Excellent quality at a great price. High-end lowers- Build a good gun on a good lower. No, it doesn't necessarily make your gun functionally better. But it makes it more marketable if you ever choose to sell. This is essentially your gun's 'hood ornament'. I'm also a fan of S&W rifles for under $900, Noveske if you want to spend $1800+, most Spike's and LMT uppers, lowers, and parts on the rare occasion you can find them, and Troy/Lancer/TangoDown mags & furniture. I also really like Prvi Partizan's match grade 69-75gr ammo, when available at a fair price. I value high grade equipment at a medium price. I'll pay for quality, but my budget is that of a mere mortal.
