    I’ve gotten it into my head that I want an AR and I want to jump in with both feet and build one. I’ve been watching youtube videos and searching here to see what people tend to like and based on that I took a first crack at a [build list]( (still incomplete)

    I’d love to get feedback on whether what I have makes sense, potential alternatives to consider, pitfalls, things I’m missing, and ways to cut down the expense a bit if possible.

    Right now the list is very preliminary and nothing is really set in stone, I mostly just liked the Aero upper and lower in burnt bronze and wanted to make a gun out of those.

    Thanks for reading, all advice is greatly appreciated.

    If it were me I would skip the Fail Zero BCG, I have one and I like it, but I like my much cheaper Toolcraft BCG just as much. I would also skip the SSA and get an LaRue MBT-2S. The SSA is fantastic, but the MBT is just about or equally good for much cheaper. Take the money you saved on the BCG and trigger to get a Criterion Hybrid barrel instead of Aero/Ballistic Advantage.

    Make sure you budget out an optics accessories and tools needed to build.

    You can get Raptors way cheaper than 85. Check /r/gundeals.

    FailZero BCGs have been getting a bad rap here.

    M4E1 lowers are significantly better than Gen2 AR 15.

    I recommend velocity triggers, got a 3.5lb one trigger and it’s been my favorite compared to the POF trigger I have, my buddy’s geissele, and my buddy’s hiperfire (might be spelled wrong). Best of luck!

    1.) Toolcraft Nitride BCG.

    2.) Superlative Arms adjustable gas block.

    3.) Criterion/ADM or Triarc Nitrided barrel. If this is for home defense get an SBA3 brace and a 12.5in mid gas barrel instead of the 16in.

    Get a cheap vise on amazon, Magpul Bev Block, Magpul Armorers Wrench and a punch set with a brass/nylon hammer and you’re set.

    Also a rule of thumb is to invest the most money to make sure you get the best quality barrel, handguard and BCG.

    Spend the upgrade money on 1) barrel 2) bolt.

    Every other “upgrade” from there is mostly a luxury for a combat/plinking gun. Free float is always nice, but if you’re building a short range gun or pistol, don’t sweat the FF. There’s no practical accuracy advantage really inside 200y unless you’re using premium ammo.

    Geissele triggers are of course excellent. I prefer the hard-to-install trigger to a drop-in because of the 99% of the time when you’re not installing it, the Geissele won’t have pin walk or rattle or have weak hammer springs, etc. I think drop-in give up too much for the convenience. Cry once, reap the harvest forever.

    No need for an exotic carrier even if you upgrade the bolt itself. Even a basic nitride Toolcraft is more than enough and the cost if very reasonable. Yes, you can spend $350 for the LMT enhanced, but are you getting real value in return when the cheaper parts function just as well and as durably? I’d rather have three Toolcraft units than a single LMT.

    There are really very, very few truly “bad” options in AR world. Most of it is just which flavor of ice cream you want.

    With respect to your build list, I’d say everything is GTG. I’d personally run a DD barrel just because I’ve had a few thousand rounds on mine and am absolutely impressed with the accuracy and quality and think they are worth the upgrade price. Yes, it’s not cheap going from a $180 barrel to a $280 one, but when you get good-as-it-gets-on-Earth for the price? Might be worth it. It is to me. I’d put Criterion in a similar category even though it’s button instead of CHF.

    For all the Aero Precision parts, consider sourcing them through a dealer instead of direct from them. Often times you can get better prices through a dealer.

    Toolcraft is an excellent BCG for the price, and will save you a good bit of money over the FailZero. Use the saved money to get better quality parts elsewhere or to buy mags and ammo.

    The LaRue MBT-2S or Rock River Arms National Match Varmint triggers are both excellent for the price. Consider these instead of the Geissele to save money.

    Consider Faxon as a competitive barrel option for around the same price, or Criterion for a higher priced, higher quality barrel. Choose a barrel with the features you like at the price you can afford.

    Consider getting a quality generic steel gas block and gas tube. You can again save a bit of money by getting those items from a trusted retailer instead of from a name brand.

    The plastic Magpul and BCM trigger guards work just as well as the aluminum ones, but are much cheaper. Consider going plastic and saving some money.
